Kirinzan Classic (720 ml)

When the Saito family pivoted from charcoal manufacturing to sake brewing in 1843, they chose a site at the foot of Mt. Kirinzan in Aga-machi — a decision that locked in the brewery's defining raw material: exceptionally soft, low-mineral water drawn from the Tokonami River basin, filtered through dense beech forest soils. That water chemistry is not incidental; it slows fermentation, suppresses harsh acids, and produces the clean, dry finish that defines Niigata's Tanrei Karakuchi school. Kirinzan Classic is built on a blend of Gohyakumangoku and Koshi-ibuki rice, milled to 65% seimaibuai, fermented with the brewery's proprietary G901 yeast via the sokujo moto starter method and extended cold fermentation. Tank-aged in stainless steel and pasteurized before bottling at 15–16% ABV, it is diluted to standard strength — no genshu concentration. The transgression here is deliberate: Kirinzan treats this entry-level futsushu as a serious craft expression of local terroir, sourcing all rice from within 10 km of the brewery through 55 contracted Aga-machi growers — a 30-year supply-chain project that most prestige breweries reserve only for their flagship tiers. The result is a razor-sharp, lightly umami-framed dry sake that performs across a wide temperature range.
