Fresh matcha can smell grassy, vegetal, sweet, creamy or lightly marine. The exact aroma depends on origin, cultivar, harvest, processing and freshness.
Common positive aromas
- Fresh-cut grass or tender greens
- Sweet peas or spinach
- Cream, nuts or soft vanilla-like sweetness
- Sea breeze or nori-like marine notes
A marine aroma is not automatically “fishy.” A clean seaweed-like note can accompany umami; a stale, sour or strongly fishy odor may indicate age, contamination by odors or poor storage.
Dry versus prepared aroma
Smell the dry powder first, then prepare it with consistent water. Warm water releases additional aromas and makes comparison easier.
Warning signs
Cardboard, dust, mustiness, sourness or a flat aroma can indicate oxidation, moisture exposure or absorbed odors. Matcha readily picks up surrounding smells.
For café tasting
Use identical cups, weights and temperatures. Record the dry aroma, wet aroma and finish separately, then repeat the test with the café’s milk.
