千兩男山 大吟釀 鴻

Senryootokoyama Daiginjo Ko is a daiginjo from Miyasaka Jozo in Suwa, Nagano, with rice polished to 50% or below to achieve the delicate fruity aromas and highly refined texture the grade demands. The Ko sub-label likely identifies a specific recipe variant within the brewery's daiginjo range, emphasizing precision milling and slow low-temperature fermentation. Suwa's alpine environment and pure mountain spring water provide the mineral clarity that defines premium Nagano sake.
