Soonhari Yogurt Soju is a clear colorless distilled spirit native to Korea, made from rice, potatoes, sweet potatoes or tapioca and infused with Yogurt flavor. It offers a light sweet, crisp and clean taste with a cool finish. Its special advantages are a lower calorie profile and a lower proof alcohol content. Soju delivers only about half the calories of ordinary vodka while delivering incomparable superior rich taste. As the leader in medium-level alcohol content spirits, soju can be enjoyed straight or it can lend itself as a perfect cocktail ingredient.
