ALTMS = Junmai × Matured at least 3 years

ALTMS means Authentic Long-Term Matured Sake. Junmai (純米) is a term which means sake is made from rice, water, and rice-malt (米麹) only. There is no additional ingredients nor colors. It needs to be matured at least 3 years for obtaining a better taste, texture, aroma and color. Those matured sake obtain a natural amber color which is quite different from newly brewed sake’s color.

ALTMS has been historically enjoyed and consumed by an upper-class.
