Feta (Greek: φέτα) is a brined curd cheese traditionally made in countries of the Balkan Peninsula (Greece, Bulgaria, Turkey etc.). A sheep’s milk cheese, varying amounts of goats’ milk may be added, as long as this milk makes up less than 30% of the total mixture.Since 2005, feta has been a protected designation of origin product in the European Union. Outside of the EU, cheeses sold as ‘feta’ may include cow’s milk, or even be composed exclusively of cow’s milk.

Feta is an aged cheese, commonly produced in blocks, and has a slightly grainy texture. It is used as a table cheese, as well as in salads, pastries and in baking, notably in the popular phyllo-based dishes spanakopita (“spinach pie”) and tyropita (“cheese pie”) and combined with olive oil and vegetables.

Similar white brined cheeses (often called ‘white cheese’ in the various languages) are found in the eastern Mediterranean and around the Black Sea.

Feta is salted and cured in a brine solution (based on water or whey) for several months. Feta dries out rapidly when removed from the brine. Feta cheese is white, usually formed into square cakes, and can range from soft to semi-hard, with a tangy, salty flavor that can range from mild to sharp. The cured cheese easily crumbles. Its fat content can range from 30 to 60 percent; most is around 45 percent milk fat. Most feta cheese has a pH of 4.4 to 4.9.

Feta is also an important ingredient of Greek salad. Feta, like most cheeses, can also be served cooked; it is sometimes grilled as part of a sandwich or as a salty alternative to other cheeses in a variety of dishes.
