A practical glossary of core Japanese matcha terms so beginners can decode product pages, labels, and tasting notes without guesswork.
Japanese Matcha Terminology: 25 Terms Explained for UK Buyers
If matcha product pages feel full of unfamiliar words, this guide is your quick decoder.
If you are brand new, read what is matcha first, then come back to these terms.
Fast-start terms most shoppers see first
Matcha (抹茶)
Finely stone-milled green tea powder made from shade-grown tea leaves.
Tencha (碾茶)
The leaf material used to make matcha before milling. Better sourcing pages often mention tencha origin.
Ceremonial grade
A market term for powders positioned for straight drinking. It is not a legally standardised grade, so compare colour, freshness, and flavour notes too.
Culinary grade
Matcha intended for lattes, baking, and cooking. Usually stronger and more robust, often better value for recipes.
First harvest / Ichibancha (一番茶)
First seasonal pick, often with sweeter and softer flavour profiles.
Taste and texture terms in reviews
Umami (旨味)
Savoury depth that gives premium matcha a rounded, brothy sweetness rather than sharp bitterness.
Astringency / Shibumi (渋み)
Drying sensation on the tongue. Some is normal; excessive astringency can indicate poor prep, old powder, or lower quality.
Bitterness / Nigami (苦味)
A direct bitter taste. Overheating water and over-dosing powder are common causes.
Aroma / Kaori (香り)
The fragrance profile (fresh grass, seaweed, sweet vegetal notes). Dull aroma often signals age or oxidation.
Mouthfeel
How creamy, thin, chalky, or silky the drink feels. Whisking technique and sifting matter here as much as powder quality.

Production and quality terms
Shade-grown / Ooishita saibai (被覆栽培)
Tea plants are shaded before harvest, increasing chlorophyll and amino acid development.
Stone-milled / Ishi-usu (石臼)
Traditional milling method producing very fine particles and smoother texture.
Cultivar
The tea plant variety (for example, Yabukita or Okumidori). Different cultivars can change sweetness, aroma, and finish.
Blend (Gou-gumi)
Many brands blend cultivars or regions for consistency across batches.
Single origin
Matcha from one region or producer rather than a broader blend.
Preparation terms you may see
Usucha (薄茶)
"Thin tea" style, typically lighter concentration and the most beginner-friendly way to drink matcha.
Koicha (濃茶)
"Thick tea" style using more powder and less water; usually reserved for high-grade matcha and advanced preparation.
Chasen (茶筅)
Bamboo whisk used to mix and aerate matcha.
Chashaku (茶杓)
Bamboo scoop used to portion powder.
Chawan (茶碗)
Tea bowl designed for whisking and drinking.
Buying and storage terms
Nitrogen-flushed
Packaging method that reduces oxygen exposure to help preserve freshness.
Best-before date
Useful freshness marker. Smaller packs are often smarter for home use if you drink matcha occasionally.
Jade green colour
A visual shorthand for fresher, well-shaded matcha; still verify with aroma and taste.
Oxidation
Air, heat, light, and moisture degrade flavour and colour over time.
Price per gram
The simplest way to compare value between tins and pouches.
