Genshu (undiluted sake)

Genshu (undiluted sake) is sake that is bottled without any water added after the moromi (fermentation mash) has been pressed. As a result, its alcohol content is usually high, typically around 18 to 20 percent, and it is known for a rich, full-bodied flavor. Most sake has water added to adjust the flavor and bring the alcohol level into a suitable range, whereas genshu is bottled in its pure state, allowing drinkers to enjoy its distinctively deep, full texture on the palate. Genshu is also sometimes served on the rocks, and drinking it chilled brings out its flavor further, which makes it especially popular among sake lovers. In terms of production and quality as well, genshu is sold just as it is, without dilution, and in this way it helps convey the purity of sake brewing.
