This traditional Czech drink was invented in the 19th century as a substitute for the original Caribbean rum. It is usually distilled from potatoes or sugar beets to create a base that is then enriched with rum essence. The drink was initially classified as rum and carried the name tuzemský rum (domestic rum), but since it is not distilled from sugarcane, European regulations prohibited its original name and classification. Tuzemák is still produced in the same way, and it is a staple drink across the country.
