Gruyere ( or ; ] , German: "Greyerzer") is a hard yellow cheese, named after the town of Gruyeres in Switzerland, and originated in the cantons of Fribourg, Vaud, Neuchatel, Jura, and Berne. Before 2001, when Gruyere gained the "appellation d'origine controlee" (AOC, now AOP) status as a Swiss cheese, some controversy existed whether French cheeses of a similar nature could also be labelled "Gruyere" (French Gruyere style cheeses include Comte and Beaufort).
