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.
Noble rot Noble rot (French: "pourriture noble" ; German: "Edelfäule" ; Italian: "Muffa nobile" ; Hungarian: "Aszúsodás" ) is the beneficial form of a grey fungus, "Botrytis cinerea", affecting wine grapes. Infestation by "Botrytis" requires moist conditions. If the weather stays wet, the damaging form, "grey rot," can destroy crops of grapes. Grapes typically become infected with "Botrytis" when they are ripe. If they are then exposed to drier conditions and become partially raisined this form of infection is known as noble rot. Grapes when picked at a certain point during infestation can produce particularly fine and concentrated sweet wine. Wines produced by this method are known as botrytized wines.
