koshitsukano Shuzou Co.Ltd (越つかの酒造)

Established in 1781 in Agano, Niigata Prefecture, Koshitsukano Shuzo is a venerable brewery that embodies the essence of "Snow Country" brewing. Utilizing pristine spring water from the Gozu Mountains—naturally filtered over decades—the brewery crafts its renowned labels, "Koshika" and "Yoyoyo." Dedicated to the traditional method of "Long-term Low-temperature Fermentation," they nurture their sake during the peak of Niigata’s harsh winters. This process results in the quintessential "Tanrei Karakuchi" (crisp and dry) style: a clean, refreshing texture with a sharp, elegant finish. With over 240 years of heritage, Koshitsukano Shuzo continues to produce sophisticated sakes that harmonize perfectly with delicate cuisines.
