Chamisul Fresh is Korea’s No. 1 soju brand. With a 7-step refinement process using active bamboo charcoal, the substance that causes hangovers is removed so only the fresh, clean finish remains. Feel clearheaded and ready for action when you wake up. Chamisul Fresh uses only clean vegetable additives such as Finnish fruit sugar, known as a “healthy sugar,” and Tomatin, a protein sweetener extracted from the black seeds of katemfe grown in West Africa.
