✨ Technical Specifications
To celebrate their landmark 170th anniversary in 2022, Aramasa Shuzo crafted this highly limited masterpiece using Kairyoshinko, a legendary local Akita sake rice first registered in 1959. This heirloom grain, which had nearly vanished from commercial cultivation, was painstakingly revived by Aramasa to express the true, historic terroir of Akita. Brewed using their signature Kyokai No. 6 yeast—the oldest active sake yeast strain in Japan, which was originally isolated at Aramasa in 1930—and fermented in traditional cedar wooden casks (kioke) using the ancient Kimoto starter method, this sake is a bridge between past and future. The result is a profoundly complex profile that marries vibrant, wine-like lactic acidity with deep umami, delicate woody undertones from the cedar, and a pristine, mineral-driven finish that redefines modern sake craftsmanship.

Under the avant-garde leadership of eighth-generation owner Yusuke Sato, the kura strictly champions traditional, natural brewing methodologies, utilizing only native Akita rice cultivars, wooden fermentation vats (kioke), and the time-honored kimoto method without additives.
