Soju is originally from Korea, where it was first distilled around the 14th century. Unlike vodka, soju has a natural hint of botanicals that can make for a smoother taste as opposed to vodka, which can sometimes come off as harsh at the end. It is also not only lower in calorie than vodka, but it is also lower in proof. This grapefruit flavored soju is very fruity and smooth. It’s a little sweeter and not as harsh as regular soju, with alcoholic content at 13%.
