Sakekasu

Sake kasu refers to the residue left over from sake production and is a byproduct of rice fermentation. It is an established part of traditional Japanese cuisine, and its fermented character gives it a distinctive, slightly tart flavor.

The term is composed of the kanji 酒 (sake) and 粕 (kasu). The first character refers to the alcoholic rice wine, while the second describes pomace or the solid remains of fermentation. This etymology highlights both the product's origin and its material nature.

Sake kasu is used in a wide range of culinary applications, from marinades to fermented dishes, and is also valued in cosmetics. Traditional production methods and regional differences shape the quality and variety of the final product.
