Perhaps the most ubiquitous item in all of South Korea, for better or worse, soju is as much a part of Korean culture and nightlife as sake is to Japan or vodka to Russia. While soju comes in many different shapes, sizes, and flavors, the kind you'll see most is a clear liquid distilled once to about 20% ABV. If you dine like a local while in South Korea, soju should accompany ever dinner, and not just in moderation. If it's not your thing because, well, it's an acquired taste, try somaek as an alternative.
