Port wine is a fortified wine and naturally produced exclusively from grapes from the Douro Wine Region, in northern Portugal about 100 miles east of Porto. Ruler and Pinion are the main centers of production, but some of the best vineyards lie in the area farther east. the port wine has 16 brands available. Although produced with grapes from the Douro and stored in cellars in Vila Nova de Gaia, this alcoholic beverage known as "port wine" from the second half of the seventeenth century to be exported around the world from this city. Vila Nova de Gaia is the place with the highest concentration of alcohol per square meter in the world. The "discovery" of Port wine is controversial. One version, championed by producers of England, says that the origin date of the seventeenth century, when British merchants added brandy to the wine from the Douro region to prevent it sour. But the process that characterizes the attainment of precious nectar was already well known prior to commencement of trading with the English. In the Age of Discoveries wine was stored in this way to save a maximum of time during journeys. The fundamental difference lies in the area of production and the varieties used today protected. The company was the first to Croft export port, followed by other English and Scottish companies. What makes the port wine different from other wines, besides the unique climate, is the fact that the fermentation of wine is not complete, it was stopped at an early stage (two or three days after the initiation), by addition of a brandy neutral grape spirit (about 77 degrees of alcohol). Thus Port wine is a naturally sweet wine (since the natural sugar of the grapes does not become completely alcohol) and stronger than other wines (between 19 and 22 alcohol).
Fundamentally consider three types of port wines: White, Ruby and Tawny.
Port wine that ages up to three years is considered standard. All other wines that stay longer aging in wood belonging to special categories, either because the grapes that originated are better quality, either because they were produced in an exceptionally good year in terms of weather. Thus, among the special categories, it is common to find the reserve, the LBV, the aged Tawny and Vintage, and, less regularly, the Harvest.
