“YASO GIN”

Fermentation, Aging

It is only us that use the earthen pot made in Jiangsu Province (China) which is famous for the greatest pottery city to ferment and age the extract of wild grasses. It has air permeability because of its countless holes, and fermentative bacteria breathe to improve fermentability. In addition, the pot has an infrared effect, its shape also makes natural convection as unique feature. That brings out the power of the wild grass, mild taste and richness.

発酵の町・上越

The best city for fermentation “JOETSU”

Joetsu district where we produce <80(Yaso)> is the best place for fermentarion, because of its seasonal feature that is ”high temperature and humidity” in summer and “low temperature and humidity” in winter. In addition, we have snow in winter and it varies by 40 degrees throughout the year. Therefore only the very few strong fungi can survive in this situation. We produce enzymes without any temperature or humidity adjustment called “temperature without any artificial control” by making use of the environmental characteristics and our unique fermentation techniques. That enables us to sell products manufactured by only ourselves.
