Koicha 濃茶
The ceremonial extreme — roughly double the powder, half the water, kneaded rather than whisked.
Full koicha guide →Usucha (薄茶, "thin tea") is the light, frothy bowl most people mean when they say "a bowl of matcha." Here's the ratio, temperature, and whisking technique that make it consistently good.
Usucha is matcha whisked with a relatively generous amount of water, producing a light-bodied tea topped with a fine, even layer of foam. It's the default way matcha is served — at home, in cafés, and to individual guests in most casual tea gatherings. Where koicha is thick and paste-like, usucha should pour easily and taste bright rather than heavy.
Because the ratio sits on the diluted end of the spectrum, usucha is a good starting point for anyone new to whisking matcha: small ratio mistakes are less punishing here than they are in koicha, but you'll still notice a bowl that's too strong, too weak, too hot, or under-whisked.
Usucha is the informal, everyday style of whisked matcha, and it's also the preparation most commonly served to individual guests in casual tea gatherings. Koicha, the thick style, is reserved for more formal occasions and higher-grade leaf. If you've had matcha at a café or made it at home, it was almost certainly usucha.
You can, but it's less forgiving than a latte or iced matcha. Culinary-grade matcha is more astringent and bitter, and usucha has nothing — no milk, no ice — to soften that. If your usucha turns out harsh, try a lower strength setting, slightly cooler water, and a fresher tin.
Grassiness usually means the matcha is stale or lower-grade; bitterness usually means the water was too hot or the ratio too strong. Start at 75°C with the standard ratio, sift every time, and taste before you add more powder — it's easy to correct a mild cup by whisking in a touch more matcha, harder to fix an over-strong one.
