Made from only rice, rice koji, salt, and water; Junmai (pure rice) soy sauce (gluten free!) is the perfect soy sauce alternative for those who are allergic to gluten or soy. Taisho-ya Shoyu, an esteemed soy sauce and miso specialty maker in Shimane prefecture, over the span of 10 years and with enormous effort, developed this truly innovative sauce. In order to replicate soy sauce’s rich umami, slight sweetness, and intense aroma, they blend sake-kasu (sake lees) and shiro-nuka (premium rice bran) sourced from a local sake brewery, and add rice koji to promote fermentation. After aging in cedar barrels, the sauce develops a clean flavor and aroma along with a pleasing dark color.
