Bryndza or brynza is a sheep milk cheese made across much of East-Central Europe, including in Ukraine and Slovakia. Bryndza cheese is creamy white in appearance, known for its characteristic strong smell and taste. The cheese is white, tangy, crumbly and slightly moist. It has characteristic odor and flavor with a notable taste of butyric acid. The overall flavor sensation begins slightly mild, then goes strong and finally fades to a salty finish. Recipes differ slightly across countries.

Sheep's milk is the milk of domestic sheep. It is commonly used to make cultured dairy products, such as cheese. Some of the most popular sheep cheeses include feta (Greece), ricotta (Italy), Roquefort (France) and Oscypek (Poland).
