Uji matcha is the global benchmark for stone-ground powdered green tea. Production traces to monk Eisai bringing seeds and Song- dynasty powdered-tea practice to Uji around 1191. The shading technique that defines modern matcha emerged among Uji growers in the 16th century. Processing per Wikipedia: leaves are shaded 2–3 weeks (yoshizu screens or komo straw mats), steam-fixed, dried without rolling (this gives tencha, the matcha base), then destemmed and deveined and stone-ground into the powder. Koicha (濃茶, "thick tea") requires the highest grade matcha — young first-flush leaf from old bushes; usucha (薄茶, "thin tea") is the everyday whisked grade.

Per Wikipedia — koicha (thick tea) requires the highest grade matcha, typically prepared as ~4 g powder whisked with ~30–50 ml water at ~75 °C until a paint-like paste forms. Usucha (thin tea) uses ~2 g per 70-80 ml of water and is whisked into a froth. Use a chasen (bamboo whisk) and chawan (bowl) — there are no infusions.
