Soju

Soju is a clear and colorless distilled alcoholic beverage, traditionally made from rice, but later from other grains and has a flavor similar to vodka. It is usually consumed neat. Its alcohol content varies from about 12.5% to 53% alcohol by volume (ABV), although since 2007 low alcohol soju below 20% has become more popular. Traditionally, most brands of soju are produced in the Andong region, but also in other regions and countries. While soju was traditionally made from rice, South Korean ethanol producers replace rice with other starch, such as cassava due to significantly lower capital costs. Soju often appears similar to several other East Asian liquors while differing in alcohol contents.
