Feta is a cheese traditionally made from the milk of goats in Greece, although feta from the milk of cows and sheep is also available. Feta is probably the most famous and important culinary export of Greece, and is popular all over the world, eaten on a wide variety of foods from pizzas to salads. Feta has a distinct briny taste and crumbly texture which is recognizable to a large number of cheese consumers, and it is considered by many to be among the finest of cheeses. A number of nations make feta of their own, although Greece continues to be the largest exporter of the cheese.

Feta is probably one of the earliest known cheeses, and has been manufactured all over the Greek isles for centuries. Homer himself wrote about it, describing how the gods made their cheese. In Greece, most of the land is too rocky and grass is sparse to nourish cattle, who are extremely resource heavy. As a result, many traditional Greek foods rely on the goat, a highly adaptive, intelligent animal well suited to the Greek landscape. In Greece, feta is often eaten as a main course, with many farmers subsisting through long days on blocks of feta eaten with olives.

Because feta is such an important part of Greek culinary history, it has been proposed that the European union apply a protection of designated origin control to some feta cheeses. If the cheese is made in accordance with a set of exacting standards by certain dairies in Greece, it could be labeled as a protected cheese, assuring consumers that they are consuming true feta and an authentic piece of Greek history. This would also ensure that the traditional way of making feta on small farms would be preserved.

Traditionally feta is made with unpasteurized milk which is heated and mixed with rennet to form curds. The curds are drained to remove whey before being cut and wrapped tightly in cheese cloth, which will form the curds into loose blocks of cheese. Under pressure, the blocks firm up, and are placed in brine to cure. Feta is sometimes referred to as a pickled cheese, because it is ripened and matured in brine for six to eight weeks, and will dry up if taken out. True goat feta is very soft, and most of the feta for export is made from the milk of sheep and cows because it holds up much better.

Feta is a pure white, crumbly cheese with a salty, milky flavor. Consumers who dislike the salty taste may soak the cheese in fresh water to leach out some of the salt, or tone down the salt in dishes that feta is used in, allowing the cheese to supply it. Because feta will dry up if taken out of water, it is usually sold packed in water or oil, and should be kept thus packed until use.
