Every year, the trade magazine Drinks International puts out a list of the top-selling alcohols in the world, and in the category of spirits, there is one brand that more than doubles the sales of its closest competitor every year. Smirnoff, Jack Daniel's and Bacardi don't even come close. That top-seller is South Korea's Jinro soju, a clear spirit traditionally made of rice. It's about 20-percent alcohol and has a light, slightly sweet taste.
