Made from fermented rice, sake is a Japanese spirit best enjoyed warm during the cold, snowy months of winter anywhere on Hokkaido. Stop into any izakaya, or Japanese pub, and try a junshu or kunshu sake, two different types served kanshu, or warm. The alcohol content is around 20 percent for most sakes, making it a perfectly pleasant aperitif. Fill your drinking partner’s cup—and they do the same for you—and enjoy the color, aroma, and taste. With more than 1,600 sake producers in Japan, ask the bartender about his or her favorite.
