American Viticultural Areas (AVAs) are winegrowing regions with soil chemistry and microclimate distinct from one another. The characteristics of an AVA result in grapes with traits based on those unique factors. Wines made from a grape varietal of one AVA may exhibit different flavors and aromas than a wine made from grapes grown elsewhere.
Oregon has 17 AVAs. About half are sub-AVAs found within larger growing regions. These small-yet-distinct AVAs are one reason Oregon’s wine industry is so specialized, and has become world-renowned for its wines.
Our website organizes wineries in specific AVAs, as well as some general regions, such as areas of the State containing wineries, but perhaps which do not fall within an AVA. Click on a region below to look up wineries and learn more about those areas and their AVAs.
