Fukugao Sake Brewery's bourbon barrel-aged sake represents a novel style with distinctive flavors and aromas. Aged in charred bourbon barrels from Kentucky, this sake acquires deep sweetness with notes of roasted coffee and vanilla. Founded in 1897 in Sanjo City, Niigata, the brewery combines traditional sake-making methods with innovative barrel aging techniques. The result is a unique blend where sake's umami meets bourbon's characteristics, creating a smooth, rich flavor profile with subtle sweetness and gentle acidity. This sake can be enjoyed either chilled or on the rocks, living up to the brewery's name meaning "face of happiness."
