Genshu (undiluted sake) – A toji controls when to stop fermentation at a certain alcohol level to achieve his desired flavor profile.  Sake can be fermented to an alcohol level up to about 20-21%, and is usually controlled to around 16-18%.   Normally, pressed sake is then diluted by adding water to the desired bottling level around 15-16% which is most suitable for drinking.  Some brewers, however, may want to present the undiluted sake at the fermented level without adding additional water.  This is referred to as genshu sake, or “original sake.” Genshu sake tends to have a much stronger and richer flavor profile

Ginjo – premium sake made with rice with a polishing ratio of 60% or less.

Happoshu – sparkling sake (also known as awazake) can be made via carbonation or through a secondary fermentation process in the bottle.  Sparkling sake is relatively new, and has seen an increase in supply and demand worldwide.  The style is likened to champagne-style, and can run from sweet styles to dry styles.

Hiire – pasteurization.  Sake is usually pasteurized to kill off microorganisms and also to deactivate amylase, protease and other enzymes to improve storage stability.

Hiyaoroshi – a namazume sake normally released each autumn.  Namazume is sake that is pasteurized once right before storage. Sake is normally stored for 3-12 months or more before bottling and shipment.
