Funaguchi is an un-pasteurized and un-diluted type of Sake and as such it is surprisingly delicate. The most damaging elements to the quality of sake particularly un-pasteurized type are light, heat and the air. So in order to deliver the unique taste of freshly brewed Sake, the aluminum can, which completely block out the light, are right to the top to reduce the amount of air that could come into contact with the Sake. This way they could protect this delicate type of Sake allowing more people to enjoy the flavor of pure Sake previously only available to those lucky enough to visit the brewery.
Funaguchi has a rich, full-bodied flavor yet with a refreshing clean finish. unlike conventional sake (diluted with water to reduce alcohol down to around 15%), funaguchi is un-diluted,cask strength whopping 19% abv, making it a all-around performer from chilled&up,frozen, on the rocks, or mix into cocktails!
