Two weeks ago, North Korea claimed it tested a hydrogen bomb, but defence experts believe it was only a boosted-fission bomb. On Tuesday, the communist nation claimed it had developed alcohol that does not give its drinker a hangover.

The hard beverage is made from burnt rice, according to the Pyongyang Times. It uses ginseng roots, a touted miracle drug that North Korea also used in producing alleged cures to Ebola, AIDS and cancer, notes The Telegraph. Ginseng is known for its medicinal qualities and considered an aphrodisiac by many Asian cultures.

The Korean daily reports that the invention was awarded a quality media. By replacing sugar with burnt rice in the production of the alcoholic beverage, North Korean scientists removed the drink’s bitter taste as well as risks of hangover.

The Taedonggang Foodstuff factory took several years in making the perfect alcoholic drink which it named Koryo liquor. Besides the burnt rice, it uses six-year-old Kaesong Koryo insam, which the daily says is known for having the highest medicinal effect.

Insam is a type of indigenous ginseng cultivated using organic farming method. It is mixed with the burnt glutinous rice to produce the brew that “experts and lovers” highly appreciate, according to Pyongyang Times.

But BBC cites Andray Abrahamian, a frequent business traveler to North Korea for Chosong Exchange, who says that while insam liquors are okay and the country has some high-quality liquors, from his experience “there is no such thing as hangover-free booze anywhere in the world.”
