Eisen Shuzo traces its lineage to 1869 in the Aizu region of Fukushima, a landlocked basin whose cold winters and distinct four-season climate have long produced distinctive, full-flavored sake. In 1988 the brewery relocated to the western foot of Mount Bandai, giving it direct access to Ryugasawa Spring, officially designated one of Japan's 100 Best Water Sources by the Environment Agency, and the spring's name became the brand's identity. The Junmai Ginjo Genshu Cho Karakuchi is brewed from locally grown Toyonishiki rice and Fukushima yeast, pressed at full strength without dilution (genshu) and skewed strongly toward the dry end of the flavor spectrum. The combination of volcanic-filtered spring water, high alcohol undiluted body, and a dramatically negative sake meter value makes this a sake of intensity and precision.
