Toasted grain
Toast, rice, popcorn and warm bread — Maillard chemistry, and the clearest case in this vocabulary of a note with a known cause.
Toasted grain notes come from the Maillard reaction: amino acids and reducing sugars in the leaf reacting under heat to produce a large family of new aroma compounds, pyrazines prominent among them, which is the same chemistry that browns bread crust and roasted coffee. This is one of the few places in tea sensory description where the mechanism is genuinely established rather than inferred, and it is worth saying plainly for that reason. It appears wherever leaf meets sustained dry heat — pan-fired Chinese greens, hojicha, the final firing of Japanese tea, roasted oolong, and the traditional two-stage drying of Huangshan and Anhui greens. Genmaicha is a special case: its toasted rice note comes from actual roasted rice blended with the tea, not from the leaf. Eighteen teas here carry the plain string 'toasted grain', making it one of the largest single clusters in the catalogue.
Which sense this is
Aroma. Volatile compounds, smelled through the nose or retronasally while drinking. Nearly all descriptive tea vocabulary is here, including words people say they can taste.
Compound descriptor. A familiar thing used as shorthand for a mixture of sensations. Nobody detects 'chestnut' — they recognise it.
Where it comes from
- Established chemistry
The Maillard reaction between amino acids and reducing sugars under heat produces the pyrazines and related compounds behind toasted and roasted aromas. This is a well-established route and the same one that browns bread and coffee.
The chemical route is identified in the literature. Often a family of related compounds rather than one named molecule.
- Processing step
Pan-firing, final firing, re-firing and the two-stage drying used for Anhui greens all apply the sustained dry heat this requires.
A named production step reliably produces it. A statement about practice, not about chemistry.
Processing: process-pan-firing, processing-s32-hiire, process-re-firing, processing-staged-drying. Types: type-green-tea.
Not to be confused with
- Fresh grass (Aroma) — Cut-grass green — the smell of the fresh leaf surviving into the cup, and the marker of a green tea that is actually fresh.
The phrases this covers
Editors write tasting notes in their own words. These are the exact phrases in the catalogue that this descriptor accounts for — the mapping is authored phrase by phrase, so nothing is grouped by a rule that guessed.

A tasting note is a comparison, not a measurement. Where the route from leaf to sensation is established it is labelled as such above; where it is not, the page says so rather than supplying a mechanism the descriptor has not earned. See the rest of the vocabulary for how the axes divide up.
