Definition:
Tencha (碾茶) is the pre-ground intermediate form of matcha — shade-grown tea leaves that have been steamed and dried flat, with stems and veins removed, but not yet stone-ground into powder. It is occasionally brewed as a whole-leaf tea, producing a flavour profile similar to gyokuro but with even softer character from the flat, unrolled leaf structure.
In-Depth Explanation
The agricultural stage of tencha production is identical to gyokuro — both use 20–30 days of intensive shade-growing. The divergence occurs at processing. While gyokuro leaves are rolled into needle shapes (which concentrates cell contents and develops the characteristic needle appearance), tencha leaves are dried flat with no rolling. Stems and veins are then removed mechanically in a process called aracha refining, and the remaining flat, de-veined leaf fragments are what becomes tencha.
When stone-ground, tencha yields what we call matcha. The quality of matcha depends directly on the quality of the tencha source. Premium ceremonial-grade matcha is made from tencha selected for brightness, aroma, and fine particle responsiveness in grinding.
As a standalone tea: Brewed tencha dissolved in hot water (without grinding) produces an extremely delicate, sweet cup — the same shade-grown L-theanine profile as gyokuro, but different in texture because the leaf isn’t rolled. This is rarely commercially marketed but appreciated by tea specialists.
History
Tencha is the oldest form of Japanese shade-grown tea — the shade-growing technique was originally developed for tencha production in Uji in the 13th–14th century, before it was adapted to produce gyokuro for whole-leaf brewing. Matcha’s place in the chanoyu ceremony required a reliable supply of high-quality tencha, making Uji’s tencha production central to Japanese tea culture from the medieval period onward.
Common Misconceptions
“Tencha is just raw matcha” — Tencha requires specific agricultural conditions (shading) and specific processing (flat drying, de-stemming). It’s not simply any tea leaf before grinding.
“Tencha can be brewed like any green tea” — The fragile, flat leaf structure means brewing parameters differ from rolled green teas. It dissolves partially rather than steeping cleanly.
Taste Profile & How to Identify
Aroma: Sweet, marine, shade-tea character — similar to gyokuro.
Flavour: Very soft, sweet, umami; lower clarity than gyokuro due to the flat, unrolled leaf structure dissolving slightly into the brew.
Colour: Pale to medium green.
Brewing Guide
As a standalone brewed tea (not typical — for matcha, follow matcha preparation):
| Parameter | Value |
|---|---|
| Amount | 3–4g per 100ml |
| Temperature | 50–60°C |
| Method | Infuse briefly; some leaf material will dissolve |
Social Media Sentiment
Tencha as a standalone brew is extremely niche — barely discussed even in specialist tea communities. Most references to tencha on r/tea are in the context of matcha sourcing discussions and quality assessment. It occasionally surfaces in conversations about how to taste the “raw material” of matcha.
