Namagakoi (storing unpasteurized sake)

Namagakoi refers to the storage of namazake (unpasteurized sake) in its raw state. Because namazake is produced without pasteurization, it is characterized by a fresh flavor and aroma. Storing it in this state allows aging to proceed while preserving the sake's inherent character. Namagakoi is a method practiced especially by sake breweries that value freshness and flavor, and it can be considered an important means of enjoying the appeal of regional sake (jizake). As a result, sake stored by namagakoi often has a more distinct flavor and aroma than usual, and it is recommended to drink it chilled.
