Awabancha is one of the post-fermented teas of Shikoku Island in Japan.
This tea is fermented once, while Ishizuchi Kurocha and Goishicha are fermented twice.
The lactic acid bacteria produce a sour, slightly sweet flavor.  This lactic acid bacteria has been introduced by several researchers as having blood sugar suppression, intestinal regulation, and anti-allergic effects.
Awabancha was registered Ark of Taste by Slow Food in 2020.
