Jinro Fermentation produces alcohol base (ethanol) through fermentation and distillation, the core raw material for diluted soju, and holds a leading position among domestic alcohol-base makers.
According to disclosed segment data, fermented alcohol base accounts for roughly half of sales, refined alcohol base for more than a third, with hand sanitizer and the company's own Andong Soju traditional distilled liquor making up the remainder.
The domestic alcohol-base market is served by nine producers, including Changhae Ethanol, Jinro Fermentation, Poongkuk Alcohol, and MH Ethanol, whose output is mostly funneled through a single distribution channel, Korea Alcohol Sales Co., before reaching soju makers such as Hite Jinro and Lotte Chilsung Beverage.
This structure traces back to Korea Alcohol Sales Co., established in 1972, which has effectively managed the purchase, sale, and transport of alcohol base for over half a century.
Jinro Fermentation is regarded as one of the more established suppliers within this system, having secured stable volume allocations over time.
Beyond its core business, the company also generates consumer-facing revenue through hand sanitizer, which saw demand following the pandemic, and Andong Soju, its own premium distilled liquor brand.
In brand-reputation rankings of listed domestic beverage companies, Jinro Fermentation has placed within the upper tier, following Hite Jinro, Lotte Chilsung, Muhak, Bohae Brewery, and Changhae Ethanol.
With customers concentrated among large soju producers, the company benefits from revenue stability but carries meaningful dependence on a single downstream industry, diluted soju.
