Blue cheese is a general classification of cow's milk, sheep's milk, or goat's milk cheeses that have had cultures of the mold Penicillium added so that the final product is spotted or veined throughout with blue, blue-gray or blue-green mold, and carries a distinct smell, either from that or various specially cultivated bacteria. Some blue cheeses are injected with spores before the curds form and others have spores mixed in with the curds after they form. Blue cheeses are typically aged in a temperature-controlled environment such as a cave. Blue cheese can be eaten by itself or can be crumbled or melted over foods.

In the European Union many blue cheeses such as Roquefort, Gorgonzola and Blue Stilton carry a protected designation of origin, meaning they can bear the name only if they have been made in a particular region in a certain country. Similarly, individual countries have protections of their own such as France's Appellation d'Origine Contrôlée and Italy's Denominazione di Origine Protetta. Blue cheeses with no protected origin name are designated simply "blue cheese".

The characteristic flavor of blue cheeses tends to be sharp and salty. The smell of this food is due both to the mold and to types of bacteria encouraged to grow on the cheese: for example, the bacterium Brevibacterium linens is responsible for the smell of many blue cheeses, as well as foot odor and other human body odors.

History

Blue cheese is believed to have been discovered by accident. The caves in which early cheeses were aged shared the properties of being temperature and moisture controlled environments, as well as being favorable to many varieties of harmless mold. Roquefort is said to have been invented in 1070 AD. Gorgonzola is one of the oldest known blue cheeses, having been created around 879 AD, though it is said that it did not actually contain blue veins until around the 11th century. Stilton is a relatively new addition occurring sometime in the 18th century. Many varieties of blue cheese that originated subsequently were an attempt to fill the demand for Roquefort-style cheeses that were prohibitive due to either cost or politics.
