Reading the bitterness
Tencha consists of new shoots grown under cover, steamed, dried without rolling, and finished by removing stems and veins; it is the raw material for matcha. According to the official Urasenke website, plucked shoots are evenly steamed and dried without rolling to make rough tea, then stems and veins are removed to leave only tender leaves, called 「仕上碾茶」 (in translation: "finished tencha"). The Japan Tea Central Association defines matcha as 「碾茶を茶臼等で微粉末状に製造したもの」 (in translation: "tencha ground into a fine powder with a tea mill or similar device"). Thus the connection between ground tencha and matcha is supported both by the industry association's definition and Urasenke's process description.
Tencha leaves are produced by shade cultivation that blocks direct sunlight. The absence of direct sunlight is described by Urasenke as reducing astringent constituents and that only the new shoots are picked in the shaded garden. A Shizuoka Prefecture field trial (2016) compared first-flush 'Yabukita' under several shading conditions, from no cover to 85–98% cover for 5–20 days, supporting that tencha and matcha production is planned around shade treatment.
