Unveiling Coffee Astringency: Distinguishing Astringency from Tea-Like Notes! What Do Tea-Like Notes Mean in Pour-Over Coffee?

Whenever customers hesitate in front of the FrontStreet Coffee bean menu, FrontStreet Coffee recommends suitable beans by asking about their preferences — a quick way to break the choice paralysis. Over time, FrontStreet Coffee noticed that beyond the popular requests for florals, fruit acidity, and nutty-chocolate notes, plenty of people also ask for something more niche: "I'd like a coffee with a strong tea-like character."

That might surprise some — tea is tea and coffee is coffee, so how can a coffee taste like tea?

In fact, it genuinely can. The latest version of the coffee flavor wheel includes "black tea" as a descriptor, even if it sits within the floral category.

And the wheel only lists black tea. In practice, the tea-like nuances you can find in coffee go far beyond it — if you read FrontStreet Coffee's tasting notes regularly, you'll see green tea, oolong, and white tea appear in aftertaste descriptions too. Which raises the question: why do coffees carry tea-like notes at all?

Why Coffee Has Tea-Like Nuances

The answer is simple: coffee contains some of the very same aromatic compounds found in tea leaves. As FrontStreet Coffee explained in "Is Coffee Flavor Just Mysticism?", the flavors we perceive come from the combination of volatile compounds and taste. Once coffee enters the mouth, taste buds register the intensity of the flavor, then volatile aromatics ride up into the nasal cavity as we swallow, where olfactory receptors capture them. The brain then merges the tastes and aromas and searches memory for matching foods — that merged perception is what we call flavor.

The same mechanism explains tea-like notes: because coffee shares certain aromatic compounds with tea, our brains naturally make the association. That said, FrontStreet Coffee more often uses "tea-like character" rather than the more literal translation "tea rhyme," because in most cases the impression needs the drink's texture and mouthfeel to make the "tea" fully three-dimensional.

The Phenomenon of "Salivation and Sweet Aftertaste"

Salivation followed by a sweet return is a sensation familiar to any tea drinker: a slight astringency on the tongue, then sweetness welling up after. The mechanism traces back to tea polyphenols — one of the main contributors to tea's color and aroma. Among the polyphenols, tea tannins make up the largest share; they deepen the tea's intensity, roughen its texture (the astringent feeling), stimulate the salivary glands, and thereby generate the sweet aftertaste. The higher the tannin concentration, the stronger and longer-lasting the effect.

Organic acids can produce the same effect: they also stimulate salivary secretion, much like biting into a bayberry or green plum. Since coffee is naturally rich in organic acids, we frequently get that salivation-plus-sweet-return sensation when drinking it. Combined with the tea aromas contributed by other compounds, it produces the full "tea-like character" — the taste of tea and the textural experience of tea together.

One caveat: because astringency in coffee mainly comes from chlorogenic acid, coffee astringency differs slightly from tea astringency — it can carry a faint bitterness tied to the bean's sugar content. And like any flavor descriptor, not every coffee will show a tea-like character.

What Types of Coffee Have Tea-Like Character?

Whether a cup shows tea-like character depends closely on variety, cultivation, processing, roasting, and brewing. The first three determine whether tea-like character exists and which type; the last two determine its intensity. Just as the Geisha (T2722) variety leans floral thanks to the extra terpenes written into its genes, some beans carry tea-like compounds from the start — Geisha (T2722) being, again, an example...

Cultivation goes without saying: the growing environment shapes how much of these compounds accumulate. Some origins are famous for it, such as Ethiopia's Sidamo and Yirgacheffe. Processing then decides the type of tea impression — washed coffees are cleaner, so their tea-like character leans fresh and pure, like green tea (not always), while naturals ferment more, pushing the impression toward richer styles, like honey-scented black tea (again, not always)...

Roasting determines aroma expression. Coffees that show tea-like character are almost always roasted medium or lighter — medium, medium-light, or light. With less caramelization, the cup carries no burnt bitterness to mask its innate aromatics, so the tea-like notes stand out. It's why you so often hear "this doesn't taste like coffee — it tastes like tea": the roast isn't dark enough to deliver the "coffee flavor" (bitterness) of traditional expectations, and the fruit-and-floral character plus tea impression makes the cup feel more like a floral fruit tea.

Finally, brewing. Because astringency and tea-like character surface mainly in the aftertaste and the sweet return, the extraction must be reasonably complete. Under-extracted coffee — or coffee extracted at too low a yield — will show weak aftertaste and sweet return, and the tea-like character along with it.

So if you want tea-like character in your cup, buy beans known for it and make sure you extract them fully. For specific recommendations, start with these: Panama Mariposa, Boquete Geisha, La Esperanza Geisha, Peru Geisha, Yirgacheffe Gudina, Sidamo Fakuq, Alo, and Elto.
