Feta is a Greek brined white cheese made from sheep's milk or a mixture of sheep and goat's milk. It is soft, with small or no holes, a compact touch, few cuts and no skin. Crumbly with a slightly grainy texture, it is formed into large blocks and aged in brine. Its flavour is tangy and salty, ranging from mild to sharp. Feta is used as a table cheese, in salads such as Greek salad, and in pastries, notably the phyllo-based Greek dishes spanakopita "spinach pie" and tyropita "cheese pie". It is often served with olive oil or olives, and sprinkled with aromatic herbs such as oregano. It can also be served cooked (often grilled), as part of a sandwich, in omelettes, and many other dishes.
Since 2002, feta has been a protected designation of origin in the European Union. EU legislation and similar legislation in 25 other countries limits the name feta to cheeses produced in the traditional way in mainland Greece and Lesbos Prefecture, which are made from sheep's milk or from a mixture of sheep's and up to 30% of goat's milk from the same area.
Similar white brined cheeses are made traditionally in the Balkans, around the Black Sea, in West Asia and more recently elsewhere. Outside the EU, the name feta is often used generically for these cheeses.
For many consumers, the word feta is a generic term for a white, crumbly cheese aged in brine. Production of the cheese first began in the Eastern Mediterranean and around the Black Sea. Over time, production expanded to countries including Denmark, France, Germany, Italy, the UK and the USA, often partly or wholly of cow's milk and they are (or were) sometimes also called feta. In the US most cheese sold under the name feta is American and made from cows' milk.
Since feta 2002 feta has been a PDO product within the EU. According to the relevant EU legislation (applicable within the EU and Northern Ireland), as well as similar UK legislation only those cheeses produced in a traditional way in particular areas of Greece, which are made from sheep's milk, or from a mixture of sheep's and up to 30% of goat's milk from the same area, can be called feta. Also in several other countries the term feta has since been protected.
