Yukinobousha Yamahai Jyunmai (1.8 L)

Founded in 1902 by Saito Yataro, Saiya Brewery built its kura on a natural six-metre slope in Yurihonjo City, Akita — a layout called Nobori-gura (climbing brewery) that routes rice polishing at the hilltop down through fermentation and pressing by gravity alone, eliminating mechanical agitation at every stage. That structural decision is inseparable from the sake in the bottle.

Water is drawn from a mineral-rich underground spring fed by Mount Chokai (鳥海山), whose snowmelt delivers the soft, clean mineral profile that underpins the house style. The yamahai moto here is the work of toji Takahashi Toichi — recognised by the Emperor of Japan in 2015 as a national artisan — who conducts low-temperature lactic-acid development without wild-microbe intervention, producing a yamahai character that reads as mellow and structured rather than funky or oxidative.

Rice is Akita Sake Komachi polished to 55% remaining (seimaibuai), grown in part by brewery employees themselves — over half the rice supply is employee-farmed, giving end-to-end paddy-to-bottle control that is exceptionally rare. Fermentation proceeds with a proprietary in-house yeast (jikagei kobo), no paddle-stirring, no charcoal filtration, and no water addition, bottled as genshu (undiluted) at natural ABV.

The special feature: yamahai genshu at this polish ratio almost always presents as heavy and rustic — Saiya's no-stir, no-filter, no-dilution discipline produces one that is unusually precise and clean, a direct contradiction of Tohoku's richer regional norm.

As a non-vintage blended expression in the 1.8 L format, this is built for immediate enjoyment and table service; the genshu weight and yamahai acidity give it a drinking window that extends comfortably 2–3 years from purchase when stored cool and dark.
