Olomoucké syrečky (Czech pronunciation: [ˈolomou̯tskɛː ˈsɪrɛtʃkɪ]) or olomoucké tvarůžky ([ˈolomou̯tskɛː ˈtvaruːʃkɪ]) is a ripened soft cheese made in Loštice, Czech Republic, which is very easy to recognize by its strong scent and yellowish colour. It is named after the city of Olomouc. It is made from skim cow's milk without adding rennet colourings, flavourings and stabilizers and contains only 0.6% of fat. Olomoucké tvarůžky is the only original Czech cheese with a distinctive, pungent taste.
The first written mention of this cheese dates back to the 15th century. Olomoucké tvarůžky was eaten by Emperor Rudolf II. Until the 19th century, Olomoucké tvarůžky was produced in the villages surrounding Olomouc, and was generally regarded as a peasant food. It was at this time that the cheese began to be referred to as Olomouc cheese. The A. W. Company has been making this cheese since 1876. There is a small museum devoted to the cheese at the A. W. Company production plant in Loštice.
