Thailand
Two tea traditions running in parallel. The northern forests hold indigenous large-leaf trees whose leaf is fermented into miang, chewed rather than infused, in a practice that predates any planted estate; the mountains of Chiang Rai, meanwhile, carry Chinese and Taiwanese oolong cultivars planted from the later twentieth century by Yunnanese communities who settled there. Alongside both sits a large commodity sector feeding Thailand’s sweetened iced-tea market.
History on this page: TeaHQ synthesis
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
This country’s description dates the establishment or the collapse of an industry. The label says on what basis — it governs the historical statements, not the production figures below, which carry their own definitions and sources.
Production, trade and price
| Measure | Year | Value | Basis | Published by |
|---|---|---|---|---|
| Harvested area | 2023 | 21,243 ha | FAOSTAT QCL element 'Area harvested' for item 667 / CPC 01620 'Tea leaves', in hectares. FAO's methodology note warns that for permanent crops such as tea 'data may refer to total planted area' rather than area actually harvested, so this is the area under tea and not necessarily the area picked in the year. The associated crop is measured as green leaf. FAOSTAT flags this cell A, an official figure reported by the country. | Food and Agriculture Organization of the United Nations (FAO), Statistics Division |
| Production | 2023 | 106,347 t | FAOSTAT QCL element 'Production' for item 667 / CPC 01620 'Tea leaves', in tonnes. FAO's QCL methodology note states the domain 'contains production data for primary products', so this counts GREEN LEAF as plucked, not made tea. It is roughly four to five times the made-tea figure the same country's tea board publishes. FAOSTAT flags this cell A, an official figure reported by the country. | Food and Agriculture Organization of the United Nations (FAO), Statistics Division |
| Yield | 2023 | 5,006 kg/ha | FAOSTAT QCL element 'Yield' for item 667 / CPC 01620 'Tea leaves', in kilograms per hectare, computed by FAO from the production and area figures rather than reported directly. Because production is GREEN LEAF and the area may be planted rather than harvested, this is green-leaf yield per hectare planted and is not comparable with a made-tea yield. FAO states that yields of permanent crops 'are not as reliable as those for temporary crops'. FAOSTAT flags this cell A, an official figure reported by the country. | Food and Agriculture Organization of the United Nations (FAO), Statistics Division |
Figures are reproduced as their publisher stated them and are not converted, averaged or ranked. Where two publishers disagree, both rows appear — this comes from Food and Agriculture Organization of the United Nations (FAO), Statistics Division. The largest single trap in tea statistics is that FAO’s series counts green leaf as plucked while national tea boards count finished made tea, and the two differ by roughly a factor of four and a half. The basis column says which each row is, and a figure without it is not comparable to one with it.
How production is organised
Small family holdings on the northern mountains, many of them descended from settlement and crop-substitution programmes, selling to nearby processing sheds — alongside a large, quite separate commodity sector supplying the domestic iced-tea market. The oolong side is organised on a Taiwanese model of small grower plus small roaster rather than on a plantation one.
How firm this is: Inferred by TeaHQ from general knowledge of the trade rather than taken from a source that states it.
What it produces
Rolled and roasted oolong from introduced Taiwanese cultivars in the northern mountains, indigenous assamica used for miang and for black tea, and bulk leaf for the domestic iced-tea trade.
How firm this is: Inferred by TeaHQ from general knowledge of the trade rather than taken from a source that states it. The three strands are well attested; their relative scale was not verified against a primary source.
What it is known for
The categories this country is most associated with. Being known for a category is a fact about reputation and volume rather than about quality.
- Oolong — Partially oxidised teas, bruised deliberately and often roasted — the widest-ranging category in tea.
Growing regions in Thailand
Named districts with their own elevation, climate and character. Elevation figures are recorded as ranges because sources disagree on where a district begins and ends.
How tea is drunk here
Thai iced tea, deep orange and heavily sweetened, is made from a flavoured and coloured blend rather than from the country’s mountain oolong. The two have almost nothing in common beyond the leaf.

Written comparisons
Where TeaHQ has set this producing country against something it is routinely confused with, and argued the differences out in full.
- Thailand vs Myanmar as tea origins — Two countries in the same upland belt with the same indigenous large-leaf stock, and two different relationships with it. Both have long traditions of eating fermented tea; only one of them has also built a modern export industry on imported cultivars.
