✨ Technical Specifications
The Aramasa Assortment Case represents the ultimate holy grail for sake connoisseurs, curating a selection of the brewery's most limited, sought-after, and experimental releases. Under the visionary leadership of eighth-generation president Yusuke Sato, Aramasa has redefined modern sake by looking deeply into its past. Each bottle in these highly coveted collections is brewed using 100% traditional Kimoto starter methods, local Akita sake rice, and wooden brewing casks (kioke). Crucially, they rely solely on Kyokai No. 6 yeast, the oldest active strain managed by the Brewing Society of Japan, which was originally isolated at Aramasa in 1930. These assortment cases showcase the breathtaking spectrum of Aramasa's style—marked by a signature wine-like acidity, pristine minerality, and an effervescent freshness that challenges the boundaries of traditional sake.
🍾 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.
