Tasting Notes

The term Kongoshin, meaning "a firm and stable mind," is perfectly embodied in this supremely noble brew. After two years of meticulous aging, it unveils a remarkably smooth, crystalline profile with profound depth and an impossibly elegant mouthfeel. As an undiluted Genshu (17.8% ABV), it carries a rich, satisfying weight that resolves into a pristine, clean finish. This exclusive sake is a phenomenal companion for refined cuisine, pairing beautifully with salt-grilled anago (sea eel), delicate white fish mousse, and rich salmon simmered in sake kasu.
