Hakugakusen’s water originates from Mt. Haku, one of Japan's most legendary water sources that has a “GI” status built around the quality of the water . Embarking on a century-long journey, this natural spring water begins as pristine snowmelt atop mountain peaks, gradually filtering through layers of rock before finally descending 100 meters to a natural spring below the brewery. Known for its medium-hard composition, this water serves as the quintessential foundation for Hakugakusen sake, imparting impeccably clean and pure flavors along with a luxuriously smooth, satin-like texture.

Hakugakusen’s sake is designed to pair with the food in Fukui, which is the source of some of the finest seafood in Japan.  The unique brewing process and properties of legendary Mount Haku water give their sake a unique character that the brewer, Yasumoto-san, calls “dancing acidity”.  The mineral-rich water sourced from Mt. Haku provides the fermentation with the nutrients to produce higher acidity levels, that balance the sweetness in the sake.  The brewing process and a proprietary yeast give the acidity some nuance and its presence is very soft in the beginning. However it builds over the course of the sip, creating wonderful interactions with food and with the finish, its acidity spreads across the palate, resetting for the next bite or sip.
