Most brands of modern soju are made in South Korea. Though traditionally made from rice, most major brands supplement or even replace the rice with other starches such as potato, wheat, barley, sweet potato, or tapioca (called dangmil in Korean). Soju is clear in colour and typically varies in alcohol content from about 20% to about 45% alcohol by volume (ABV), with 20% ABV being most common. Its taste is comparable to vodka, though often slightly sweeter because of the sugars added in the manufacturing process. It is widely consumed, in part, because of its relatively low price.
