Swiss cheese is a generic term for cheeses modeled on Emmental and related Swiss-type or Alpine cheeses, known for their semi-hard texture and characteristic holes, or "eyes." In North America, the term often refers to a style of cheese that may or may not be made in Switzerland. The category is associated especially with Emmental, Gruyère, Appenzeller, and Sbrinz.

Definition and usage

Swiss cheese is a broad term for cheeses resembling Emmental, particularly yellow, medium-hard to hard cheeses in the Swiss-type or Alpine style. In North America, the name is often generic and does not necessarily mean the cheese was made in Switzerland.

Characteristics

Many Swiss-type cheeses have a mild, nutty flavor and a semi-hard texture. A defining feature in some varieties is the presence of "eyes," which are holes formed during aging by carbon dioxide produced by bacteria.

Major varieties

Well-known Swiss cheeses include Emmental, Gruyère, Appenzeller, and Sbrinz, along with many regional specialties such as Raclette and Vacherin Fribourgeois. Switzerland is reported to produce nearly 500 cheese varieties when fresh cheeses are excluded.

Cultural significance

Cheese is widely described as part of Switzerland's national heritage and, alongside chocolate, an archetypal Swiss food product. Swiss cheesemaking has deep historical roots in Alpine dairy farming and trade.

Key facts

  • Swiss cheese usually refers to cheeses in the Swiss-type or Alpine family, not one single cheese.
  • Emmental is the best-known example and is the cheese most closely associated with the term in North America.
  • The characteristic holes are called "eyes" and are produced by gas formation during cheesemaking.
  • Swiss cheese varieties are produced in many countries, including Switzerland and the United States.
  • Switzerland produces hundreds of cheese varieties, many of them traditional regional cheeses.
