Ilaka Sake Atelier Silver-Indigo

Silver-Indigo (Gin-Ai) is the driest, most austere member of Ilaka Sake Atelier's five-bottle Silver series, brewed with a legendary "P33" yeast strain revived from decades of deep-freeze (-80°C) storage. Where Silver-Black leans soft and approachable, Silver-Indigo is built for sharpness: a refreshing nose of grapefruit and crisp green bamboo leads into a light-umami, cutting dry palate, tightened by fine natural effervescence and a pleasant bitter astringency on the finish. Brewed in Matsukawa Village, Nagano, using the brewery's signature ultra-soft Northern Alps spring water and locally grown rice, pressed at sub-zero temperatures to preserve its aromatics. Ilaka Sake Atelier revived a 1665-founded kura under master brewer Katsumi Tanaka, launching in November 2024 and winning an IWC 2025 Gold Medal for its very first vintage.
