Soju has long held an integral place in South Korea's drinking culture. In recent years, however, a new trend has swept the country—zero-sugar soju. This transformation of the traditional drink has been welcomed by health-conscious consumers looking to enjoy their favorite spirit without the guilt of sugar consumption. But the question arises, is zero-sugar soju truly a health-friendly alternative or just another foe masquerading as a friend?


The Rise of Zero-Sugar Soju

The zero-sugar soju trend began in earnest in 2019, when local liquor company Daesun launched its Good Day Soju. This novel product was quickly followed by Daesun Distilling's sugar-free soju, marking the start of a new era for the drink. The most notable addition came recently when Hite Jinro, the local liquor company with the largest market share, decided to relaunch its entire Jinro Soju product line without sugar. Its counterpart, Lotte Chilsung Beverage, also entered the race with its sugar-free soju, Chum Churum Saero—colloquially known as Saero (새로)—which became an instant sensation, selling over 30 million bottles in just a few months.


The push toward this trend didn't happen in isolation. The Ministry of Food and Drug Safety and Fair Trade Commission encouraged liquor companies to post nutritional content, including calories, on their bottles. This move was aimed at promoting transparency and enhancing consumers' right to knowledge, as alcohol is often blamed for various health issues. Major soju brands responded to this by not only providing nutritional information but also drawing consumers' attention with flashy zero-sugar labels, which quickly became a sign of healthier vice.


These changes have undoubtedly had a significant impact on the market. The promise of zero-sugar, coupled with engaging marketing campaigns—like Hite Jinro's slimmed-down toad mascot—has appealed to consumers, particularly those with health-conscious mindsets. However, as we move through this analysis, it's essential to understand what "zero-sugar" really means and how it affects the overall nutritional profile of the beloved soju.


Understanding the Caloric Intake

Even with the sugar eliminated, it's important to recognize that soju is still high in calories—only 100 calories shy of a McDonald’s Big Mac. The traditional soju packs an average of 408 calories per 360-milliliter bottle—more than triple the amount found in a can of beer. The zero-sugar versions do have fewer calories, but they still contain an average of 326 calories per bottle. Here's how that compares with other popular alcoholic beverages:

  • Soju: 408 calories per 360ml

  • Zero-sugar soju: 326 calories per 360ml

  • Red wine: 300 calories per 360ml

  • Makgeolli (Korean traditional rice wine): 178 calories per 360ml

  • Beer: 170 calories per 360ml

Even the zero-sugar soju has higher calories than red wine, makgeolli, and beer.


The Hidden Factor: Alcohol Volume

While the focus has been on the zero-sugar aspect of these new soju brands, another factor that often goes unnoticed is the reduction in alcohol by volume (ABV). Traditional soju generally has an ABV of around 16%, but the four zero-sugar brands have all slightly reduced their ABV:

  • Saero and Jinro Soju: Reduced from 16.5% to 16%

  • Daesun and Good Day Soju: Reduced from 16.9% to 16.5%

This reduced alcohol content plays a significant role in the lower calorie count of zero-sugar soju. For comparison, one gram of pure alcohol amounts to seven calories, and drinks with higher alcohol content naturally have more calories.


It is undeniable that the reduction in sugar and alcohol content has led to a lower-calorie soju option. However, it's important to remember that these drinks still provide a substantial number of calories. Moreover, as Cheong Chul, an industry studies professor at Seoul Venture University, warns, these are "empty calories." While zero-sugar soju provides calories, it lacks the carbohydrates, proteins, fats, vitamins, and minerals necessary for basic nutritional metabolism. As a result, consuming too much of it can lead to excessive calorie intake, which, if not burned off, can lead to fat storage in the body.


So, while zero-sugar soju may be a friend to those seeking a lower-sugar, lower-alcohol beverage, it should not be mistaken for a health drink. Moderation, as always, is key.


The Evolution of Soju and Market Response

  • Soju's alcohol content has been on a steady decline for many years. The first soju by Jinro, Korea's first liquor company, had an ABV of 35 percent in 1924. It dropped to 30 percent in 1965 and 25 percent in 1973. Nowadays, soju typically has around 16 percent ABV, with slight variations depending on the brand.

  • Zero-sugar soju has found a receptive market. For instance, Lotte Chilsung Beverage's sugar-free soju, Chum Churum Saero, has gained considerable popularity, selling over 30 million bottles from its market introduction in September to December of the same year.

  • Consumers report enjoying the "lighter" and "cleaner" taste of zero-sugar soju. Many have found that the lower alcohol content and absence of sugar result in a milder alcohol aroma and smoother drinking experience.

Zero-Sugar Soju and Weight Conscious Drinkers

  • As weight consciousness increases, zero-sugar soju appears to be an appealing option. People appreciate that they can enjoy their favorite liquor with fewer calories and less sugar.

  • But it's vital to recognize that while the sugar content is zero, the drink itself still has a considerable number of calories. Consumption should be mindful, especially among those tracking their calorie intake.

The Final Verdict


In conclusion, zero-sugar soju appears to be both a friend and a foe. It's a friend because it offers a slightly healthier alternative for soju lovers who are conscious of their sugar and alcohol consumption. It provides a milder, smoother, and cleaner taste that appeals to many drinkers.


However, it can also be a foe if its reduced sugar and alcohol content misleads people into believing it's a 'healthy' drink. Despite the lack of sugar, zero-sugar soju still delivers substantial 'empty calories' and, when consumed excessively, can contribute to an excess calorie intake and potentially lead to weight gain.


As with any alcoholic beverage, the key to enjoying zero-sugar soju is moderation. It's crucial to remember that while it might be a slightly better option than its traditional counterpart, it is by no means a health drink.
