Tuzemak
Tuzemak, formerly called Tuzemský rum (English: domestic rum), is a term for a traditional Czech distilled beverage. It is a substitute good (ersatz) for true rum which is produced from sugarcane mainly in the Caribbean and Latin America.
Tuzemský is produced from potatoes or sugar beets ethyl formate, diluted and flavoured by various rum essences. In the 19th century similar substitutes were produced throughout the crown lands of the Austro-Hungarian monarchy, which had no access to tropical colonies; they were named Inländer-Rum (like Stroh in Austria), Domači or Čajni (Croatia), Belföldi rum or Hajós (Hungary) etc.
EU regulations allow the name "rum" to be applied only to products made from sugarcane. As a result, from 1 January 2003, this product is sold under other names like "Tuzemák" or "Tuzemský".[1]
