Snow-stored Sake

In 1987, we became the first brewery in Japan to age sake in tanks buried deep in the snow.
A unique maturation process occurs when we store the freshly strained raw sake, resulting in a softly enhanced umami flavor with the original freshness intact.

Snow purifies the air.
Clean air is essential for sake brewing, as it uses microorganisms such as koji and yeast.
The cold winters in Ojiya, Niigata, are also stable, with high humidity and low temperatures.
The temperature in the storehouse remains nearly constant at around 5°C throughout the day, with no significant temperature fluctuations.
Sake brewed at low temperatures for an extended time under the care of the toji (master brewer) and other brewers develops a gentle and pure character.

The Koshino Hatsuume Snow-stored Sake is crafted by the superior skills of the Echigo Toji and their masterful use of the unique snow-country environment, resulting in a soft, delicate, “light and mellow” flavor.

This refined sake is brewed by fully harnessing our blessed environment.
