In France, the appellation d'origine contrôlée (AOC, "controlled designation of origin") is a certification of authenticity granted to certain geographical indications for wines, cheeses, butters, and other agricultural products, under the auspices of the Institut national de l'origine et de la qualité (INAO), based upon the terroir and a form of geographic protectionism.
