In 1991, Sato no Akebono was released as an innovative shochu, made by a special method, known as vacuum distillation. Vacuum distillation is a technique that heats the moromi (fermentation mash) in a pot still under low pressure. With low pressure, the boiling point is lowered. The moromi starts boiling at around 45C (113F), resulting in lighter aromatic compounds in the alcohol being distilled earlier to deliver a light and smoother texture and retaining the flavor of its ingredient. Sato no Akebono has been aged for 3 years in stainless steel tanks.
