✨ Technical Specifications
Aramasa's 'Colors' series is an avant-garde exploration of Akita Prefecture's heritage sake rice varieties, brewed using traditional wooden casks (kioke) and the historic Kyokai No. 6 yeast. The 'Cosmos' expression is dedicated entirely to Kairyoshinko, a rare and temperamental sake rice first registered in Akita in 1959, celebrated for its elegant, earthy, and botanical flavor profile. The 'Direct Pump' (Jikagumi) designation refers to a highly meticulous bottling process where the sake is drawn directly from the press under pressure. This technique captures the natural carbon dioxide produced during fermentation, resulting in a pristine, delicate effervescence that enhances the sake's vibrant, wine-like acidity and mineral-driven structure.
🍾 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.
