Port wine (also known as Vinho do Porto, Porto, and often simply Port) is a Portuguese style of fortified wine originating from the Douro Valley in the northern provinces of Portugal. It is typically a sweet red wine, often served as a dessert wine, and also comes in dry, semi-dry and white varieties. Fortified wines in the style of port are also produced outside of Portugal, most notably in Australia, South Africa, Canada, India, Argentina and the United States. Under European Union guidelines, only the product from Portugal may be labeled as Port. Elsewhere, the situation is more complicated: wines labelled “Port” may come from anywhere in the world, while the names “Dao”, “Oporto”, “Porto”, and “Vinho do Porto” have been recognized as foreign, non-generic names for wines originating in Portugal.
