<P> Portugal's Denominação de Origem Controlada, Austria's Districtus Austria Controllatus, South Africa's Wine of Origin, and Switzerland's AOC - IGP are all similar to the French AOC system as well . </P> <P> It appears also that AOC influenced the development of the European Union's protected designation of origin (PDO) system . </P> <P> Switzerland has an appellation d'origine contrôlée certification for wines and an appellation d'origine protégée certification for other food products . Before 2013, the appellation d'origine contrôlée was used for all products . </P> <P> The United States' American Viticultural Areas also follows the model set by the French AOC . The United States Department of the Treasury's Alcohol and Tobacco Tax and Trade Bureau even uses the legal terminology "Appellation of Wine Origin" to describe a vintage wine's location of origin . The AVA indication on a label indicates that 85% of the grapes for wine are grown in the designated AVA . Overall, the appellation of a wine simply says where the grapes are from, although there are some particularities . If the appellation is a state, 100% of the grapes which go into the wine must come from the specific state . If a winery gets grapes from a neighboring state (for example, a California vintner getting Pinot noir from Oregon), it may label the wine "Oregon", but if the state is not a neighboring one (for example, a California vintner getting Cabernet from Washington state), the only permitted appellation is "American ." </P>
