Founded in 1665, this sake brewery is located in Ueda City, Nagano Prefecture, a historic post town along the Shinshu Kaido. The brand has been loved by the local community for many years. It has always pursued a rich, vibrant sake with a sweet, aromatic flavor that satisfies in just one glass. The brewery has not only reviewed its brewing process but also made significant investments in facilities, including the renovation of its koji room and the introduction of refrigeration. As a result, the sake has evolved from a mellow, traditional style to a fresh, fragrant one. The brand gained a rapidly growing fan base, especially in Tokyo, and became known for its unforgettable taste. Today, production has increased from 30 koku ten years ago to 500 koku, and Shinshu Keirei has become a sought-after name among sake enthusiasts, widely recognized as a rare and hard-to-find brand.
