For over a century, Eisen brewed its sake in the heart of Aizu Wakamatsu City. However, as the decades advanced, the brewery's leadership realized that to elevate their sake to a world-class level, they needed a water source of flawless purity. [1, 2, 3, 4]The fifth-generation head brewer spent years scouring the rugged Fukushima terrain. He eventually fell in love with the pristine, sub-surface mountain meltwater at the base of Mt. Bandai. Armed with this ambition, the company made a monumental decision in 1989: they completely packed up their historic urban brewery and relocated deep into the heavy forests at the foot of Mt. Bandai. [1]This high-stakes gamble was validated when their new water source—the Takizawa Spring—was officially registered as one of Japan's 100 Famous Exquisite Waters. Today, the massive, modern-looking facility operates harmoniously inside a dense forest, utilizing this ultra-soft water to craft incredibly smooth, approachable sake. [1, 2]
