Emmentaler

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