The word Junmai literally means "Pure Rice" so it refers to pure rice (non-additive) sake. Additionally, the Junmai classification means that the rice used has been polished to at least 70 percent. While it’s hard to over-generalize, Junmai sake tends to have a rich full body with an intense, slightly acidic flavor. This type of sake can be particularly nice when served warm or at room temperature.
