The Secret Ingredient to Make the Best Sake in the World is…

Located roughly 200 miles (322 km) north of Tokyo, Niigata’s long winters and mountainous terrain have earned it the reputation of being Japan’s “Snow Country”. As the temperature rises after winter, snow from the mountains melts into the Shinano River, the longest river in Japan. The river provides a steady supply of fresh water to the region’s rice paddies, allowing for Niigata to become one of the largest rice producers in the country.

Certain areas of Niigata accumulate over 30 feet (about 9 meters) of snow per year, affecting the brewing process in several ways. First, the runoff water from the mountains creates an ideal climate for growing rice, one of the primary ingredients in sake. That same water source is used in the brewing process, and being that sake is composed of about 80% water, its purity is of the utmost importance. Lastly, the consistently heavy snowfall at a high altitude acts a natural air purifier, ensuring that the water is mostly free from the impurities, germs, and pollutants that can have a significant negative effect on the final product. The end result is a crisp, clean sake, pure as the driven snow.

To maintain its impeccably high standards, Niigata is home to Japan’s first and only Sake Research Institute, an organization whose sole purpose is to further enhance sake brewing methods and quality. The institute continues to develop new varieties of the drink, some of which have been licensed to the region’s major sake breweries and will eventually be available for mass consumption.
