Two productions, described precisely
Scenting exploits the absorbency of dry leaf. Finished tea is placed in contact with an aromatic material — jasmine blossoms, osmanthus, chrysanthemum, rose, pomelo flower, or smoke from burning pine — for a period, so that the volatile compounds released by that material migrate into the leaf. The aromatic material is then usually removed and the tea is refired. Nothing has been added in the sense of a substance remaining in the packet; what remains is tea that has taken on an aroma. Flavouring adds a preparation to the finished leaf, most often a liquid flavouring sprayed or tumbled onto it, sometimes with dried fruit, petals or peel included as well. Both are legitimate, both produce teas people enjoy, and they are different enough in the cup that a buyer benefits from knowing which they have. A third production sits between them and confuses the vocabulary further: teas blended with dried botanical material that remains in the packet and contributes in the pot — rose petals, osmanthus flowers, dried peel, spices. Nothing has been absorbed and no flavouring compound has been added; another ingredient is simply present. Keeping this apart from both scenting and flavouring is worth the effort, because it is the case where the ingredient list is most obviously informative and where the material is visible in the cup.
How the ingredient list settles it
This is the rare case where a regulated field answers the question outright. A scented tea’s ingredient list names the tea and, if the botanical material was left in, the botanical: green tea, jasmine flowers. A flavoured tea’s list names a flavouring: black tea, natural flavouring, or black tea, bergamot flavouring. Where both appear, the tea has been scented and flavoured, which is very common in commercial jasmine and Earl Grey production and is not visible from the front of the pack. The absence of any flavouring entry on a tea with a strong aroma is therefore a positive claim about how the aroma got there. This is also why the ingredient list is the most reliable text on a tea packet: the marketing copy above it can call anything jasmine tea, and the list has to say what is in it. There is one limitation to the method. An ingredient list tells you that a flavouring is present and generally not how much, and the sensory contribution of a small addition to a strongly scented base can be modest. So the list answers the categorical question cleanly and the question of proportion only partially. For that, the behaviour across infusions described in the next section is the better test, and it is one a drinker can run at home in ten minutes.
The difference in the cup
Scented aroma is held in the leaf and comes out with the tea, so it arrives with the liquor, persists into the second and third infusions, and fades roughly in step with the tea itself. A good jasmine green tea smells of jasmine in the wet leaf and in the cup, and the aroma reads as part of the tea rather than sitting above it. Flavouring applied to the surface behaves differently: it is strongly evident in the dry leaf, front-loads heavily into the first infusion, and is largely gone by the second, which is why flavoured teas so often smell more impressive in the packet than they taste in the cup and why they rarely reward re-steeping. Neither behaviour is a fault. But it means a flavoured tea is a one-infusion product by construction, and a scented tea is not. The dry leaf is the other diagnostic. A surface-applied flavouring is at its most volatile before any water has touched it, so a flavoured tea typically smells dramatic in the packet and comparatively modest in the cup, while a well-scented tea smells restrained dry and opens up markedly in the wet leaf and the liquor. That inversion is one of the more reliable ways to tell the two apart when the packaging is unhelpful, and it takes one sniff before and one after.
How good scenting is done, and what it costs
Jasmine tea is the reference case. Green tea is layered with jasmine blossoms picked that day and allowed to open at night, held together for hours, then separated; the better grades repeat the process over several successive nights with fresh flowers each time, which is what a seller means by a number of scentings. Each round costs flowers, labour, handling and a refiring that risks the tea, which is why scenting count tracks price closely. Because the flowers are removed at the end, visible blossoms in a finished jasmine tea are usually decorative and can indicate scenting that needed help — with the deliberate exception of certain Sichuan styles where the flower is left in as part of the product. Osmanthus, chrysanthemum and rose scenting follow similar logic with different materials and different holding times. The seasonality is worth understanding as well. Jasmine scenting depends on flowers picked at the right stage on the day they are used, which ties production to a short summer window even though the base green tea was made in spring. A jasmine tea is therefore dated by two events rather than one, and a seller who states both the base tea’s harvest and the scenting season is describing the product more completely than one who states neither.
Why flavoured tea is not the poor relation
Flavouring is what makes a large part of the tea market work, and doing it well is a skill. It allows a consistent product year after year from a base tea that varies; it produces the Earl Greys, chai blends and fruit teas that a great many people drink daily and enjoy; and it makes tea approachable for drinkers who do not want to learn a category first. The honest criticisms are narrower. Flavouring can hide a weak base tea, which is a real practice and is why a flavoured tea rarely tells you anything about the leaf underneath. It front-loads, so it is poor value if you re-steep. And it dominates storage, since the flavour compounds are volatile and will scent anything stored with them. Buying it knowingly is the whole recommendation here. There is a further consideration for households, which is that flavoured teas are the ones most likely to be shared with people who do not drink tea attentively, and they do that job well. The reasonable position is the one this catalogue takes throughout: know what you are buying, match it to the use, and do not pay a leaf price for a product whose character comes from elsewhere. A well-made flavoured tea at a fair price is an entirely sensible purchase.
Smoked tea, and the edge cases
Smoking is scenting by another aromatic source: traditional Lapsang Souchong from Tongmu is dried over pine smoke, and the smoke enters the leaf exactly as jasmine aroma does. A great deal of tea sold as Lapsang is instead made elsewhere with heavier smoking or with smoke flavouring added, which is a different product and is usually identifiable from the ingredient list and the price. Genmaicha is a third case again — roasted rice blended with the tea, an added ingredient that is neither a scenting nor a flavouring but a physical component present in the cup. Blends with visible botanical material, such as chai with whole spices, are the same. The three-way distinction worth keeping is whether an aroma was absorbed, added as a compound, or contributed by another ingredient that is still there. Earl Grey is the most instructive edge case of all, because it spans the entire range. Versions exist made with natural bergamot oil, with a nature-derived flavouring preparation, and with synthetic material, at every price point, and the ingredient list distinguishes them only partially. Since bergamot is an oil applied to the leaf rather than an aroma absorbed from a living flower, Earl Grey is a flavoured tea in every version, and the differences between them are differences of flavouring quality rather than of production category.
