Inside the Bowl: A Koicha Tasting

Koicha (濃茶, "thick tea") is what the Japanese tea ceremony was actually built around. Twice the matcha, half the water. Kneaded slowly with the bamboo whisk, not foamed. The result is closer to liquid jade than to tea: glossy, viscous, paint-thick, no foam at all.

Three things most people don't know about it: it is the older form. Koicha came first. Usucha is the lighter daily version that came later. In a full tea ceremony koicha is the formal centrepiece, usucha the relaxed close.

Not every matcha can be koicha. The concentration that makes a great usucha turns most matchas bitter and grippy. Koicha-grade tea is shaded longer, picked younger, and milled finer. The leaf is built for it. Koicha exposes a tea's umami, depth (kokumi 「コク」), mouthfeel, and finish length in a way usucha softens and hides.

This is a tasting, not a tea ceremony. No bowing, no kneeling, no choreography. You will taste 4 full-strength koicha pours. Two from Marukyu Koyamaen (Uji, Kyoto), the classical Japanese benchmark with over 300 years of tea-making. Two from MICHI Tea (Amsterdam), Europe's speciality matcha brand, sourcing direct from Kyoto-prefecture farmers. Same Uji terroir, two philosophies: the classical blender's craft, then the contemporary single-cultivar lens.

You walk out knowing what koicha is, how to prepare it, how to taste it, what kokumi feels like in the bowl, and a better instinct for which matcha you reach for when you want depth rather than brightness.
