Port is a strong, usually red, fortified wine. It originates in northern Portugal, from the city of Porto in the Douro region. While true port is always from Portugal, in recent years, port has come to be used as a generic term for this style of fortified wine. As a result, many Portuguese producers have begun to differentiate their product by labeling it Porto.

Port is made by adding a grape brandy to the wine as it is fermenting. This stops the wine from fermenting any further, leaving it substantially more alcoholic – and therefore with a higher sugar content, since less of the sugar is able to finish converting into alcohol. This practice has been around for hundreds of years, since brandy was historically added to wines from northern Portugal to help them remain preserved during their trip to England.

Nearly all port is red, but there is a special variety of white port that has little popularity outside of Portugal. This white port is made by using very pale grapes. Some cheaper tawny ports fake the subtlety of age by adding white port to a younger tawny port.

Wood ports are the most common type of port. A ruby port is a young port, having aged in the cask but not in the bottle. Ruby ports are full of energy and don’t have much subtlety to them. A tawny port is a wood port that has been aged in the cask for an extended period of time – 10 to 40 years, usually – and so has taken on a lighter, “tawny” color.

A vintage port is aged for two years in the cask, and then left for a long period of time to age in the bottle. Vintage ports are not made every year – about one in three years is deemed good enough for vintage – but are far superior to wood ports. Vintage port often has sediment in the bottom from aging, and so should be decanted before drinking. A good vintage port should not be ready to be drunk for at least 10 to 20 years, and can continue to age for far longer than that. Because of how long it takes to age, many parents buy a good bottle of vintage port when a child is born, to be bestowed upon the child on his or her 18th or 21st birthday – or whatever the legal age of drinking may be in their country.

Late bottled vintage port, or LBV port is a lesser variety of vintage port. These ports are bottled between four and six years after production, and can be drunk upon release, requiring no extended aging like the vintage ports. They range from rather low quality to those that come close to meeting the quality of the true vintage varieties. A vintage character port is a special type of LBV that blends vintages together from the best years.

Port is a perennial favorite drink throughout the world, particularly in England and France. Some people enjoy it as an aperitif, and others prefer it as a dessert wine, but all those who enjoy it hold it in a special place in their hearts.
