TOSATSURU

Three hundred metres below the surface off Muroto, the water has not touched the air for roughly two thousand years.
Tosatsuru has been brewing in Yasuda, Kochi since 1773. In a prefecture whose sake culture runs dry rather than sweet, the house built its reputation on restraint rather than richness.
The brewery draws that deep-sea water, removes the salt, and brews with what is left. The mineral balance drives a strong, clean fermentation — the reason the sake finishes dry without turning thin.
Its record at the National New Sake Appraisal runs to fifty gold awards. That is a measure of consistency over two and a half centuries, not of a single bottle.
The azure bottle was designed by an artist based in London. It was made to sit on a bar in Europe, next to Sancerre and Chablis, and to be judged the way those wines are judged.
Water that spent two thousand years in the dark, in a bottle made to catch the light.
