# Emmental cheese

Emmental, Emmentaler, or Emmenthal is a yellow, medium-hard cheese that originated in the Emme Valley in Switzerland. It is classified as a Swiss-type cheese.

## History

Emmental cheese is "true" Swiss cheese; i.e. it originates from the Emme Valley, Switzerland.
It has a savory but mild taste. While "Emmentaler" is registered as a geographical indication in Switzerland, a limited number of countries recognize the term as a geographical indication: similar cheeses of other origins, especially from France (as Emmental), the Netherlands, Bavaria, and Finland, are widely available and sold by that name. In some parts of the world, the names "Emmentaler" and "Swiss cheese" are used interchangeably for Emmental-style cheese.

## Production

Three types of bacteria are needed to prepare Emmental: Streptococcus thermophilus, Lactobacillus helveticus, and Propionibacterium freudenreichii. Historically, the Eyes (holes) were a sign of imperfection, and until modern times, cheese makers would try to avoid them. Nowadays, however, eye formation is valued as a sign of maturation and quality and acoustic analysis has been developed for this purpose. Emmental cheese is usually consumed cold, as chunks or slices, and is also used in a variety of dishes, particularly in gratins, and fondue, in which it is mixed with Gruyère, an other highly popular Swiss cheese.
Ziger, a whey cheese, is a by-product of the manufacture of Emmental.

## Protected varieties and nomenclature

Several varieties of Emmental are registered as geographical indications, including:

### Switzerland

Emmentaler was registered in 2000 as an appellation d'origine contrôlée (AOC) in Switzerland. In 2013, it was replaced by the appellation d'origine protégée (AOP) certification. The Emmentaler produced according to the AOC-registration needs to be produced in small rural dairies with raw cow's milk, adding only natural ingredients (water, salt, natural starter cultures and rennet); preservatives or ingredients from genetically modified organisms are not allowed. The cheese is produced in a round shape with a natural rind, and aged in traditional cellars for a minimum of four months. Emmentaler must be produced in cantons of Aargau, Bern (except Amtsbezirk Moutier), Glarus, Luzern, Schwyz, Solothurn, St. Gallen, Thurgau, Zug or Zurich, or in the See- and Sensebezirk of canton of Freiburg.

### Outside Switzerland

Emmentaler is also recognized as a geographical indication in the Czech Republic, France, Georgia, Germany, Hungary, Jamaica, Portugal, Russia, Slovakia and Spain.
Three cheeses containing the word Emmental are protected under EU law:
* Allgäuer Emmentaler, from Bavaria, Germany, has PDO status
* Emmental de Savoie, from Savoie, France, has PGI status
* Emmental français est-central from Franche-Comté, France, also has PGI status
In many parts of the English-speaking world the terms "Emmentaler" and "Swiss cheese" are both used to refer to any cheese of the Emmental type, whether produced in Switzerland or elsewhere. The United States Department of Agriculture, for example, uses the terms "Swiss cheese" and "Emmentaler cheese" interchangeably.

## Emmental-style cheeses

Emmental cheese is very widely imitated around the world, often just called "Swiss cheese". Specific European types include:
* Grevé from Sweden
* Jarlsberg cheese from Norway
* Maasdam cheese from the Netherlands, with Leerdammer being one variety
