Description
Yamabuki Nadeshiko is a new type of tea made by controlled microbial fermentation that produces (in Yunomi's opinion) a slightly sour tea liquor with a subtle strawberry flavor.
Kurokoji Fermentation
Kawamura Denbei, known as the "Father of Shizuoka Yeast" and president of microbial research and development company Riversion, developed this tea based on his years of research into koji molds (aspergillus oryzae) used for making Japanese sake, soy sauce, and miso among other foods. The specific type of koji used is black koji or kurokoji 黒麹, and is most famous for making the bold flavors of awamori sake in Okinawa. Joint research with Shizuoka and Saga Universities revealed that tea processed with kurokoji creates two polyphenols, named Teadenol A and Teadenol B.
At Osada Tea's clean room facility, a patented kurokoji fermentation starter is mixed into leaves grown organically from the farmers of the Isagawa Tea Coop in Haruno Village (in the mountains of the famed Tenryu district of western Shizuoka). This differs from traditional Pu-erh tea which is naturally fermented (allowing the natural molds in the air to start fermentation in the leaves).
