The Port Wine Museum (PT: Museu do Vinho do Porto) is a museum located in Porto, Portugal.
 It was founded in 2004, and it is focused on the history of Port wine and its relevance to the city and the country.
 The museum is located in an 18th-century warehouse, next to Douro River.
The Douro Wine Company (also known as the General Company of Agriculture of the Wines of the Upper Douro and in Portuguese Companhia Geral da Agricultura e Vinhos do Alto Douro) was a government oversight organization established by the Portuguese Prime Minister Sebastião José de Carvalho e Melo, Marquis of Pombal to regulate the trade and production of Port wine.
 Established in 1756, one of the first official duties of the company was the delineation of the boundaries of the Douro wine region.
 This act essentially made the Douro the world's first regional appellation.
 While the boundaries of the Chianti and Tokaji wine regions were outlined in 1716 and 1737, respectively, neither of these regions were "technically" appellations in the sense of being subjected to continued government control and regulations.
 Under their charter, Pombal invested an immense amount of control in the Douro Wine Company to regulate all exports of Port, set production quantities limits, fix maximum and minimum prices for grapes and to serve as sole arbitrator in any disputes between vine growers and Port shippers.
 In 1761, the company was further granted a monopoly on the sale of brandy which was used in the fortification process of Port winemaking.
 The Douro Wine Company continued to operate to 1833 (and was briefly revived from 1843 and 1853).
 Today, many of it functions have been deregulated with the Instituto dos Vinhos do Douro e do Porto or (Port and Douro Wines Institute) being the official regulating body of Port wine and Douro table wine production.
According to the Method of Punctuation of the Plots of Land of Vineyards of the Region of Douro (decree nº 413/2001), there were 30 recommended and 82 permitted grape varieties in Port wine production.
 The quality and characteristics of each grape varies with the classification of grape varieties making a distinction between "Very Good", "Good", "Average", "Mediocre" and "Bad" quality grapes.
 But this classification is actually in revaluation based on the technical and scientific data of the CEVD (Center of Wine Studies of Douro).
 The six most widely used grapes for red Port wine are Touriga Franca, Tinta Roriz, Tinta Barroca, Touriga Nacional, Tinto Cão and Tinta Amarela.
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.
The Bananarita is a variation of a margarita with a banana liquor, but served in a cocktail glass (on the rocks).
Schilcher is a wine produced solely in the Austrian region of Western Styria ("Weststeiermark") and Southern Burgenland (Südburgenland), in the districts of Deutschlandsberg and Voitsberg, sharing a border with Slovenia and Carinthia to the south and west.
 The wine growing area is the smallest in Europe.
 The Schilcher wine itself is a distinct rosé made from the indigenous Blauer Wildbacher grape.
 The colour ranges from a light onion tinge to a deep ruby.
 The grape was once a wild variety which was said to contain alcohol compounds which, in turn, allegedly would induce wild inebriation, hence its colloquial name "Rabiatperle" - rabid pearl.
 The name Schilcher originates from the Middle High German word "schillern" meaning to radiate with colour.
Symington Family Estates is a wine company and Port wine house in Portugal, which owns and operates several vineyards and wineries and owns several brands of Port, Madeira wine and Douro DOC wines, including some of the oldest and most well-known Port and Madeira brands.
 With their extensive vineyard holdings and many Port brands, the Symingtons are often described as being a "Port empire".
Vintage, in winemaking, is the process of picking grapes and creating the finished product (see Harvest (wine)).
 A vintage wine is one made from grapes that were all, or primarily, grown and harvested in a single specified year.
 In certain wines, it can denote quality, as in Port wine, where Port houses make and declare vintage Port in their best years.
 From this tradition, a common, though incorrect, usage applies the term to any wine that is perceived to be particularly old or of a particularly high quality.
Akadama (赤玉 ) , originally Akadama port wine is a Japanese sweet red wine created in 1907 by Shinjiro Torii, the founder of Suntory.
 Akadama sweet wine remains popular amongst all generations and is still found in stores across Japan today.
 Just like Sherry and Madeira wine, Akadama port wine is a Fortified wine; it is sweeter than the general wines.
Port wine cheese is an orange- and red-colored cheese or cheese spread that is heavily dosed with alcoholic port wine as it is made.
 It is typically used as a cheese spread on foods such as crackers.
 It can be rolled into a cylindrical shape or into a ball, and is sometimes covered in crushed walnuts.
 Port wine cheese is a mass-produced product in the United States, and several brands are purveyed to American consumers.
