이소지만 오이가와노 메구미 카와루토키

Isojiman Ooigawanomegumi Kawarutoki celebrates the gifts of the Oi River (Ooigawa), the water source that defines Isojiman Shuzo's sake in Shizuoka. The name, meaning roughly blessing of the Oi River, a time of change, suggests a seasonal or transitional character tied to a particular time of year. As a junmai expression, it focuses on pure rice flavor supported by the soft, pristine river water that is central to Isojiman's identity.
