noIs Port wine and Black Nail made out of wine?
Port wine 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 "Oporto", "Porto", and "Vinho do Porto" have been recognised as foreign, non-generic names for Port wines originating in Portugal.
Souzão Souzão (Sousão, Vinhão; Spanish: Sousón) is Portuguese wine grape that is used in the production of port wine. While originating in the Minho regions, it is used primarily in Australia, California and South Africa. In Portugal, it is also an authorized planting in the Douro, and Dão-Lafões area (Vinho do Dão). The grape is known for the deep color it produces in a wine as well as its coarse and raisiny taste.
