純米酒 (Junmai sake) is a type of Japanese rice wine made exclusively from rice, water, yeast, and koji mold. It does not contain any added alcohol or sugars, which distinguishes it from other sake varieties. The rice used in Junmai sake is polished to remove the outer layers, affecting its flavor and aroma. This sake is known for its rich, full-bodied taste and often has a slightly acidic profile. It can be enjoyed warm or chilled, making it versatile for various occasions. Many people appreciate Junmai sake for its authentic representation of traditional Japanese brewing methods.
