Port wine (also known as
Vinho do Porto, ,
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, most notably in
Australia,
France,
South Africa,
Canada,
India,
Argentina, and the
United States. Under
European Union Protected Designation of Origin guidelines, only the product from Portugal may be labelled as
port or
Porto. In the United States, wines labelled "port" may come from anywhere in the world, while the names "Dão", "Oporto", "Porto", and "Vinho do Porto" have been recognised as foreign, non-generic names for wines originating in Portugal.
