✨ Technical Specifications
The 'No. 6' series from Aramasa is a legendary lineup in the sake world, celebrated as the only recurring unpasteurized (Nama) release from this historic Akita Prefecture brewery. The 'R-Type' (standing for 'Regular') serves as the essential introduction to this avant-garde collection. Brewed using the traditional Kimoto starter method in wooden casks (Kioke), it is defined by the exclusive use of Kyokai No. 6 yeast—the oldest surviving strain of the Brewing Society of Japan, which was originally discovered on-site at Aramasa in 1930. This sake represents a revolutionary bridge between ancient craftsmanship and modern, wine-like sensibilities, offering a delicate natural effervescence, pristine minerality, and a bright, lactic acidity that challenges traditional sake conventions.
🍾 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.
