Methyl salicylate
The wintergreen and minty-medicinal note of some Darjeelings and oolongs — a plant stress signal that ends up in the cup.
What a drinker notices
- Aroma — an aroma
- Cooling — a tactile sensation
Wintergreen, mint and a medicinal edge, with a cooling impression in the mouth and nose that is more tactile than gustatory. In a first-flush Darjeeling it reads as lift and character; in a black tea from lowland leaf it reads as odd.
How much of it there is matters: Pleasant in trace, and rapidly medicinal above it. It is one of the narrower windows in tea aroma.
What this gets credited for, wrongly
The 'muscatel' of a second-flush Darjeeling is a different phenomenon from the minty lift of a first flush, and the two get discussed as though they were degrees of one thing. They are not.
What it is
Methyl salicylate is what wintergreen smells like, and the tea plant makes it as part of its response to damage and stress. It appears in teas made from stressed leaf — high-altitude first flush, insect-bitten oolong, some Dan Cong — and it is one of the compounds behind the descriptor tasters reach for when they say a Darjeeling first flush smells minty, medicinal or of embrocation. It is a good example of a note that is prized in one context and considered a fault in another, with no change in the compound itself.
Chemically: Aromatic ester — the wintergreen compound, produced by the leaf under stress.
Where it occurs in the plant
Low in unstressed leaf and raised by cold, drought, insect damage and mechanical injury. Its presence in a finished tea generally reflects growing conditions rather than a processing decision.
What processing does to it
In tea, processing is not a modifier applied to a fixed composition — it is what decides the composition. These are the steps that move this compound, and each links to the step itself.
- Withering — Raises it
- A long cool wither of already-stressed leaf preserves and concentrates it, which suits first-flush Darjeeling manufacture.
- Oxidation — Leaves it broadly alone
- Comparatively stable through the light oxidation a first flush receives, which is part of why the note survives into the finished tea.
How brewing brings it out
Extraction rate: Fast — among the first things out of the leaf
Volatile and out quickly. Most obvious in the aroma of the dry leaf and the first pour, and gone by the time the cup has cooled.
Across infusions: Front-loaded and fading fast; by the third infusion the minty top note has largely gone while the body of the tea has not.
Water: Volatile and lost to standing rather than to water chemistry — the wintergreen note of a fresh Darjeeling is a first-cup phenomenon.
What you can change
- Smell the warmed dry leaf, where it is most concentrated
- Drink the first infusion promptly
Teas this compound defines
Read next
- Nerolidol — A woody-floral aroma compound that rises when the leaf is stressed — by bruising, and famously by insects.
- Linalool — A major floral aroma compound of tea, largely stored bound to sugar in the leaf and set free by processing.
- Jasmine lactone — A creamy, peach-and-jasmine note that arrives in tea both from scenting with real flowers and from the leaf's own chemistry.
What this page does not say
Methyl salicylate has uses outside tea that this record does not describe or compare. It says nothing about what it does in a body at any amount.
