Compared to other alcoholic beverages, soju is relatively inexpensive. Most bottles of soju actually cost less than similarly sized bottles of beer. Because soju has a higher alcohol content (20% ABV) than beer (5% ABV), this spirit delivers even more value than the typical beer bottle. Less expensive varieties are often diluted and come with fruit flavors. Naturally, other varieties of soju have higher price tags and cost much more than other types of alcohol. If you opt for a more expensive bottle of soju, you typically get a clean flavor with a higher ABV.
