Balkánský sýr (English: [[Balkan]] cheese) is a type of white brined cheese produced from cow's milk in Czech Republic and Slovakia. It is a salty semi-hard white cheese, analogous to Bulgarian sirene, and Greek feta. It is usually not matured (Czech: nezrající).
It is mainly used as a substitute of sirene in the Bulgarian shopska salad[1] or instead of feta in greek salad.
