Junmai Daiginjo 'mine' Reaches 150 Restaurant Adoptions

Azumino Mineral Water Co., Ltd. (Headquarters: Azumino, Nagano; Representative Director: Yasunori Arai) is pleased to announce that its Junmai Daiginjo sake 'mine,' which utilizes the company's natural water, has reached 150 adoptions in restaurants and lodging facilities. 'mine' is a Junmai Daiginjo brewed by transporting natural water from Azumino to a long-established brewery in Fushimi, Kyoto, and has been expanded through direct proposals to restaurants rather than through liquor wholesalers. For many years, as a beverage manufacturer handling natural water from Azumino, our company has focused on the value and quality of water. Representative Arai believed that Azumino's water held a value that could be conveyed more deeply, and 'mine' was born from that question. As a company without its own brewery, we collaborated with Shotoku Shuzo, which has over 300 years of history in Fushimi, Kyoto, to create sake that only a water company could produce. 'mine' uses non-heated natural mineral water filtered through high-precision microfilters. It is the only Junmai Daiginjo in the world that uses this water not only for brewing but also for rice soaking and alcohol content adjustment. Since the first brewing in 2021, we have produced limited quantities each year, carefully delivering them to restaurants. Furthermore, 'mine 12%' received a Platinum Award at the 'Kura Master 2026' sake competition in France, proving its quality from the perspective of European food culture. We will continue to expand its value domestically and internationally, focusing on Nagano Prefecture and the Tokyo metropolitan area.
