The term “appellation” varies slightly from country to country, but in the more basic sense, it is the region in which a wine was produced. The term “AVA” (American Viticultural Area) is the North American equivalent of the word ‘appellation’ and refers to a specific growing region.
Oregon has 17 official AVAs and several new ones are currently under review for consideration.
Though some wineries and vineyards are located outside of these regions, the majority of Oregon wines can be classified under a regional AVA.
Wines produced with grapes originating from more than one of these AVAs may simply be labeled as an Oregon wine.
