Sencha is Japan's everyday green tea, accounting for 60-70% of Japanese tea production. The defining feature is steam fixing, a quick steam treatment instead of pan firing, which produces vivid green colour, vegetal umami flavour, and the distinctive needle shaped rolled leaves.

The history

Sencha as we know it dates to 1738, when tea master Nagatani Sōen developed the modern Japanese steaming technique in Uji (Kyoto). Before this, Japanese green tea was processed differently. Sōen's method, quick steaming followed by rolling, became standard and is still used today.

Sencha replaced earlier Japanese tea forms (matcha precursor tencha) as the everyday drinking tea. Matcha continued for ceremonial use; sencha for everyday.
