it is authentic sweet potato characterized by the mellowness of aroma taste, while having the characteristic scent of black koji. I used golden senpusu as a raw material, carefully cut both of those glue, and suppressed ingredients of offensive odds as much as possible. Koji uses black koji. Also, even if you stick to raw materials and distillation, if the filtration is too strong, your sweetness and depth will fly away, and you can do something with no spicy taste. In order to prevent it, we filter by the method called "roughing filtration", so as not to destroy the taste. ORIGIN:SAGA ,ALCOHOL:25%,BASE:SWEET POTATO
