Bottle and glass of Jinro sojuSoju (hangul: 소주; hanja: 燒酒), a clear, slightly sweet spirit, is the most popular Korean liquor. It is made from grain or sweet potatoes and is generally inexpensive. It typically varies in alcohol content from about 40 to about 90 proof (from 20 to 45% alc. by volume, respectively).
