✨ Technical Specifications
Crafted to celebrate the 90th anniversary of the isolation of Kyokai No. 6 yeast at the Aramasa brewery in 1930, this exceptional sake is a tribute to liquid history. It is brewed using Rikuu 132, a legendary heirloom rice variety first developed in Akita Prefecture in 1921. This historic grain is famously intertwined with the legacy of the beloved Japanese poet and agriculturalist Kenji Miyazawa, who passionately advocated for its cultivation due to its resilience against cold weather. Utilizing the traditional Kimoto starter method and fermented in wooden brewing casks (kioke), this sake bridges the past and the present. It delivers a striking profile defined by Aramasa's signature vibrant, wine-like acidity, pristine minerality, and a complex, textured palate that reflects the rustic elegance of the ancient rice strain.
🍾 About the Producer
Established in 1852 by Uhei Sato in Akita Prefecture, Aramasa Shuzo stands as one of Japan's most revolutionary and revered artisanal producers. The brewery earned historic distinction in 1930 when its in-house culture was isolated as Kyokai No. 6, the oldest surviving yeast strain in active distribution. Under eighth-generation kuramoto Yusuke Sato, who took over in the late 2000s, Aramasa embarked on an uncompromising renaissance. Sato committed strictly to pure Junmai brewing, utilizing exclusively local Akita-grown rice cultivated without chemical pesticides, including over 30 hectares farmed in the Uyashinai district. Reviving traditional Edo-period techniques, all fermentations rely purely on indigenous lactic bacteria via the kimoto method and take place entirely in wooden cedar vats (kioke). Fermented using only pristine soft local mountain water and Kyokai No. 6, Aramasa's sakes—such as the iconic unpasteurized No. 6 series, the terroir-driven Colors collection, and the experimental Private Lab bottlings like Amaneko—are globally benchmarked for their electrifying acidity, pristine structural tension, and vinous elegance.
