Junmai Ginjo Asagao Label (720 ml)

Eikofuji's Asagao Label represents a lineage rooted in Matsumoto, Nagano Prefecture, where the Japanese Alps moderate temperature swings and mineral-rich groundwater feeds the brewing tradition. The brewery's name itself—Eikofuji—carries historical weight in the region's sake genealogy.

This Junmai Ginjo employs a 40% polish ratio (seimaibuai), removing 60% of the outer grain layers to expose the starch-rich core. The Asagao designation (morning glory) signals the brewer's aesthetic intent: a sake of delicate, ephemeral character. Fermentation parameters and water source leverage Matsumoto's elevation and mineral profile, typical of alpine sake production where cooler conditions extend yeast activity and refine aromatic development.

The floral nomenclature is not marketing flourish but a technical outcome: ginjo-class polishing and cool-region fermentation naturally elevate volatile esters, the aromatic compounds responsible for the sake's signature profile. This expression drinks cleanly, with restrained sweetness and a mineral backbone characteristic of Nagano's groundwater chemistry.

Optimal drinking window: within 1–2 years of release to preserve aromatic volatility.
