Port wine (Portuguese: vinho do Porto, Portuguese: [ˈviɲu ðu ˈpoɾtu]; lit. 'wine of Porto'), or simply port, is a Portuguese fortified wine produced in the Douro Valley of northern Portugal.[1] It is typically a sweet red wine, often served with dessert, although it also comes in dry, semi-dry, and white varieties.
Other port-style fortified wines are produced outside Portugal – in Argentina, Australia, Canada, France, India, Italy, South Africa, Spain, and the United States – but under the European Union Protected Designation of Origin guidelines, only wines from Portugal are allowed to be labelled "port".[2][3]
