Tōshun Brewery, the maker of the "Azumaryu" brand, continues to pursue the perfect balance of richness, sharpness, and fragrance by faithfully preserving the traditional yamahai brewing method passed down through generations. They carefully select premium sake rice varieties such as Yamada Nishiki, Yume Ginka, and Gohyakumangoku, and use pristine spring water drawn from a well fed by the Kiso River. Over the years, they have sought out the ideal yeast strains and brewing methods suited to their environment, honoring the intricate elements of koji, fermentation, and traditional techniques. This dedication has resulted in sake that is both elegant in aroma and deep in flavor. While committed to innovation, they also take pride in preserving the time-honored yamahai style, which yields sake known for its depth, umami, and clean finish. Tōshun Brewery approaches sake-making with sincerity, never settling for the status quo. Each year, they carefully assess the quality of the rice and behavior of the yeast to ensure their sake reaches its highest potential.
