Dassai Junmai Daiginjou 50 (300 ml)

When Hiroshi Sakurai launched the Dassai brand in 1990, he made a commitment virtually without precedent in Japanese brewing: every single expression in the range would be Junmai Daiginjo — no futsushu, no honjozo, no compromise grades. The 50 (seimaibuai 50%) is where that philosophy begins. Brewed year-round by permanent staff in a 12-story facility deep in the mountain valley of Shuto-cho, Iwakuni City, Yamaguchi Prefecture, it draws on the region's celebrated soft Seiryu-classified water — low in minerals, purified further on-site — which allows the delicate aromatic compounds of Yamada Nishiki rice to resolve without interference from hardness or iron. 100% Yamada Nishiki, polished to exactly 50% of the original grain, is washed in 10 kg batches under running water and soaked for approximately 15 minutes; koji is applied entirely by hand. Fermentation runs in small individual tanks with temperature carefully managed through the moromi stage, while two parallel brewing teams simultaneously test differing water-absorption rates and fermentation temperatures — a data-driven artisan model that replaces the traditional seasonal toji system entirely. The defining technical signature: Dassai pioneered commercial centrifuge pressing in Japan (c. 2000), separating sake from mash without applied pressure to preserve the most volatile aromatic fractions intact. Pasteurization follows the proprietary Hayata method (Patent 2013-008455) — bottled cold below 5°C, hot-shower pasteurized, then immediately rapid-cooled. The result is a Junmai Daiginjo of uncommon textural clarity at its price point, with ripe pear, lychee, and melon aromatics that owe their precision to centrifuge extraction rather than conventional pressing.
