【冷や酒 (ひやざけ hiyazake)】cold sake
冷や酒 (hiyazake) is technically sake served at room temperature, but it is commonly called “cold sake” since back when there were no refrigerators, sake was served either warm or 冷や (hiya) — “cold” at room temperature. Both 冷や酒 (hiyazake) and 冷酒 (reishu) may be considered “cold sake,” but there is a difference.
