Growing regions

The subtropical province wedged between Brazil and Paraguay that grows almost all Argentine tea, on deep red lateritic soils shared with the region’s yerba mate. The defining fact is mechanisation: the crop is cut by modified tractors straddling the rows, taking stem and mature leaf with the shoot, which sets the ceiling on quality and the floor on price. Frost in the southern winter halts growth and concentrates the harvest into the warm months.

A basalt plateau behind Cairns in far north Queensland, cleared from rainforest and planted with tea from the mid-twentieth century after earlier coastal attempts. Rainfall is high and reliable and the plateau is frost-free, but Australian wages rule out hand-plucking entirely, so the whole operation is built around machine harvesting on level ground. The tea is a clean, brisk black leaf sold largely into the domestic market.

The humid subtropical lowland in Azerbaijan’s far south-east, between the Talysh mountains and the Caspian, continuous with the Iranian growing strip across the border. Tea was planted here from the 1930s under Soviet agricultural policy, largely collapsed after independence, and has been partly replanted since. It is the only part of the country where the climate supports the crop.

Bangladesh’s northernmost district, where tea was introduced only from the turn of the twenty-first century on flat farmland close to the Indian Terai. The sector is smallholder rather than estate: growers hold small plots and sell green leaf to independent factories, which is a structurally different industry from Sylhet’s plantation model and now accounts for a growing share of the national crop.

The north-eastern division containing almost all of Bangladesh’s old tea estates, laid out from the 1850s on the low undulating hillocks — locally tila — that rise out of the Surma floodplain. The gardens sit only tens of metres above sea level in a monsoon climate, which gives a strong, dark, quick-brewing CTC tea rather than an aromatic one. Srimangal is the working centre of the industry and holds the national research station.

The river valley south of São Paulo around Registro, settled by Japanese immigrants in the early twentieth century who planted tea alongside rice and bananas. Production grew into a real export industry by mid-century and then contracted sharply as costs rose and growers switched crops. What remains is small, and its Japanese lineage — in cultivar choice and in processing knowledge — is the most distinctive thing about it.

One of Burundi’s principal tea areas, high on the Congo–Nile divide in Muramvya, where smallholder plots sit around a central factory at close to 2,000 metres. The altitude is extreme for tea and growth is correspondingly slow; the district’s output is the material that has given Burundi a quiet reputation among blenders for brightness. Almost none of it reaches drinkers under the country’s name.

The high-altitude half of Cameroonian tea, several hundred kilometres inland from Tole on the Bamenda grassfields — open, cool, rolling upland on the ridge that continues north-east into Nigeria's Mambilla Plateau. The two districts belong to the same continuous highland system and to the same country, which makes the pair a rare natural experiment: the same corporate operator, growing the same crop for the same market, at sea-level warmth in one place and at genuine altitude in the other.

The tea estate on the south-eastern flank of Mount Cameroon, below Buea, and the low-altitude half of the country's industry. It sits in the old coastal plantation belt among oil palm and rubber, on young volcanic soil at the foot of an active volcano, in one of the wettest places in Africa. The agronomic argument for the site is rainfall and soil rather than altitude — this is not a highland tea district and the leaf reflects that, growing fast and heavy in permanent warmth.

A long range running through Zhenyuan and Jingdong in Pu’er prefecture, holding the Qianjiazhai forest and the wild tea trees Yunnan points to when it argues that the plant is native here. The material is genuinely different from the cultivated stock lower down: these are wild-type camellias rather than domesticated assamica, thicker-leaved and often more bitter, and they are picked and processed separately as ye sheng. Ages given for the largest trees run into thousands of years and rest on ring-count estimates and local tradition rather than settled dating.

The Hunan county that is the historic centre of hei cha, producing Fu Zhuan with its cultivated Eurotium cristatum bloom, Qian Liang logs and a range of other compressed dark teas.

A bamboo-forested county in northern Zhejiang whose tea industry was built on a single plant. A pale-leaved mutant bush found on Tianhuangping in the 1980s was propagated as Bai Ye Yi Hao, and its shoots emerge nearly white in cool spring weather before greening as temperatures rise. The resulting tea is a green tea despite the name Anji Bai Cha, and its unusually sweet, low-astringency character is a cultivar effect, not a processing one.

The Fujian county that gave rise to Tie Guan Yin and to the tightly ball-rolled, lightly oxidised style of oolong that now dominates the category commercially.

A mountain in western Menghai on the Myanmar side of the county, with Hani and Bulang villages working old gardens on its slopes. It carried the best-known of Yunnan’s ‘tea king’ trees, a wild specimen in the forest above Hesong whose great age was widely publicised and which fell in 2012 — a reminder that these trees are individual organisms and that the ages attached to them are estimates rather than records. Bada’s own material is generally read as lighter-bodied and more sharply bitter than the Bulang mountains to the east, without their heft.

A town in the north of Fuding county and the third of northern Fujian’s historic gongfu black teas alongside Tanyang and Zhenghe. What separates Bailin Gongfu from the other two is the plant: it is made from the heavily downed Fuding Da Hao, the same white-tea cultivar that gives Silver Needle its coat, so the finished black tea is thick with golden tip. The ‘Jin Hao’ style pushes that further by selecting almost nothing but downy bud. Bailin was a collection and refining point for the export trade, which is why the name travels attached to a manufacturing style rather than to a hillside.

The imperial tribute tea gardens at Jian’an, in what is now Jian’ou in northern Fujian, and the single most consequential tea district in Chinese history that no longer produces anything famous. Beiyuan is where the Song court’s tea was made: leaf steamed, pressed into decorated cakes, dried, then ground to powder and whisked in a bowl — the practice Japan received and kept, and the reason chanoyu looks nothing like the way China drinks tea today. Cake tribute is conventionally said to have been abolished by imperial order at the start of the Ming, after which loose-leaf steeping displaced whisking on the mainland within a few generations. The gardens faded with the court that consumed them.

A village group in Mengku, Shuangjiang county, Lincang, and one of the most expensive sources of sheng pu-erh material in Yunnan. Bingdao’s old trees are Mengku large-leaf stock, and the tea made from them is characterised by very low bitterness, a thick sweetness and a strong returning sweetness in the throat — a profile at the opposite pole from Bulang. The prices attract a great deal of relabelled material from surrounding villages.

A mountain range in southern Xishuangbanna producing the most assertive sheng pu-erh in common circulation — strongly bitter young, with a pronounced returning sweetness, and the material most associated with long-term ageing potential.

A county on the western shore of Lake Tai in northern Zhejiang, and the site of Guzhu mountain — conventionally identified as the first dedicated imperial tribute tea garden, established in the Tang and producing the purple-budded Zisun or ‘purple bamboo shoot’ tea. Lu Yu lived in this area while compiling the Classic of Tea, and later writing credits him with recommending Guzhu leaf to the court; the attribution is repeated in every account of the garden and is not independently evidenced. Production lapsed for centuries and Zisun was reconstructed in the 1970s from the historical descriptions, so the modern tea is a revival rather than a survival.

Two low hills — East Mountain and West Mountain — on and beside Lake Tai in Jiangsu, and the home of Bi Luo Chun. Tea here is traditionally interplanted among loquat, plum, apricot and peach rather than grown in clean rows, and the fruit-blossom character growers claim for the tea is credited to that intercropping. The lake moderates temperature and holds morning mist over the slopes, which suits a very early, very small plucking.

A Guizhou prefecture producing Duyun Mao Jian, a downy curled green tea from a province that grows a great deal of tea and exports most of it anonymously into other regions' blends.

A Sichuan mountain producing Zhu Ye Qing and a range of other early greens. Its tea benefits from the same fog and mild winters as neighbouring Mengding, with harvests among the earliest in China.

A mountainous prefecture in western Hubei and the home of Enshi Yu Lu, the last steamed green tea made at scale in China. The steaming tradition survived here after pan-firing displaced it almost everywhere else.

The Lincang county where Yunnan black tea was invented rather than inherited. Dian Hong is conventionally dated to 1939 and credited to Feng Shaoqiu, who applied gongfu black-tea method to Yunnan’s large-leaf assamica after the war cut China’s established black-tea districts off from the export trade — an origin story that is specific, recent and repeated consistently, though TeaHQ has not verified it against a primary document. The local Fengqing Da Ye Zhong is a broad-leaved, heavily budded plant, which is why Dian Hong carries so much golden tip. The county also holds the Xiangzhuqing tree, one of the very old cultivated tea plants Yunnan uses to argue its case as a domestication centre.

A north-eastern Fujian county that matters less for a single famous tea than for the plants it supplied to everyone else. Fu’an holds the province’s tea research institute, and the cultivars selected and bred here — Fu’an Da Bai Cha and the Fuyun series among them — were propagated across Fujian and well beyond it, which is why a great deal of Chinese white and black tea traces its plant material to this one county. Tanyang, the village behind Tanyang Gongfu, sits inside it, and the county was a significant node in the nineteenth-century black-tea export trade through the Sandu’ao anchorage.

The coastal northern Fujian county most associated with white tea, and the home of the Da Bai cultivars whose heavy bud down gives Silver Needle its appearance and its name.

The Fujian capital, historically the great tea port of the clipper trade and still the centre of jasmine scenting. Jasmine is grown on the sandy flats along the Min river and picked in the afternoon; the flowers are held until they open after dark, layered with tea overnight and screened out at dawn, and the cycle is repeated — five, seven, nine times for the better grades. Fuzhou is a processing region rather than a growing one, and the distinction matters: the leaf usually comes from elsewhere in Fujian.

The Anxi township that drove the style most drinkers now think Tie Guan Yin simply is. From the 1990s growers here pushed processing toward minimum oxidation and a short, cool shaking — the so-called xiao qing or ‘sour’ handling — producing an intensely floral, pale green, almost unroasted oolong that photographed and shipped well and sold nationally. It made the county rich and then damaged its reputation, because the style is thin-bodied, fades quickly and does not keep. Gande sits higher and cooler than Xiping, which is part of why the aroma-forward reading works here at all.

A mountain in Menghai holding what is generally described as the largest continuous area of old planted tea in Xishuangbanna, spread across a run of Lahu villages including Manmai and Manghong. The layout is the interesting part: the trees stand inside the villages and among the houses rather than in separate gardens, so the settlement and the tea planting are physically the same thing — an arrangement that predates the plantation model and shows what ‘garden’ meant before rows. The tea is conventionally read as a middle position among Menghai origins: bitter on entry, sweet behind it, without Lao Ban Zhang’s extremity.

A county in Guangxi on the Yu river, and the reason jasmine tea is only half a Fujian product. Almost none of the jasmine used in Chinese scenting is now grown around Fuzhou; the flowers come overwhelmingly from Hengxian, where the hot, humid subtropical climate and long flowering season suit Jasminum sambac and where the crop has been planted at very large scale since the 1980s. Fuzhou remains a scenting and finishing centre — the workshops, the tea base, the multi-cycle technique — but the raw material arrives from six hundred kilometres away, and increasingly the scenting happens in Guangxi too.

The mountain range in southern Anhui that gives its name to Huangshan Maofeng and sits beside the Qimen county that produces Keemun. Persistent cloud and a short growing season produce small, tender leaf with a pronounced orchid aroma.

A county in the Dabie mountains of western Anhui, and one of the few places where yellow tea is still made as a living commercial practice rather than a revival. Huoshan Huangya takes a fine bud pluck through the men huang smothering step that defines the category; the coarser Huang Da Cha from the same county uses mature leaf and a heavy bake, and tastes almost nothing like it. Having both from one district is what makes Huoshan useful for understanding yellow tea at all.

A county in Pu’er prefecture whose local Jinggu Da Bai Cha cultivar carries an exceptionally heavy coat of white down on the bud, and the home of Yue Guang Bai — ‘moonlight white’. That tea is made by withering large-leaf Yunnan material indoors, away from sun, so the upper surface of the leaf darkens while the downy underside stays pale and the finished leaf is two-toned. Whether it counts as a white tea or a lightly worked pu-erh raw material is genuinely disputed in the trade, and Jinggu is where the argument starts.

A Lancang mountain area known for very old tea gardens interplanted with forest, and for a distinctly floral, orchid-scented sheng that is unusual among pu-erh origins.

A Shaanxi county far outside the tea-growing belt that nonetheless became the traditional pressing centre for Fu Zhuan brick tea, on the theory that local conditions favoured the fungal bloom. Production later moved to Anhua.

A small island in Dongting Lake, Hunan, and the sole origin of genuine Junshan Yinzhen yellow tea. The growing area is measured in hectares rather than square kilometres, which is why almost everything sold under the name is not from here.

A village on Bulang Mountain whose sheng pu-erh commands the highest prices in Yunnan. Its reputation rests on an aggressive bitterness that resolves into an unusually strong returning sweetness.

A granite coastal massif east of Qingdao in Shandong, planted with tea only from the 1950s under the state programme that moved southern tea north. It is close to the climatic limit for the plant: bushes are often covered through winter, growth is slow, and the season is short. Growers and drinkers describe the resulting green tea as unusually thick and bean-like, and attribute it to the cold and the long dormancy.

One of the three principal pu-erh prefectures of Yunnan, and the source of Bingdao and Xigui among others. Lincang material is typically brisker and more floral than Menghai’s, with a faster-arriving sweetness.

A village in Raoping county, east of the Phoenix range, and a useful corrective to how dan cong is usually explained. Lingtou Dan Cong is not a single-tree tea: it descends from one bush selected here in the 1960s, propagated by cutting and planted out as a conventional cultivar across the county and beyond. So the name behaves like Yabukita or Jin Xuan rather than like Song Zhong — a clone with a consistent honey-and-orchid aroma, grown at scale and priced accordingly. The two models sit side by side in eastern Guangdong under nearly the same word.

The Anhui prefecture behind Liu An Gua Pian, the only well-known Chinese green tea made from a single mature leaf with the bud and stem deliberately removed. It also gives its name to Liu An basket tea, a dark tea from the same area.

A Jiangxi mountain famous for Lu Shan Yun Wu — literally 'cloud and mist' — where near-constant cloud at altitude slows growth and produces a notably sweet, low-astringency green tea.

One of the six ancient tea mountains east of the Mekong, sitting between Yiwu and Yibang in Mengla county. It kept more of its old planting than either neighbour — the area saw less of the nineteenth-century upheaval and fire that stripped Yibang — so old-tree material here is comparatively less scarce than the reputation of the six would suggest. The tea is usually described as denser and firmer in the mouth than Yiwu’s, with more grip and less immediate sweetness, and it is one of the few of the six that can still be bought without a name premium doing most of the work.

The largest single producing village inside the West Lake Longjing area, occupying a long valley west of the lake and accounting for far more planted ground than Shifeng does. Its tea is conventionally described as the greener, fresher, more vegetal reading of Longjing — less of the toasted note, more bean and fresh grass — which growers attribute to a cooler, damper valley and a slightly different firing habit. Because the village is easy to reach and sells directly to visitors, Meijiawu is also where most people who have bought Longjing at source have bought it.

A county in northern Guizhou that became a centre of Chinese tea science when the national tea research station relocated there during the Second Sino-Japanese War, and which has since been planted very heavily as part of a provincial expansion programme. Guizhou’s combination of altitude, low sunshine hours and persistent cloud gives a soft, sweet green tea, and Meitan is where that provincial style is most consciously developed.

A Sichuan mountain with one of the longest continuous tea-cultivation records in China, producing both Meng Ding Gan Lu green tea and Meng Ding Huang Ya yellow tea. Cloud cover here is close to permanent.

The county at the centre of pu-erh manufacture, home to the factory where wet-piling was industrialised in the 1970s. Menghai-style shou is the reference point most other ripe pu-erh is described against.

A valley in Shuangjiang county, Lincang, running north to south with tea villages strung along both flanks — the East Half Mountain and the West Half Mountain, which local buyers price as distinct sources. The west side, holding Bingdao and its neighbours, is the expensive one; the east side is cheaper and generally read as brisker and more astringent. Above both stands the Da Xue Shan wild tea forest, a stand of very old large-leaf trees at high altitude that is protected and only lightly picked. Mengku Da Ye Zhong, selected here, is one of the national cultivars behind a great deal of Yunnan production.

A high mountain area in Menghai county with old tea gardens held by Lahu villages, of which Naka is much the best known. Naka’s sheng is described in the trade by a specific note — a cool, green, bamboo-shoot character over a firm bitterness — that buyers use to identify it, and the village’s output is small enough that most tea sold under the name is not from there. Two places in Xishuangbanna are called Mengsong, one in Menghai and one in Jinghong; the Menghai one is the one that matters for pu-erh.

The hills around the Jiangsu capital, and the home of Yuhua tea — a straight, dark, pine-needle-shaped green rolled by hand into strands rather than flattened or curled. Yuhua is worth recording precisely because it is not ancient: it was worked out at a provincial research institute in the late 1950s and named for the Yuhuatai district, which makes it a documented example of a ‘famous tea’ deliberately created in the twentieth century. Chinese green tea is full of these, and the catalogue usually cannot tell them apart from inherited ones.

One of the best known of the Menghai-area pu-erh mountains, with substantial stands of old arbour tea. Its material is typically balanced rather than extreme — neither as bitter as Bulang nor as soft as Yiwu.

A range in eastern Guangdong where oolong is made from individual named trees rather than blended stock, producing the aromatic single-bush teas known collectively as Dan Cong.

A district near Shaoxing in Zhejiang and the historic home of gunpowder tea, where leaf is rolled into tight pellets that survive long sea voyages far better than open-leaf green tea does. The style exists because of the export trade: pellets pack densely, resist crushing and hold their aroma, which is why gunpowder became the green tea North Africa adopted. Shaoxing’s river network carried the tea to Ningbo for shipment.

The Yunnan prefecture that gives pu-erh its name, formerly called Simao. Historically it was the trading and pressing centre rather than the main growing area, which is why the name describes a process and a place at once.

A county in southern Anhui whose black tea, made only from the late nineteenth century onward, became the aromatic backbone of English breakfast blends under the anglicised name Keemun.

The larger of Shandong’s two tea districts, on the coast south of Qingdao, and part of the same twentieth-century northward transplantation. The wide day-to-night temperature swing and the short season produce a thick-leaved, robustly roasted green tea with a pronounced chestnut character — very different from the delicate spring greens of Jiangnan, and the reason Rizhao developed its own market rather than competing with them.

The county that explains why Longjing is everywhere. Shengzhou sits in the old Yuezhou tea district of eastern Zhejiang, praised in Tang writing, and is today the largest producer of flat, blade-shaped green tea in China — most of it machine-pressed rather than hand-pressed against a wok wall, and most of it sold as ‘Longjing’ of one designation or another, legitimately as Zhejiang Longjing or otherwise. The county is also a major source of the roasted green leaf that goes for jasmine scenting and for export. It is the clearest case in Chinese tea of a famous name whose supply comes overwhelmingly from somewhere other than the place it is named after.

The highest and most expensive of the West Lake Longjing sub-areas, on the slope above Longjing village. Growers explain the premium by the ground: thinner, stonier, more freely drained weathered soil than the flats below, which slows the bush and delays bud break by several days — so Shifeng leaf is smaller, denser and picked later than lakeside tea sold under the same name. The finished cup is the toasted-chestnut, thick-bodied reading of Longjing rather than the grassy one. The eighteen bushes below Hugong temple, which tourist accounts credit to a Qing emperor’s visit, are a shrine rather than a source: the story is repeated everywhere and evidenced nowhere.

A county in the mountainous south-west of Zhejiang built around one of China’s largest wholesale green-tea markets, where growers from across the region sell fresh leaf daily through the spring. Its own Song Yang Yin Hou is a downy, curved-leaf green named for its resemblance to a monkey’s paw. Songyang matters less for a single famous tea than for showing how much of the Chinese green-tea trade actually moves: through regional wet markets rather than named estates.

A county in southern Anhui producing Taiping Houkui, whose enormous flat pressed leaves are unlike anything else in Chinese green tea. The local Shi Da cultivar and the pressing step are both specific to this small area.

A village in Fu’an, northern Fujian, and the origin of Tanyang Gongfu — one of the three historic Fujian gongfu black teas and a significant export tea in the late nineteenth century.

A steep, forested range on the Zhejiang–Anhui border, protected as a reserve and known for old-growth cryptomeria as much as for tea. The gardens sit among broadleaf forest at moderate altitude with persistent cloud, and the tea — Tianmu Qing Ding among them — is a sweet, clean, orchid-leaning green with the slow-grown character the range’s cool summers produce.

A narrow, high, forested valley inside the Wuyishan nature reserve, and the documented birthplace of black tea. Zheng Shan Xiao Zhong was made here long before it was made anywhere else, traditionally withered and dried over pine in a multi-storey smoking loft — the source of the smoke that Europe came to know as Lapsang Souchong. Access restrictions and the reserve’s protected forest keep production small, and the local unsmoked style, including the Jin Jun Mei made from buds, now commands far higher prices than the smoked one.

The river town at the centre of old Huizhou in southern Anhui, and the assembly point for Tunlü — the refined green tea that left China in enormous quantity for North Africa and Europe. Tunxi was a sorting, refining and grading centre rather than a garden district: leaf came in from the surrounding counties, was re-fired, screened by size and blended to a buyer’s specification, and left downriver. The distinction between where tea grows and where it is finished is one the export trade made constantly, and this is the clearest Chinese example of the second kind of place.

A mountain in Ningxiang county, Hunan, whose Weishan Maojian is one of the few Chinese green teas finished over smoke. The leaf is fixed and shaped conventionally and then dried over smouldering maple or pine, giving a resinous edge that sits over an otherwise sweet green base — a genuinely different use of smoke from the pine drying applied to Tongmu’s black tea.

A coastal southern Zhejiang prefecture whose tea reputation rests on timing. The Wu Niu Zao cultivar, selected from a Yongjia village population, buds exceptionally early — often in the second half of February — and the region supplies the first Chinese green tea of the year to a market that pays steeply for it. Wenzhou is also the home of Wenzhou Huangtang, a rare surviving yellow tea from the same district.

The high peak of the Phoenix range in Chaozhou, and the source of the oldest and most expensive dan cong. The distinguishing practice is that the trees are individuals: tall, single-trunk, seed-grown plants standing metres apart, each picked, withered and roasted separately and sold under its own aroma name. The Song Zhong lineage — trees held by local account to descend from Song-era plantings, a dating repeated locally and not independently established — comes from these slopes. Because a tree is a tree rather than a field, supply is measured in kilograms and almost everything sold as Wudong dan cong is cuttings grown lower down.

A mineral-rich mountain area in northern Fujian, home to the roasted 'rock teas' (yancha) and to some of the most heavily imitated tea names in the world.

A north-eastern Jiangxi county historically counted with Anhui’s Huizhou tea district rather than with Jiangxi, and a major source of the green tea that left China through the nineteenth-century export trade. Its Wuyuan Ming Mei is a slender, downy spring green; the county’s terraced hills, heavy mist and preserved Huizhou villages are part of why the area retained a distinct tea identity after administrative boundaries moved.

The Guangxi prefecture producing Liu Bao, a dark tea traditionally aged in bamboo baskets and shipped to South-East Asian mining communities. Its ageing tradition runs parallel to pu-erh’s rather than deriving from it.

The most remote of Anxi’s three principal Tie Guan Yin townships, high in the county’s western hills, and the one the domestic trade associates with body rather than aroma. Xianghua tea is conventionally described as thicker in the mouth with a slower, longer returning sweetness and less immediate floral lift than Gande’s — a distinction buyers make routinely and price on. The usual explanation is a combination of altitude, later picking and a slower, more traditional handling of the leaf, though the three are hard to separate.

A small village on the Mekong in Linxiang district, Lincang, growing at markedly lower elevation than most prized pu-erh areas — the gardens run down almost to the river. The tea is known for an intense, penetrating aroma and a fast, sharp mouthfeel rather than the broad sweetness of Bingdao, and the low-altitude riverside setting is the usual explanation offered for the difference.

The hills west of Hangzhou that produce Longjing, and the most tightly policed tea name in China. Within the protected area the sub-villages are themselves ranked — Shifeng, Longjing, Yunqi, Hupao, Meijiawu — with Shifeng’s thin, weathered stony soil conventionally rated highest and priced accordingly. The tea is pan-fired by hand against the wall of a heated wok, which is where the flat blade shape and the toasted-chestnut note both come from.

A Henan prefecture at the northern limit of viable tea cultivation in China, producing Xinyang Mao Jian. The cold winters and short season give a thin, intensely fresh leaf with a sharper character than teas from further south.

The township in southern Anxi where Tie Guan Yin is conventionally said to have originated, and where the older, heavier version of the tea survived the industry’s swing to light green oolong. Both of the competing origin stories — the farmer Wei Yin and his neglected shrine, the scholar Wang Shirang and his gift to the emperor — attach to villages here, and both are repeated everywhere without being evidenced. What is checkable is the style: Xiping makes Tie Guan Yin with more oxidation and a real charcoal roast, giving a darker liquor, a fruit-and-caramel register rather than a floral one, and leaf that ages rather than fading.

The southernmost Yunnan prefecture and the heartland of pu-erh, containing both Menghai and the six famous tea mountains of the Yiwu area. Almost every well-known pu-erh production area sits inside it.

A north-western Jiangxi county in the Xiushui river valley, historically known as Ningzhou and the source of Ning Hong — among the earliest of China’s gongfu black teas and a significant nineteenth-century export. The same county produces Gou Gu Nao, a downy spring green from higher slopes. Ning Hong’s prominence faded as Keemun rose, which is why a tea once traded across Europe is now barely known outside China.

The Sichuan city at the start of the historic tea-horse road to Tibet, and still the main producer of Kang Zhuan brick tea made for the Tibetan market.

A small town in Chibi, southern Hubei, and the manufacturing heart of the overland tea trade to Russia. Leaf from the surrounding hills was steamed and pressed here into the green bricks — qing zhuan — that travelled north by cart, camel and river through Kyakhta on the Mongolian frontier, a route that carried a large share of Russia’s tea for well over a century. Russian merchant houses established mechanised pressing here and at Hankou in the second half of the nineteenth century, which is unusual: foreign capital rarely reached back this far into Chinese production. The stone-paved main street, worn by barrow wheels, survives.

One of the six ancient tea mountains east of the Mekong in Xishuangbanna, and the administrative centre of the Qing-era tribute tea trade before Yiwu eclipsed it. Yibang is unusual among pu-erh areas for its small-leaf material, which yields a lighter-bodied, distinctly aromatic sheng rather than the broad power associated with large-leaf stock. Much of the old planting was lost to nineteenth-century unrest and fire, so surviving old-tree material is scarce.

A southern Sichuan prefecture at the confluence of the Min and Yangtze, and one of the earliest tea districts in China each spring — mild, low-lying and often picking before Zhejiang has begun. It supplies both very early green tea and the Chuanhong gongfu black that Sichuan sends into the export trade, and the early-market advantage is a large part of the region’s commercial identity.

The Hubei prefecture at the mouth of the Yangtze gorges, and the collecting point for Yi Hong gongfu black tea drawn from the surrounding mountains. Its importance was as much logistical as agricultural: Yichang was a treaty port and transhipment hub, so tea from a wide inland catchment acquired the port’s name in the export trade. The tea itself is sweet and gently malty, made from small-leaf local stock.

A northern Guangdong county whose black tea industry was created deliberately in the late 1950s as a state project, planted with large-leaf material rather than the local small-leaf population. The signature cultivar, Yinghong No. 9, gives a dark, thick, cocoa-and-malt liquor that stands up to milk — which was the point, since the tea was developed with export and blending markets in view. It is one of the clearest cases in China of a regional style being engineered rather than inherited.

A mountain area in eastern Xishuangbanna and one of the six historic pu-erh tea mountains, known for gentle, sweet, honeyed sheng with comparatively little bitterness — the soft end of the pu-erh spectrum.

A Jiangsu county on the other side of Lake Tai from Changxing, known to the Tang as Yangxian and supplying tribute tea alongside Guzhu across the provincial boundary. Its modern fame rests on the clay rather than the leaf: the zisha stoneware pressed and fired here from the Ming onward is the vessel that made small-pot gongfu brewing possible, and the unglazed, slightly porous body is why the pots are traditionally dedicated to a single tea. Tea is still grown on the same hills — mostly green, with a local black — but the county’s contribution to tea is a piece of equipment.

A Fujian county producing Fo Shou oolong from an unusually large-leaf cultivar. It sits outside the better-known Anxi and Wuyi areas and its tea is correspondingly under-recognised — and, because Fo Shou is charcoal-roasted as a strip oolong the way Wuyi teas are, is sometimes sold as though it came from there.

The westernmost of the six ancient tea mountains and the only one lying outside Mengla county, in what is now Jinghong. It is the mountain of the Jinuo, a small people officially recognised only in the late 1970s, whose tea use includes a fresh-leaf salad as well as the sun-dried maocha the pu-erh trade buys. Youle sits lower and warmer than most of the celebrated Banna origins, and its material is read as brisk and slightly sharp — never the prestige tier, which is part of why old planting here survived being picked over.

A county in western Hubei responsible for Yuan’an Lu Yuan, one of the small handful of yellow teas still produced. The tea is made from a spring pluck given the smothering step that converts a green tea into a yellow one, and it survives largely because a local co-operative tradition kept the method alive when yellow tea nearly vanished commercially in the twentieth century.

A small lakeside tea area in Yueyang on the north-eastern shore of Dongting Lake, taking its name from the Beigang — a river a little over two kilometres long that rises at Meixi and is called the north harbour because it lies north of the Nangang. Gardens sit at Beigang itself and in Kangwang township of Yueyang county, on flat ground interlaced with water beside the lake the Tang called Yonghu and modern maps call Yangjia. The agronomically interesting feature is the mist: on early spring mornings vapour lifts off the lake and drifts across the gardens on the north bank, which is the local explanation for a yellow tea made here rather than a green one. The soil is fertile and suitably acid, and the ground is flat — unusual for a Chinese famous-tea district.

A south-western Chinese province with large-leaf assamica stock and old tea trees, and the origin of both pu-erh and the golden-tipped black tea sold as Dian Hong.

A Fujian county producing Zhangping Shui Xian, the only oolong traditionally pressed into small paper-wrapped squares. The format is local, old, and found nowhere else in the category.

The inner scenic area of the Wuyi massif, and the reason Wuyi oolong is priced by where it grew rather than by which bush it came from. The trade divides the mountain into three bands — zheng yan, the gardens inside the cliffs; ban yan, the ‘half rock’ hills around them; and zhou cha or wai shan, the riverside flats and outer country — and the same cultivar picked and roasted the same way sells for wildly different money across those lines. The most sought plots are the ‘three pits and two ravines’: Huiyuan Keng, Niulan Keng, Dakeng Kou, Liuxiang Jian and Wuyuan Jian. What they share is not altitude but shape: narrow, north-facing clefts where direct sun lasts a few hours, water seeps continuously from the rock face, and centuries of leaf litter and cliff debris have collected on the floor.

An inland northern Fujian county producing white tea in a fuller, darker style than coastal Fuding, using its own Da Bai cultivar and a longer indoor wither.

The tea district of southern Jiangsu, on the hills and piedmont slopes of the Ning-Zhen and Maoshan ranges where they rise from the south bank of the Yangtze. Its tea is Jinshan Cuiya, a flat-pressed green named for the Jinshan temple, and the district matters agronomically for a reason that has nothing to do with fame: this is one of the northernmost places in China where tea is grown commercially, and the soils are explicitly transitional between the northern and southern types, running from loam to light clay. Growing tea at this latitude is a frost calculation as much as a soil one. The protected area is the whole of Zhenjiang's Runzhou, Jingkou and Dantu districts and its New Area, together with Danyang and Jurong.

A county on the Han river in the Qinba mountains of southern Shaanxi, near the northern edge of viable tea cultivation in China and a long way from anywhere else that grows it. Its selling point is geological: the local rocks are unusually rich in selenium and the tea is marketed on that composition, which is a claim about the leaf rather than about the drinker. Historically the district’s coarse leaf fed the border-trade brick industry — Ziyang material travelled north to the Jingyang pressing houses that made Fu brick for the north-western markets, which is how a Shaanxi county came to have a tea identity at all.

A cloud-forest valley on the western Andean cordillera above the Dagua river in Valle del Cauca, and the only place in Colombia where tea is grown at any scale. A single plantation established here in the middle of the twentieth century sits inside a private forest reserve, grows and processes its own leaf, and sells almost all of it within the country. The setting does the interesting work: near-permanent cloud at this altitude in the tropics gives the diffuse light and moderated temperature that tea generally does well in, on a continent where the plant is otherwise a curiosity.

A large plantation in the Kaffa highlands of south-western Ethiopia, cut out of the same wet montane forest that holds the country’s indigenous Arabica, and one of only a handful of places Ethiopian tea comes from. The site is a state-established block rather than a district of farms: there is no surrounding smallholder tea sector, no local tradition of growing the plant, and the crop is made as CTC for the domestic market. The name has also become attached, confusingly, to a coffee variety selected in the same area, which is not the tea.

The humid coastal province south of Batumi where Georgian tea began. Cultivation is conventionally dated to plantings at Chakvi in the 1890s, laid out under the direction of a Chinese specialist engaged for the purpose. Adjara has the wettest climate in the Caucasus and the plantings run right down toward the sea, which is why cultivation succeeded here before it was attempted further north. The botanical garden above Chakvi still holds part of the original collection.

A western Georgian province behind the Black Sea coast at Ozurgeti, and one of the main centres of the country’s tea revival. Many of its plantations were abandoned in the 1990s and have been reclaimed from twenty years of scrub, so the working bushes are old, deep-rooted and unsprayed by circumstance. Growers here have led the move from Soviet-style bulk black tea toward hand-processed black, green and white production.

The province north of the Rioni around Zugdidi, historically one of Georgia’s largest tea districts and among the hardest hit by the post-Soviet collapse and the conflicts of the 1990s. Recovery has been slower here than in Guria, and much of the planted area remains derelict — which makes Samegrelo the clearest illustration of what happened to Georgian tea rather than of what it is becoming.

A Tamil Nadu range south of the Nilgiris producing high-grown South Indian tea, including a growing amount of orthodox and speciality production.

The Indian frontier state north-east of Assam, where commercial planting began only in the 1990s in the low districts of Namsai, Lohit and Changlang. Agronomically this is the same Brahmaputra system as Upper Assam — the same assamica, the same monsoon — but the ground rises toward the hills and nights are cooler, and the state has pushed orthodox and speciality manufacture rather than trying to compete on CTC volume. It is the only place in India where a tea district is being built from scratch in the twenty-first century, with everything unsettled that implies.

A hot, low-lying river valley in north-east India and the only major tea region built on native assamica stock rather than introduced sinensis, giving the malty, deep-coloured tea the region is named for.

Southern Assam’s other river valley, draining west into the Surma and the Bengal delta rather than into the Brahmaputra, and effectively a separate origin sharing a state boundary. Cachar and Karimganj sit on the same low hillock country as Sylhet immediately across the international border, and their tea behaves accordingly — hot, low, monsoon-driven, made almost entirely as CTC and priced well below Brahmaputra leaf at auction. Selling Barak valley tea as ‘Assam’ is administratively correct and descriptively misleading, which is the reason to give the valley its own record.

The commercial centre of the Nilgiris, on the southern slope of the plateau below Ooty, and where South Indian tea is actually traded: the Coonoor auction is one of India’s main sale centres and handles a large share of the region’s crop. The surrounding gardens sit high on the plateau edge and include most of the district’s orthodox and speciality manufacture, as opposed to the CTC that dominates lower down. The winter frost teas the Nilgiris are known for — leaf picked after cold nights, in years when they come — are a Coonoor-belt phenomenon.

A hill district in Karnataka on the Western Ghats, better known for coffee, where tea occupies the higher and wetter ground alongside it. Gardens are frequently shaded and interspersed with spice and coffee planting rather than laid out as monoculture estates, and most output is CTC. The interest is agronomic: Coorg shows how tea behaves as a secondary crop in a landscape organised around something else.

A steep Himalayan district in West Bengal planted largely with sinensis stock, whose teas are sold by flush because the same garden produces genuinely different tea in spring, summer and autumn.

The flat, heavy-soiled plain east of the Teesta at the foot of the Bhutan hills, planted from the 1870s and now one of India’s larger producing districts. Gardens here are large, level and mostly CTC, and the tea is bright and full-bodied without the aromatic lift of the hill districts a few miles north. Its commercial role is to give body and colour to blends, which is why the name rarely appears on a packet.

A small Himachal Pradesh growing area in the western Himalaya, planted in the nineteenth century and largely destroyed by the 1905 earthquake. Its surviving production is tiny and its teas — light, aromatic and Darjeeling-adjacent — are rarely seen outside India.

India’s newest tea district, in the narrow neck of Bihar between Nepal, Bengal and Bangladesh, planted only from the 1990s on the same sandy Terai alluvium that carries the Darjeeling foothills. Its structure is what makes it interesting: there are essentially no estates, only smallholders with a few acres selling green leaf to bought-leaf factories, in a country whose tea industry was built on plantations and still assumes them. Kishanganj has no auction identity and no name recognition, and its leaf leaves the district anonymously into blends.

India's forgotten Himalayan tea district, and the clearest case in the country of an industry that was built, abandoned and then rebuilt from almost nothing. The gardens sit in the central Himalaya around Kausani, Berinag and Chaukori, on south-facing ridges looking straight at the high snow peaks — the same mountain system as Darjeeling five hundred miles east, at comparable altitude, planted in the colonial period with the same Chinese-derived stock. The plantings then lapsed for most of the twentieth century as labour and access made them uneconomic, and the surviving bushes went feral. What is made now is a deliberate revival on that old ground, orthodox and in tiny quantity.

The middle belt of the Darjeeling district, on the ridge running down toward the plains, and the band that carries a large share of the area’s best-known gardens. Kurseong sits lower and warmer than the Darjeeling and Mirik hills above it, which shows in the calendar and in the cup: the flushes arrive earlier, the second flush is fuller, and the muscatel character the district trades on is most consistently associated with this elevation. The valleys are conventionally split into a northern half, higher and cooler toward Darjeeling town, and a southern half dropping toward the Terai.

A hill state that grows tea without ever having had a plantation industry, which in India is close to unique. Planting is concentrated on the Khasi hills and in Ri-Bhoi on the northern slope toward the Assam plain, and it is smallholder from the ground up: plots of an acre or two, worked by families on community-held land under customary tenure that has no room for a thousand-hectare estate. A small number of independent gardens make orthodox tea here and sell it under their own names, which is the only route available to a producer with no auction identity to fall back on.

The western valley of the Darjeeling district, running along the Nepal border, and the part of the area that is hardest to tell apart from Ilam on the other side of the line — the same ridge system, the same plant material, the same weather. Its gardens sit high and cool, so bud break is late and the first flush arrives after Kurseong’s, and a good deal of the valley is planted with clonal China-hybrid selections made for aroma rather than with old seed stock. That combination is why Mirik gardens are strongly associated with the pale, green, floral style of modern first flush.

A high-elevation Kerala district in the Western Ghats, producing brisk South Indian tea at altitudes closer to Nilgiri than to Assam. Much of it goes into blends.

A high plateau in southern India that harvests through most of the year rather than in flushes, producing a clean, fragrant black tea widely used for blending and unusually resistant to clouding when iced.

The gardens on the far side of the Brahmaputra from the main Assam belt, running along the foot of the Arunachal hills through Sonitpur, Biswanath and Lakhimpur. The river is wide enough here to make this a genuinely separate district: the north bank gets more of its water off the hills and less off the monsoon plain, nights are cooler with the mountains close, and the trade reads its teas as brighter and more aromatic and less heavily malty than the south bank’s. It is also the part of the valley most exposed to Brahmaputra flooding and erosion.

The eastern flank of the Darjeeling district, dropping steeply to the Teesta river, and the warmest and lowest of the recognised valleys. Heat rising off the gorge advances the season here — Teesta Valley gardens are usually among the first in the district to flush — and the cup is correspondingly fuller and less delicate than the high western hills produce, closer in body to a foothill tea while still carrying the district’s aromatic signature. The valley is also the most landslide-prone part of a landslide-prone district, which affects access more than it affects the tea.

Sikkim’s only significant tea garden, established in the 1960s on a south-facing slope in the state’s southern district and run under state ownership. It sits at Darjeeling elevations on the same Himalayan system, is planted largely with sinensis stock and is managed organically, producing a light, muscatel-leaning orthodox black tea in very small quantity. Being a single garden rather than a district makes Sikkim tea unusually traceable.

The narrow belt of sandy alluvial land directly beneath the Darjeeling hills, west of the Teesta, where the plains meet the Himalayan foothills. Its teas are brisk and spicy with a distinctive edge that comes from being grown warm and low but on ground fed by hill drainage. Terai leaf is often blended with Darjeeling material, which is one reason the district’s own identity has stayed indistinct.

The one genuine gap in TeaHQ's Indian coverage, and a district that explains why a state can be a long-established producer and still have no name recognition at all. Tripura's gardens sit on tila — low, rounded lateritic hillocks a few tens of metres above the surrounding paddy — in a pocket of India almost surrounded by Bangladesh, on the same geological and climatic system as Sylhet a short distance west rather than as Assam to the north. The tea is made overwhelmingly as CTC, sold through the Guwahati auction, and disappears into blends. Nothing about the leaf is distinctive; what is distinctive is the industry's shape, which is a large number of very small gardens and a state corporation trying to hold them together.

The eastern end of the Brahmaputra valley — Dibrugarh, Tinsukia and Sivasagar — and where the Indian industry began. Tea is generally dated as having been found growing wild in this part of Assam in the 1820s and 1830s, and the first commercial gardens were laid out on that indigenous assamica rather than on Chinese seed, which is the reason Assam tastes the way it does and India’s tea industry looks nothing like China’s. Those gardens were established by British planters on land taken into the plantation system and worked by labour recruited under indenture from central India and held there by law — a history the valley’s demography still carries and one this record declines to leave out. Upper Assam gardens are on flat, hot, heavily watered alluvium and produce the maltiest, heaviest second flush in the valley; this is the band the tippy orthodox teas that carry the region’s reputation come from.

A Kerala plateau district growing tea alongside coffee and spice, at lower elevation than Munnar and giving a fuller, softer cup.

The plateau country around Lake Toba, in Simalungun and neighbouring districts, planted in the colonial period alongside rubber and tobacco. Estates here are large and long-established, growing assamica at moderate altitude in a wet equatorial climate, and the tea is fuller and earthier than Java’s. Its main outlet is orthodox black leaf for blending, where the body it carries is the reason it is bought.

The Priangan highlands south of Bandung, where Dutch planters concentrated tea after the early Chinese-seed experiments failed and assamica stock proved suited to the volcanic uplands. Gardens sit on the flanks of active volcanoes with rainfall spread across the year and no dormant season, so plucking is continuous. The resulting black tea is clean, brisk and slightly mineral, and much of the world’s scented and blended tea has passed through it unlabelled.

The Caspian province that holds most Iranian tea, on the wet northern slope of the Alborz where the mountains wring rain out of the sea air and produce a humid, temperate strip unlike anywhere else in the country. Lahijan is the centre and the site of the earliest plantings around the turn of the twentieth century. Gardens are small, terraced and hand-picked, and output is orthodox black tea for a domestic market.

The town in Gilan that Iranian tea is named after, and the place the industry was started from. The hillsides immediately above Lahijan are terraced in narrow steps up to the treeline, worked by hand in plots small enough to be measured in rows, and the tea made from them is the reference point Iranian drinkers use — 'Lahijan' on a packet functions the way 'Darjeeling' does, as the good version of the national product. The introduction of the crop is conventionally credited to a Qajar-era diplomat who brought planting material and method back from India around the turn of the twentieth century; his tomb above the town now houses the national tea museum, which tells you how central the story is to the town's account of itself.

The eastern half of Iran’s Caspian tea strip, and a good illustration of how a growing area ends. Rainfall on this coast falls steadily as you move east from Gilan, so the gardens concentrate in the western districts around Ramsar, Tonekabon and Chalus and thin out toward Sari and beyond — not because of a boundary or a policy but because the rain runs out. The plots are small, terraced and hand-picked as in Gilan, and the output is orthodox black tea for a domestic market that imports far more than the country grows.

A town in Shimo-Niikawa on the Niigata border, and the only tea-producing area in Toyama prefecture. Production is concentrated in the Hirudani hamlet and exists for one product: batabatacha, a mould-fermented dark tea drunk whisked to a foam at neighbourhood gatherings, and recorded in the district since around the fifteenth century. The agricultural year is unlike anywhere else in Japanese tea — the leaf is cut in late July, long after the flushes that matter elsewhere are over, steamed to stop the enzymes, then heaped for about forty days while a mould works through it, and sun-dried in early September. Not a district that grows tea and then decides what to make; a district whose entire tea calendar is set by one fermentation.

A narrow river valley at Okabe in Fujieda, Shizuoka, and one of the three districts that account for essentially all Japanese gyokuro alongside Uji and Yame. Shading here is still done in the traditional honzu manner over a good part of the crop — reed screens and loose rice straw laid over a frame, added in stages so light is cut gradually rather than at once — which is slower and dearer than the black synthetic cloth used elsewhere and produces a more diffuse shade. The valley is small, the output is tiny, and almost none of it leaves Japan.

A small mountain district in Shiga prefecture near Shigaraki, traditionally counted among Japan’s oldest tea areas and planted, by local account, from seed brought back from Tang China. Production is tiny, the plots are steep and the climate is markedly colder than the Uji basin over the ridge, giving a slow-grown leaf and a thick, aromatic sencha that trades on scarcity and on the district’s claimed antiquity.

The largest tea-producing municipality in Japan, on the Satsuma peninsula in southern Kagoshima, and the clearest expression of the modern Japanese model. The land is flat volcanic ash soil, the gardens are laid out for riding harvesters, and the cultivar mix is deliberately staggered — early-budding selections such as Yutakamidori first, Yabukita behind them — so that a single factory can run continuously through a long first-flush season instead of racing one variety. The tea is deep-steamed and blended, and Chiran leaf reaches drinkers under a great many labels other than its own.

The upper Abe and Warashina river valleys behind Shizuoka city — the prefecture’s original tea country, as the name (‘the true mountain’) implies. Gardens are steep, small and river-fogged, and the style is deliberately conservative: a light asamushi steaming that keeps the needle intact and leaves a clear, aromatic liquor, in contrast to the deep-steamed teas that dominate Shizuoka’s flatter districts.

A mountain village inside the Yame district of Fukuoka, and the focal point for Japan’s traditional hon-gyokuro. What the designation demands is method rather than place: shading with reed screens and straw rather than cloth, and hand-plucking rather than shears, on gardens grown as individual bushes instead of a trimmed hedge. Hoshino gardens take the top places in the national tea competition’s gyokuro class with a regularity that is itself the district’s reputation, and the quantities involved are very small.

Mie prefecture, marketed collectively as Isecha, is one of Japan’s largest producing areas by volume and is particularly associated with kabusecha — leaf shaded for a shorter period than gyokuro, which lifts sweetness without going all the way to the covered-garden style. The northern districts around Yokkaichi supply much of that kabusecha, while the southern valleys make conventional sencha; the prefecture’s scale means a great deal of blended Japanese tea contains Mie leaf without saying so.

Japan’s second-largest tea prefecture and its most modern, on the southern tip of Kyushu. Flat volcanic land allows full mechanisation, and the mild climate gives the country’s earliest shincha and a wide cultivar range.

A Shizuoka city on the eastern edge of the Makinohara country, closely identified with deep-steamed sencha and with an older land practice that goes with it. Strips of semi-natural grassland — chagusaba — are kept between and around the tea rows, cut by hand each autumn and spread as mulch; the practice conserves soil moisture and structure and has been recognised as an agricultural heritage landscape because the uncut strips carry grassland plants that have largely vanished from lowland Japan. It is one of the few places where a tea district’s biodiversity argument rests on what is not planted with tea.

A mountain town in Tokushima on Shikoku, and the home of Awa bancha — one of the few genuinely fermented teas made in Japan, and nothing like the rest of the country’s output. Mature summer leaf is stripped from the branch, boiled, rubbed to break the surface, then packed into wooden barrels with the boiling liquor, held under a stone and left for weeks while lactic-acid bacteria work on it; the leaf is then shredded and dried in the sun. The result is sour, cider-like and almost free of bitterness or astringency, closer to a pickle than to sencha, and it is drunk locally as an everyday tea rather than a curiosity.

The steep upper valley of the Ōi river in northern Shizuoka, and the prefecture’s counterweight to the plateau country downstream. Gardens are small, terraced and hemmed in by forest, and river fog sits in the valley through the morning, so the leaf grows more slowly and thinner than on Makinohara. Kawane consequently keeps to a light asamushi steaming that leaves the needle intact and the liquor clear, and its teas place repeatedly at the top of national competitions — the standard example, within one prefecture, of how differently the same species behaves on a slope and on a plain.

A volcanic upland straddling the Kagoshima–Miyazaki border, planted on deep ash soils at higher elevation than most of Kyushu’s tea. The name means ‘island of mist’, and the persistent cloud cover functions as partial natural shading. The district has an unusually high concentration of organically managed gardens and produces both steamed sencha and pan-fired kamairicha.

The flat tableland between the Ōi river and the sea in Shizuoka, and the largest continuous tea field in Japan. It was cleared and planted from the 1870s by former retainers of the deposed shogunate and by ferrymen put out of work when the river was bridged — a settlement scheme rather than an agricultural tradition, which is why the layout is regular and the whole plateau is machine-workable. The plateau is open and sunny with no valley fog, so the leaf grows thick and the liquor is coarse; deep steaming, fukamushi, was developed to deal with exactly that, breaking the cell structure down until the cup turns opaque green and soft. The style is a solution to a place.

A Kyushu prefecture known both for conventional sencha and for kamairicha, the pan-fired green tea that is the exception to Japan’s steaming rule.

The northernmost commercial tea district in Japan, on the Sea of Japan coast in Niigata, where heavy winter snow rather than frost is the limiting factor. Snow cover insulates the bushes through the dormant period; the season is short, yields are low and the tea is made almost entirely for a local market. It exists because a seventeenth-century local lord promoted planting, and it persists as a demonstration of how far north the plant can be pushed.

A city in Aichi prefecture on the alluvial flats of the Yahagi river, and the largest producer of tencha — the shaded, unrolled leaf that is ground into matcha. Nishio’s advantage is not altitude but soil and logistics: deep river-deposited soil, a mild coastal climate, and a concentration of grinding capacity that made it an industrial counterweight to Uji’s older reputation. Most matcha sold at everyday grades comes from districts like this rather than from the famous Kyoto gardens.

A town in the mountains of Kōchi on Shikoku, and the only place goishicha is still made. The process runs two fermentations rather than one: steamed leaf is heaped and left to grow a mould, then packed into a barrel under a stone for a second, lactic fermentation, then cut into small squares and dried on mats — the squares are what give the tea its name, after the black stones used in go. Two-stage fermentation of this kind is otherwise a mainland Asian practice, and it survives here in the hands of a very small number of households.

A district on the Kantō plain in western Ibaraki, small today and historically significant for one reason: Sashima tea is conventionally identified as the first Japanese tea shipped to the United States, dated to the opening of Yokohama in 1859 and credited to a local grower who had organised production for export. The attribution is standard in Japanese accounts and is recorded here as such rather than as verified. The district’s style is heavily fired, giving a dark, roasted, strongly aromatic sencha quite unlike the light Kansai idiom.

Saitama’s tea district and the northern edge of commercial cultivation in Japan. Cold winters produce thicker leaves, and the local sayama-bire finishing fire gives the tea a distinctly toasty character.

Japan’s largest tea-producing prefecture by planted area and the home of the Yabukita cultivar, supplying much of the everyday sencha and bancha drunk in the country.

A low island off the southern tip of Kyushu, and the earliest commercial harvest in Japan — leaf is commonly cut here in the second half of March, weeks before the mainland. The reason is straightforward: the island is warm, effectively frost-free and low-lying, so bud break comes early, and growers plant very early cultivars to widen that advantage further. The premium is entirely about date. Shincha is a market that pays for being first, and Tanegashima exists in the Japanese tea calendar because it can be.

A small, historically prestigious growing area south of Kyoto, closely associated with shaded teas — gyokuro and high-grade matcha in particular.

A small town in the hills south-east of Uji, and the place the modern sencha method is conventionally traced to. The account, repeated in every Japanese history of the drink and not verified here against a primary document, credits Nagatani Sōen with working out in the 1730s a way of steaming, rolling and drying ordinary green leaf into a needle that would infuse clear and green — where everyday tea until then was largely brown, pan-scorched or boiled, and the fine bright stuff was powdered tencha for the tea ceremony. Almost every Japanese green tea drunk today descends from that method rather than from the ceremony.

A district in Saga prefecture, Kyushu, and the heart of Japan’s pan-firing tradition — the exception to the national rule that Japanese green tea is steamed. Kamairicha here is fixed in a heated drum or pan rather than by steam, giving a rounder, nuttier, less marine cup and a curled rather than needle-shaped leaf. The technique arrived from China through Kyushu’s trading ports and survived in pockets after steaming became standard elsewhere.

A steeply terraced town in southern Kyoto producing a large share of what is sold as Uji tea. Its hillside gardens supply much of the tencha destined for high-grade matcha.

The upland east of Nara around Tsukigase and Yamazoe, where tea is grown on a cold plateau at the northern edge of what Kansai considers workable. Much of the crop is tencha and kabusecha rather than open-grown sencha, and much of it is sold into the Kyoto trade — which means Nara leaf routinely reaches drinkers ground into matcha labelled Uji, because Japanese regional tea names describe a blending and finishing area rather than a field. Yamato is a good place to notice that convention, since the prefecture next door gets the credit.

A Fukuoka district producing some of Japan’s most highly regarded gyokuro, made under long shading in a river valley whose fog reduces the need for artificial cover.

The county immediately south of Kericho on the same Rift plateau, at the same altitude and under the same rainfall — and organised the other way round. Where Kericho’s landscape is dominated by very large multinational estates with their own factories, Bomet’s tea is overwhelmingly smallholder, delivered as green leaf to factories owned through the growers’ agency. Put side by side, the two counties are the clearest illustration available of the two structures that produce Kenyan tea, with the agronomy held constant and only the ownership changing.

The centre of Kenyan tea production, a high plateau near the equator with rainfall spread through the year. It is the reason Kenya harvests continuously rather than seasonally.

A densely populated highland district in south-western Kenya where tea is grown on very small family plots rather than estates, and delivered daily to factories run through the smallholder agency. It is the clearest example of the structure that actually underlies Kenyan tea: most of the national crop comes from holdings of a hectare or less, not from the plantation landscape the country is usually pictured as.

The highland district north-west of Nairobi where Kenyan tea started, on the regulator’s own chronology, with seed planted at Limuru in 1903. It is the coldest of the Kenyan growing areas — high, wet and prone to hail — and its bushes grow noticeably more slowly than the Rift plateau’s, which growers offer as the reason for a brighter, thinner liquor. The district’s working problem is not agronomic: it sits directly in the path of Nairobi’s expansion, and tea land here competes with housing in a way it does not anywhere else in Kenya.

The tea belt on the eastern and northern flanks of Mount Kenya, east of the Rift and climatically distinct from the plateau districts: rainfall arrives in two distinct seasons rather than being spread through the year, so cropping here has more of a rhythm than Kericho’s continuous plucking. Production is almost entirely smallholder around a set of agency factories, and Meru is one of the areas where orthodox manufacture and the anthocyanin-rich purple cultivars have been pushed as an alternative to competing on CTC volume.

A Kenyan highland district north of Kericho, growing at similar elevation and producing a slightly brighter, more aromatic leaf that increasingly goes into orthodox rather than CTC production.

A high-altitude smallholder district on the western slopes of Mount Kenya, east of the Rift and climatically distinct from the Kericho plateau. Its cool nights and deep volcanic soils suit the anthocyanin-rich purple cultivars the Kenyan research service released, and Nyeri has become one of the areas where those and other speciality clones are grown for orthodox rather than CTC manufacture.

A basalt plateau in southern Laos, raised above the Mekong plain and planted by French colonial concessionaires in the 1920s and 1930s with coffee, and with tea alongside it. The lineage is entirely different from northern Laos: these are planted rows of introduced stock rather than old forest trees, the altitude is moderate, and the volcanic soils and cooler plateau climate are the same ones the region’s coffee reputation rests on. Tea remains the secondary crop here and always has been.

Laos’s northernmost province, wedged against Yunnan and Vietnam, and the country’s significant tea area. Old, tall, seed-grown tea trees stand in and around Phunoi and Akha villages — the gardens at Ban Komaen are the best known — and are worked by climbing rather than by plucking from standing, in exactly the way the Yunnan side of the border does it. Most of the leaf is sun-dried into maocha and sold north, where it is pressed and sold as Chinese material, so Phongsaly’s tea largely reaches drinkers as somebody else’s origin.

The only tea district in Madagascar, on the eastern escarpment a short distance from Fianarantsoa, where the highland plateau breaks down toward the rainforest belt and the coast. The estate sits beside a lake on the old forest railway line that runs to the sea, and the siting is the point: this is the narrow band where highland altitude meets escarpment rainfall, cool enough to slow the bush and wet enough to keep it growing. Nowhere else on the island combines the two at a scale anyone has tried to farm.

The district on the flanks of Mount Mulanje in southern Malawi, and with neighbouring Thyolo one of the two areas that carry the country’s tea industry. The massif forces orographic rainfall onto its south-eastern slopes, which is why tea is viable here and not on the drier plains below. Most output is CTC, but Mulanje estates also supply much of Malawi’s small speciality white and hand-rolled production.

The southern Malawian district where African tea cultivation began in the 1880s, and still the country’s main producing area. Most output is CTC for blending.

A montane plateau in Pahang, cleared for tea from the late 1920s and still the source of almost all Malaysian production. At around 1,500 metres the climate is cool and permanently humid with year-round growth, and the steep terraced gardens are harvested by hand shear and by machine. The tea is a straightforward brisk black leaf built for milk and sugar, which is what the domestic market wants.

The tea plateau of southern Mauritius, and effectively the whole of the island's industry. The gardens sit on the cool, wet interior uplands in the Savanne district, on deeply weathered lateritic soil that sugar cane never wanted — which is precisely why tea is there. The estate runs its own factory and a visitor route, and the great majority of what it makes is flavoured with vanilla before sale. That last fact is the honest headline for the district: the leaf is competent, the vanilla is what the market buys, and describing the terroir without saying so would misrepresent the product.

The tea district of Zambézia province, on the wet southern flank of Mount Namuli, where Portuguese planters laid out very large estates from the 1920s and built a company town to run them. By the middle of the twentieth century this was among the biggest tea areas in Africa. Independence and the civil war ended that: factories were wrecked, gardens abandoned, and bushes grew out into thickets that later replanting has had to cut back to. Gurué is the clearest African example of a tea landscape that outlived its industry, and of how long the ground remembers a plantation.

The tea mountain of the Palaung, and the single most important tea place in Myanmar. Namhsan sits on a high ridge in northern Shan State, and the settlement runs along the crest with tea gardens dropping away on both sides — a landscape shaped entirely by one crop, worked by one people, for long enough that the local polity's wealth was tea revenue before it was anything else. Two quite different products come off the same bushes: dried leaf for brewing, and leaf steamed and packed to ferment into laphet, the pickled tea eaten as a salad that is a Burmese national dish rather than a drink. A place where tea is food as well as beverage is rare enough to be the record's reason for existing.

The eastern Myanmar uplands, contiguous with the Yunnan and northern Thai tea country and holding the same old large-leaf stock. Leaf from here goes two ways: to conventional green and black manufacture, and to the pits and vats where it is steamed, packed under weight and fermented into laphet for eating. The dual use has kept old, tall, seed-grown tea trees in production long after they would have been replaced elsewhere.

An eastern Nepali district whose gardens sit at Darjeeling-like elevations and grow largely Darjeeling-derived cultivars. Its orthodox teas are among the closest in character to Darjeeling produced outside India.

The main tea district of eastern Nepal, sharing a ridge system and a growing season with Darjeeling immediately across the border, and producing teas that are frequently mistaken for it.

Nepal’s lowland tea district in the far south-east, on the plains adjoining the Indian Terai, and the source of most of the country’s tea by volume. Almost all of it is CTC grown on flat land and sold into India for blending — the exact opposite of the orthodox hill teas that give Nepal its speciality reputation. The two sectors share a country and almost nothing else.

An eastern Nepali hill district adjoining Ilam, where tea is grown almost entirely by smallholders on terraced plots and processed at co-operative factories. Because growers deliver leaf rather than manage estates, the character of a Panchthar tea is set at the factory as much as in the field, and the district’s output ranges from Darjeeling-style orthodox black to green and white production from the same gardens.

Flat pasture country north of Hamilton on New Zealand’s North Island, planted with Taiwanese oolong cultivars from the 1990s in what is the country’s only commercial tea. Everything about the operation is a response to a climate the plant was not bred for: a shelter belt of thousands of trees around the block to break the wind, hand-plucking because the volume is small, and a season limited to a few harvests by genuine winter dormancy at 37 degrees south. The processing — rolling, resting, roasting — is Taiwanese practice transplanted whole, which makes this a useful test of how much of a tea style travels with the method and how much stays with the place.

The only place in Nigeria where tea grows, and a genuine island of highland climate in a country that otherwise has none. The plateau rises abruptly out of Taraba State in the south-east, continuous with the Cameroonian grassfields across the border, and its combination of altitude, cool nights and reliable rainfall has no equivalent anywhere else within Nigeria's borders. That singularity defines the industry completely: there is nowhere to expand to, the road up is the binding constraint on everything, and processing has to happen on the plateau because leaf cannot survive the journey down.

A broad grassland valley in the Western Highlands of Papua New Guinea, around Banz and Mount Hagen, and effectively the whole of the country’s tea industry. Estates were established here from the 1960s on land already open rather than under forest, at roughly 1,500 metres and only a few degrees south of the equator — so there is no dormancy, no flush structure and no seasonal peak, and plucking runs continuously all year. The crop is made as CTC and sold into blends; the highlands are far better known for coffee grown on the same ground.

The largest island of the Azores, and Europe’s only site of continuous commercial tea production. Plantations were laid out on the north coast in the later nineteenth century as the island’s orange export trade failed, with Chinese specialists engaged to establish processing. The mid-Atlantic climate is mild, humid and frost-free with acidic volcanic soil, and the surviving factories still run rollers and sorters installed generations ago — which is why Azorean tea tastes like a nineteenth-century orthodox black tea, because it is made on the machinery of one.

A narrow strip of the Black Sea coast behind Sochi, at roughly 43–44 degrees north, and the northernmost commercially harvested tea anywhere. The Caucasus range blocks continental cold air from the interior, but winters are still severe enough that only frost-hardy selections survive and the harvest runs for a few months rather than most of the year. Plantings around Solokh-Aul, Dagomys and Matsesta date from the early twentieth century and remain small.

A high-elevation Rwandan estate area near Nyungwe forest, producing some of Africa’s most highly regarded orthodox black tea.

Rwanda’s oldest tea area, in the northern hills near Byumba, and an example of a growing practice unusual in world tea: a substantial part of the planting is on drained valley-bottom marshland rather than on hillside. The marais hold water and organic matter that the eroded slopes above do not, which is precisely why they were reclaimed for the crop, and it gives the district a two-part landscape of hill plots and valley plots with different growth rates. Output is CTC through a factory serving surrounding smallholders and estate land alike.

Tea on the wildest stretch of the South African coast, on the Pondoland plateau above the Msikaba and Mtentu gorges in the Eastern Cape. The siting is unusual and deliberate: this is one of the wettest parts of the country, a narrow coastal belt of grassland and forest cut by deep ravines, with rainfall and acidity that no other South African farming district offers. The estates here were laid out as development projects on communally held land and have carried that character ever since — the questions that decide whether the factory runs are about employment, tenure and management as much as about agronomy.

The largest tea-growing district in South Korea, on the south coast of the peninsula, and the source of most Korean green tea reaching drinkers outside the country.

A South Gyeongsang county on the Seomjin river, and conventionally described as the oldest tea-growing area in Korea — a priority repeated in every Korean account of the drink and recorded here as convention rather than as verified history. Much of its tea still grows from seed on steep wild-ish slopes rather than in planted rows.

A county on the south-western coast of Jeollanam-do, and the one place in Korea where tea agriculture is organised around WILD stands rather than planted rows. Of roughly 93 hectares under tea in the county, about 61 are wild — something over an eighth of all the wild tea in South Korea — growing in the hills at Haengwon-ri, on Gajisan behind the Borimsa temple, and on Cheongwansan above the coast. That inheritance is old enough to be documented: the Sejong Sillok Jiriji records thirteen of the country's nineteen daso, the Goryeo-era tea offices, as having stood in Jangheung. The county's tea is cheongtaejeon, a pounded and pressed coin aged after pressing, and in 2018 the whole system — the wild stands and the manufacture together — was designated Korea's twelfth National Important Agricultural Heritage.

A volcanic island off Korea’s southern coast with a mild maritime climate that allows large-scale flat-land cultivation, in contrast to the mountainous mainland gardens.

A western high-grown district producing the balanced, brisk, golden-liquored style that most blended Ceylon tea is built on, and the reference point against which the island’s other districts are usually described.

The mid-grown district around Sri Lanka’s old royal capital, and conventionally identified as the site of the island’s first commercial tea planting after coffee failed in the 1860s. Its teas sit between the brisk high-grown and the heavy low-grown styles.

The highest of Sri Lanka’s growing districts, giving the lightest and briskest teas on the island — pale in the cup, close to a green tea in delicacy, and the furthest thing from the dark Ceylon of popular imagination.

Sri Lanka’s southern low-grown district, producing the darkest and heaviest tea on the island — thick, malty and deeply coloured, and the elevation band that most people actually picture when they think of Ceylon tea.

Sri Lanka’s other low-grown district alongside Ruhuna, producing dark, heavy, fast-growing tea with long wiry leaf, most of it destined for export blends and the Middle Eastern market.

A Sri Lankan high-grown district between Nuwara Eliya and Uva, producing a tea that shares characteristics of both — bright like Nuwara Eliya, with something of Uva’s aromatic edge.

An eastern high-grown district whose dry-season teas carry a distinctive mentholated, almost eucalyptus-like note that the trade regards as a seasonal signature rather than a constant.

A high mountain area in central Taiwan and the best-known name in high-mountain oolong, where altitude and persistent cloud are credited with the thick, creamy, low-astringency character of the style.

The highest commercial tea gardens in Taiwan, strung along the Central Cross-Island Highway near the Hehuan pass on the boundary of Taichung, Nantou and Hualien. At this altitude there are only one or two harvests a year and the leaf grows very slowly, which is the standard explanation for the tea’s thickness and long finish. Much of the original planting sat on expiring forestry leases and has been progressively cleared, so the name now covers considerably less ground than it once did.

A modest hill in Nantou county, far lower than Taiwan’s famous high-mountain areas, whose roasted style predates them and remains the reference point for what a traditional Taiwanese oolong tastes like.

Taiwan’s southernmost tea, grown at Manzhou near the tip of the Hengchun peninsula in Pingtung, and an outlier in every respect. The gardens sit almost at sea level on soils weathered from raised coral limestone, exposed through the winter to the luoshan feng — the fierce, dry, salt-laden north-easterly that funnels down the peninsula. The bushes grow low and hard with small thick leaves, and the local style answers that: heavily oxidised, firmly rolled, brewed strong, and drunk locally rather than exported. Nobody would site a tea garden here on quality grounds; it exists because people there have made tea for generations.

The north-western county whose Beipu and Emei townships are the traditional home of Oriental Beauty, where the tea jassid population is left undisturbed by design.

One of Taiwan’s highest commercial tea areas, planted among fruit orchards well above two thousand metres. Growth is very slow at this altitude and there are only two harvests a year, which is much of why Li Shan tea is among the island’s most expensive.

The Nantou township that contains Dong Ding, and the place where Taiwan’s competition culture is most consequential. The Lugu farmers’ association contest is among the largest tea competitions anywhere, judged over thousands of entries in a few days, and the rank a lot receives — from the ordinary grades up to the small number of top awards — sets its price for the year and effectively sets the district’s. That has shaped the tea itself: entries are made to a shared house style, medium-oxidised and charcoal-roasted, because that is what the panel rewards, so the competition acts as a standardising force as much as a ranking one.

A township on the Fulu plateau in Taitung, at the southern end of the East Rift Valley, whose tea was promoted under the name Fulu from the 1980s. It sits lower and hotter than the mountain oolong districts, so the local speciality is a heavily oxidised, honey-scented red oolong made from summer leaf — a style that turns the season’s usual disadvantage into the point of the tea.

A low-elevation Nantou township producing a very large volume of mechanically harvested oolong, much of it Si Ji Chun destined for bottled and bubble tea.

A district on the eastern edge of Taipei, now largely built over, and conventionally identified as where baozhong processing entered Taiwan. The account credits a tea maker from Anxi with bringing the method across in the 1880s and teaching it locally, from where it spread into the Wenshan hills; it is standard in Taiwanese tea writing and is recorded here as convention rather than as verified history. A handful of gardens survive on the slopes above the district, which makes Nangang a rare thing: a tea origin swallowed by a capital city and still, marginally, producing.

Taiwan’s largest tea-producing county and the only one entirely inland, containing Dong Ding, Shan Lin Xi and a substantial share of the island’s high-mountain gardens.

The hill district in New Taipei that actually produces most of what is sold as Wenshan Baozhong, and an unusual case of a city’s plumbing shaping a tea style. Pinglin sits in the catchment of the Beishi river, which feeds the Feitsui reservoir supplying Taipei, so the whole township is a protected watershed with agricultural chemical use tightly regulated and construction restricted. Growers work small, steep, hand-plucked plots and make the lightest oolong in Taiwan — barely oxidised, strip-shaped rather than rolled into balls, and closer to a green tea in the cup than to anything from the high mountains.

A township in Hualien’s East Rift Valley, on Taiwan’s sparsely developed Pacific side, known for honey-scented teas made from leaf bitten by tea jassids. Low pesticide use is a precondition rather than a marketing position — the insect has to be allowed to feed for the honey aroma to develop at all — and the warm, humid lowland climate keeps jassid pressure high through the summer.

A district in the hills south of Taipei and effectively the only place in Taiwan where green tea is a serious local tradition rather than a sideline. Sanxia makes a Bi Luo Chun and a Longjing-style green from the Qing Xin Gan Zai cultivar, which is grown almost nowhere else on the island. The district survives on proximity to Taipei and on that cultivar, since it cannot compete on altitude with the oolong mountains.

A high-mountain area in Zhushan township, Nantou, planted among cedar plantations on steep, mist-held slopes. Shan Lin Xi tea is conventionally described as the cleanest and most bracing of Taiwan’s high-mountain oolongs — sharper and greener than Alishan, with a cool, almost minty finish that growers attribute to the deep valley shade and the long daily fog.

The cluster of villages on the ridge below the Alishan forest railway, in Zhuqi township, Chiayi, and the core of what is sold as Alishan oolong. ‘Alishan’ on a packet is a mountain-range name rather than a defined area, and it covers gardens across several Chiayi townships at very different heights; Shizhuo is the band that the trade means when it means the real thing. Morning cloud rolls up the western scarp daily through the growing season, cutting afternoon sun and holding the day-to-night range wide — the conditions the whole high-mountain style is built on.

The hilly district south of Taipei that produces Wenshan Baozhong, the lightest of Taiwan’s oolongs and the one closest in character to green tea.

The basin around Sun Moon Lake in Nantou, and the centre of Taiwanese black tea rather than oolong. Assamica stock was introduced here under Japanese administration in the 1920s, and the area later produced Taiwan’s best-known bred cultivar, Ruby No. 18, whose menthol-and-cinnamon aroma is unlike any mainland black tea. Lake mist and warm, humid summers set the district apart from the high-mountain oolong country immediately around it.

A high plateau in Tanzania’s Southern Highlands, and the country’s principal tea district. At close to 2,000 metres with a single long rainy season, growth is genuinely seasonal rather than continuous — unlike Kenyan production a few degrees north — so Mufindi factories run hard for part of the year and slowly for the rest. Most output is CTC destined for the Mombasa auction.

The highest and coldest part of Tanzania’s Southern Highlands, south of Mufindi, and the region where the country’s smallholder outgrower schemes are concentrated rather than the estate model that dominates further north. Frost occurs on the higher ground in the cool dry season — genuinely unusual for African tea — and, with a single long rainy season, growth stops for months rather than continuing year-round as it does on the equator. Factories here run hard for part of the year and idle for the rest, which shapes the economics more than the cup does.

The forested block mountains inland of Tanga in north-eastern Tanzania, where German colonial administrators established the first tea planting in the territory at the beginning of the twentieth century alongside the Amani research institute. The range’s ancient forest and steep, wet eastern scarp make it one of the most biodiverse areas in Africa, and tea sits within a landscape actively managed for conservation.

The northern Thai highlands where indigenous assamica grows in forest stands, historically managed for miang rather than for a drink: young leaf is steamed and packed to ferment, then chewed as a stimulant and social offering. Modern planting has added conventional green and black manufacture alongside, but the miang forests are the older layer and the reason Thailand counts as a tea origin at all rather than an importer of the practice.

Thailand’s northernmost province and the centre of its oolong industry, which exists because Yunnanese communities who settled the ridges around Doi Mae Salong after the Chinese civil war later imported Taiwanese cultivars and rolling equipment. Jin Xuan and Si Ji Chun grown at 1,000 to 1,500 metres are made in an explicitly Taiwanese idiom, and the tea is best understood as a transplanted tradition rather than an indigenous one.

A Yunnanese mountain village inside Thailand, and the reason Thai oolong exists. The ridge above Mae Fah Luang in Chiang Rai was settled by remnants of a Chinese Nationalist division and their families after they crossed out of Burma, and the community that formed kept its language, its food and its tea. Tea replaced opium here as the cash crop under a substitution programme, using Taiwanese oolong cultivars and Taiwanese rolling equipment, and the result is a district in northern Thailand making a Taiwanese style of tea in Mandarin-speaking villages. The tea is genuinely good and the price gap with Taiwan is mostly about the name on the packet.

The eastern Black Sea province that carries essentially all Turkish tea, on steep slopes between the coast and the Pontic mountains. The mountains hold the moist sea air against the coast, giving very high rainfall and mild frost-free winters on acidic soils where cereals do poorly — the agronomic argument for planting tea here in the first place. Harvest is by hand shear across a few defined cuts per season, so the leaf is coarser than a fine hand pluck and the tea is built for strong, sustained brewing.

The tea belt running along the Albertine Rift from Fort Portal south through Bushenyi and Kanungu, on fertile volcanic and rift-valley soils below the Rwenzori. Rainfall is bimodal and reliable, so plucking continues year-round, and the crop is grown by a mix of large estates and dense smallholder settlement. The industry was largely abandoned during the 1970s and the current planting mostly dates from its rebuilding.

Sheltered valleys on the Fal estuary in south Cornwall, where commercial plucking began in the 2000s on an estate that had grown ornamental camellias since the nineteenth century. The argument for the site is precise: the Gulf Stream keeps winters frost-light, the valleys shelter from salt wind, and the soil is already acidic enough for rhododendron. Yields are tiny, the season is short, and the tea is priced by rarity.

A single garden on Wadmalaw Island in the South Carolina low country, effectively at sea level, descended from plant material assembled during twentieth-century American tea experiments. It is harvested by a purpose-built machine rather than by hand — American labour costs are exactly why the nineteenth-century attempts failed — and produces a mild black tea in modest quantity. Its significance is historical and demonstrative rather than qualitative.

Small artisan plantings on the windward slopes of Hawai‘i Island, mostly around Volcano and the Hāmākua coast, established from the late 1990s on young volcanic soil at 400 to 1,200 metres. Plots are measured in acres, processing is by hand, and growers make green, white, oolong and black tea from the same bushes rather than specialising. The interest is in what a genuinely new terroir does with a plant that has no local tradition behind it.

Vietnam’s northernmost province, on the Yunnan border, holding some of the country’s largest concentrations of old large-leaf tea trees. The leaf is heavily downed — shan tuyet means ‘snow on the mountain’ — and is picked by Hmong and Dao households from trees that are climbed rather than plucked from standing. Material from here supplies most of Vietnam’s speciality output, in green, white and compressed forms.

The southern highland province around Bảo Lộc and Đà Lạt, and Vietnam’s largest tea-planted area. French planters established estates here in the 1920s and 1930s; Taiwanese investors added oolong production from the 1990s, importing Jin Xuan, Cui Yu and Si Ji Chun and the rolling equipment to go with them. The result is a province that makes commodity black tea and Taiwanese-style oolong side by side on the same basalt plateau.

A limestone plateau in Sơn La province in north-western Vietnam, planted as a state farm from the late 1950s and now one of the country’s most organised growing areas. Unlike the ancient-tree districts, Mộc Châu is a modern planted landscape of clonal rows, including Japanese and Taiwanese cultivars introduced for contract green-tea and oolong production. It is where Vietnam’s tea looks least like folk agriculture and most like an industry.

The province north-west of Hanoi where Vietnamese tea science lives. The French established a research station at Phú Hộ in 1918, and it has remained the country’s principal tea institute through every subsequent change of government — the source of the clonal selections planted across the northern midlands and much of the agronomy the industry runs on. The province itself carries a large planted area of that clonal material, worked for commodity green and black tea rather than for the ancient-tree speciality trade further north, and it is the ordinary face of Vietnamese production.

The commune west of Thái Nguyên city that Vietnamese green tea is measured against, and the reason 'Thái Nguyên' means something to a Vietnamese drinker and nothing to anyone else. Tân Cương's hills sit between the Tam Đảo range and the Núi Cốc reservoir, and the tea from them is the domestic benchmark: tightly curled dark-green leaf, a pronounced grassy-sweet aroma the trade calls cốm — young rice — and a bitterness that turns sweet, which is the specific quality Vietnamese buyers judge on. It is one of the few Vietnamese teas sold on its origin rather than as anonymous export material.

The best-known tea province in northern Vietnam and the source of most of the country’s domestic green tea, characterised by a tightly curled leaf and a briskly astringent, sweet-finishing cup.

A northern province whose Suối Giàng commune, high in the Hoàng Liên foothills, is the best-known single stand of ancient Vietnamese tea trees outside Hà Giang. The trees are large-leaf shan stock growing among Hmong villages at around 1,400 metres, and the tea is mostly made as a simple pan-fired green that keeps the material’s thick, honeyed sweetness rather than reworking it into something else.

The southern end of Zimbabwe’s Eastern Highlands, on the Mozambique border, and the country’s main tea district — grown under irrigation, which is what sets Zimbabwean tea apart from every other African origin. Rainfall here is seasonal and, in most years, insufficient on its own, so water is drawn from the Tanganda and Save river systems and applied through the dry months. That makes the crop reliable and the enterprise capital-intensive: this is estate country with large blocks, mechanised handling and its own factories, not a smallholder landscape.

A deep valley on the Mozambique border below the Nyanga massif, in the northern part of Zimbabwe’s Eastern Highlands, and the wetter of the country’s two tea areas. Rain shed off the escarpment and the Mutarazi falls above give the valley a high, reliable rainfall that Chipinge does not have, so the irrigation dependency is lower here. Tea shares the valley with coffee and bananas on estate and outgrower land, and the district’s isolation — a single road descending the escarpment — has shaped its history more than its agronomy has.
