A strictly limited production area is set aside for the cultivation of port wine along the Duero river. In the city of Porto you can see the ships loaded with port wine passing by daily.
Portugal, Porto and especially the Douro Valley are well known for their predominantly red port wine. Rarer is the white form of the sweet wine. The famous port wine from the Portuguese coastal city of Porto bears the name. The history of winegrowing in the Douro Valley goes back to the 13th century. The name "Porto" was first documented around the year 1680, when priests created the first edible bottling. During the fermentation a neutral alcohol was added to the wine. The fermentation was thus stopped and a certain amount of residual sugar remained. In the meantime, more than 80 varieties of grape have been approved for port wine production. It is only after two years that the wine is tasted for the first time and a decision is made on the further maturing process. A distinction is made between different red port wine styles such as Ruby (bottle-aged) or Tawny style (cask-aged). For white port wine, the categories very sweet, sweet, semi-dry, dry and very dry are differentiated.
Madeira is a protected designation for a liqueur wine that comes from the island of Madeira. The wine is enriched with brandy and at the end of the production process contains 17 to 22% alcohol by volume.
An interesting side-fact is also that Portugal produces all wine corks itself and is the number 1 in the world cork production. On delicando you find Mateus Rosé and also Fabelhaft Duoro.
