Kǔ Soju is traditional Korean liquor distilled from sweet potato, Kǔ Soju has a velvety, lightly sweeten, crisp and clean taste better than that of premium vodka. In Asia , soju is traditionally enjoyed straight, chilled, or on the rocks with meals. In the U.S. , however, soju is gaining in popularity as a base for cocktails because, like vodka, it is highly versatile and blends extremely well with fruit juices, soft drinks, and traditional bar mixers.
