Its best when mixed in a sugar drink, kool-aid, Orange juice, grape juice... Room temp or lightly chilled is the best. Once you mix it like that its very difficult to taste the soju. Soju had a bad side effect of making guys fight, they felt bullet proof, lots of fights in korea after guys drank soju.
Did a tour in korea 91-92, they even have t-shirts that describe the 7 phases of soju. Perhaps someone else remembers the slogan, i can only remember 3 of them, i'll let someone else list them all.
In korea they also have a rice wine, looks like milk...that stuff gets girls soooo horney its awesome. Never saw anyone fight after drinking that milky wine, mostly it made people laugh alot and get frisky.
