[Inside Chodong] The Identity Crisis of Korea's "National Liquor" Soju

Major manufacturers lower soju’s alcohol content to the 15% range

A nearly 20-percentage-point drop in 100 years since its debut in 1924

The nation's favorite liquor, soju, keeps getting milder. Earlier this year, Lotte Chilsung Beverage lowered the alcohol content of “Saero” from 16% to 15.7%, after about three years on the market. HiteJinro also reduced the alcohol content of “Jinro Is Back” and “Chamisul Fresh” by 0.3 percentage points each, bringing both down to 15.7%. This follows the lowering of Lotte Chilsung Beverage’s flagship soju, “Chum Churum,” to 16% last year, setting a clear trend toward sojus in the 15% range dominating the market.

When the original distilled soju was first introduced by the old Jincheon Brewing Cooperative (now HiteJinro) in 1924, it had an alcohol content of 35%. In the 1960s, production methods shifted to diluting neutral spirits with water, gradually lowering the alcohol content—dropping nearly 20 percentage points over roughly 100 years. The market now offers soju with alcohol levels in the 14% range, and there are lighter versions with fewer calories and a content as low as 11.7%.

Major manufacturers say that lowering the alcohol content of soju reflects the overall trend toward lower-strength liquors in the market and demand from consumers who prefer a cleaner taste. This was an effective strategy up until the COVID-19 pandemic, when group gatherings and after-work drinking sessions were frequent and often extended late into the night. The milder taste and less pronounced intoxication, even when finishing a whole bottle, had consumers drinking larger amounts than before.

After the transition to “endemic” status for infectious diseases, however, the market dynamics have shifted. Younger consumers, in particular, now prefer solo drinking (“honsul”) or drinking at home (“homesul”) over group drinking, and their interest has spread to a diverse range of alcoholic beverages such as highballs and wine. Even as soju becomes milder, this does not directly translate into higher sales as it may have in the past.

According to the National Tax Service’s statistics portal, domestic shipments of diluted soju dropped 13.4%, from 916,000 kiloliters in 2019 before COVID-19 to 793,000 kiloliters last year. Shipments bounced temporarily to 862,000 kiloliters in 2022, up 4.3% year-on-year, as society shifted to an endemic phase, but have since resumed a downward trend. In short, even riding the lower-alcohol trend has not stopped soju sales from declining.

Ultimately, the competition to offer milder soju appears to be a survival strategy aimed at reducing production costs for manufacturers. With the government’s firm stance on price stability and these products being highly price-sensitive among consumers, companies are seeking to restrict ex-factory price hikes by reducing spirits usage wherever possible. According to industry sources, lowering the alcohol content by 0.1 percentage points can reduce the spirit cost by around 0.6 to 0.9 won per bottle. While the savings per bottle are negligible, considering that large manufacturers sell up to 2 billion bottles annually, the cumulative reduction in costs is significant.

In the meantime, soju’s position in the market has become less clear. The rise of mixology culture means that mixing alcoholic beverages has become the domain of high-proof liquors like whisky, and soju’s alcohol content now overlaps with wine, which averages 13–15%. The market is also flooded with low-alcohol alternatives like non-alcoholic beverages and fruit-flavored distilled spirits. The weaker soju becomes, the more its identity is diluted, which could become grounds for consumer backlash if companies attempt to raise prices in the future. Instead of focusing only on testing the lowest limits of alcohol content, manufacturers may need to reconsider how to restore and reinforce soju’s own unique identity.
