Tsuchida 12 (720 ml)

When 6th-generation owner Yuji Tsuchida deliberately dismantled his predecessor's ginjo-focused, high-polish programme, he reached back to Edo-period kimoto technique — and then pushed further, bottling Tsuchida 12 at a naturally low 12% ABV without water adjustment, a rarity in a category where dilution to target strength is standard practice. The brewery sits at the southern foot of Mt. Hotaka in Kawaba Village, Gunma's northern highlands, drawing on spring water that has filtered underground for approximately 50 years before reaching the brewery — mineral-laden, soft, and structurally suited to slow fermentation. That cool mountain microclimate extends fermentation time to roughly twice the modern norm. The rice is Asahi no Yume, a Gunma-grown edible table rice polished to only 90% seimaibuai — retaining the bran layers, amino acids, and lipids that premium sake rice is typically stripped of. Fermentation proceeds via full kimoto method, with ambient lactic acid bacteria from the brewery air building the shubo naturally; no manufactured lactic acid is added, a practice used by fewer than 1% of Japanese producers. The result carries pronounced rice-grain umami, natural lactic tang, and a savoury depth that the ginjo mainstream cannot replicate. What is singular here: Tsuchida 12 achieves its low alcohol not through dilution but through fermentation design — the combination of minimally polished table rice and kimoto biology simply produces a lighter-bodied, lower-ABV sake without intervention.
