Port wine (also known as vinho do Porto, Portuguese pronunciation: [ˌviɲuduˈpoɾtu], Porto, and usually simply port) is a Portuguese fortified wine produced exclusively in the Douro Valley in the northern provinces of Portugal. It is typically a sweet, red wine, often served as a dessert wine, though it also comes in dry, semi-dry, and white varieties. Fortified wines in the style of port are also produced outside Portugal, including in Australia, France, South Africa, Canada, India, Argentina, Spain, and the United States. Under European Union Protected Designation of Origin guidelines, only the product from Portugal may be labelled as portor Porto. In the United States, wines labelled "port" may come from anywhere in the world, while the names "Oporto", "Porto", and "Vinho do Porto" have been recognised as foreign, non-generic names for port wines originating in Portugal.
