Usucha 薄茶
The everyday, more forgiving style — lighter, frothy, and the best place to start.
Full usucha guide →Koicha (濃茶, "thick tea") is matcha at its most concentrated — kneaded, not whisked, into a glossy, paste-like tea. It demands high-grade leaf and a gentler hand than usucha.
Koicha uses roughly double the matcha and about half the water of usucha, producing a dense, viscous tea closer to a thick syrup than a beverage in the everyday sense. It's traditionally reserved for the most formal tea gatherings and made with the finest, oldest-vine ceremonial matcha available — the concentration leaves nowhere for a mediocre leaf to hide.
The technique is different, too: koicha is kneaded with slow, folding strokes rather than whisked, so it never develops foam. Done well, the surface should look glossy and pour slowly, like warm honey.
Yes — use the highest grade you can get. Koicha uses roughly double the powder of usucha in about half the water, so any bitterness or astringency in the leaf is magnified rather than diluted. Culinary-grade matcha almost always tastes unpleasant at koicha strength.
Koicha is dense, concentrated, and meant to be sipped slowly rather than drunk like a cup of tea. A small serving — often just a few spoonfuls — lets the sweetness and umami of high-grade matcha come through without becoming overwhelming or overly filling.
It's a compromise. Koicha is traditionally kneaded, not whisked, so a spinning frother tends to introduce air and small bubbles that don't belong in a paste-like tea. If a chasen isn't available, pulse briefly and fold with a spoon between pulses rather than running the frother continuously.
