Port Wine

Port wine, or Vinho do Porto, is one of Portugal’s most iconic wines, known worldwide for its rich flavor and sweet finish.

Produced exclusively in the Douro Valley, this fortified wine has a unique history tied to centuries of trade, aging, and craftsmanship.

Distinctive for its variety of styles—from ruby and tawny to vintage and white—Port wine is both a celebrated sipping wine and a key ingredient in cocktails and desserts.

Some of the grapes most commonly used for its production are Tinta Roriz, Tinta Barroca and Touriga.

A bit of history

Port wine originated in the Douro Valley, where red and white wines were already being produced in the 17th century. Its creation is closely linked to the 1678 conflicts between England and France, which forced the English to look for alternative wine sources. They turned to the Douro and began adding brandy to the wine to stop fermentation, making it more stable for the long journey to England.

This method gave birth to Port wine as we know it today and explains why many historic wine houses have english names. It wasn’t until the creation of the Real Companhia Velha in 1781 that Portuguese producers began to play a major role in the industry.

Where Port Wine is produced

The wine is not produced in Porto but in the Alto Douro Wine Region, declared by Unesco as a World Heritage Site.

When the wine is ready, it is kept and aged in the cellars located just in front of the Ribeira, in Vila Nova de Gaia, District of Porto. And it is from here that it is exported to the rest of the world.

The beautiful Douro Valley

The vineyards, 100 kilometers from Porto, are on very steep terraces, which have been used for the same viticultural purpose for more than two thousand years. The valley has an intricate geography that does not allow to industrialize the process.

That is to say, it is people and not machines that must harvest the grapes, carry them on their shoulders where they are collected in large quantities. Because of this great cultural value, it is an area protected by Unesco as a World Heritage Site.

Once the grapes are harvested, and shortly after fermentation begins, the grape juice is mixed with a neutral wine spirits. This cuts the fermentation of the fruit sugar, so it remains a sweet wine. This type of wine is known as fortified wine, and as such, has a high percentage of alcohol by volume: between 19 and 22 degrees.

Types of Port Wine

Ruby

This is a red wine that ages in huge barrels (20,000 liters) for 8 to 10 years. The little contact with wood (and air) reduces oxidation, thus allowing the wine to retain its initial characteristics for a longer period. Its color is darker than the others and tastes more like red fruits.

Tawny

This wine is made from the same grapes as Ruby, but aged only for 2 to 3 years in the same huge barrels, to be then transferred to smaller barrels. The smaller barrels allow more contact with the wood and air, so the wine oxidizes and ages more rapidly. As a result,the color will be lighter (amber tones) and the tasting notes will be dried fruits, nuts and almonds. The longer they age, the more flavor the tawny wines acquire.

White Por

White port is made in such a way that the must and the skins of the grapes are separated and fermented in large oak barrels of more than 20 thousand liters. Unlike red wine, it is classified by its sweetness, as dry, medium-dry and sweet white port wine. However, because of the way it is produced, these type of wine will never be completely dry.

Rosé Port

Rosé Port is a more recent trend. For its production, the time of exposure of the must and the grape skin is controlled.

Special categories of Port wines

These categories allow to rank the best Port wines.

Reserve

It is produced from selected high quality grapes and can be either white or red. They are usually aged for 7 years in wood and then bottled. They do not age inside the bottle, so it can be kept upright and once opened, it should be consumed within a period of 6 months or less

LBV Port

The name derives from the acronym “Late Bottled Vintage” and are produced from a single exceptional vintage. They age from four to six years inside barrels, and then are bottled. Since they continue to evolve inside the bottle, it is recommended to keep them lying horizontally, but unlike the Vintage category, it is not advisable to wait too long to open them. In a way, the LBVs can be similar to the vintages in flavor, but without the need of long aging years.

Aged Tawnies

These are Tawnies that have been in large oak barrels for more than 10 years. They are one of the most expensive on the market, as the flavor is truly exquisite and unmistakable, experts say.

Colheita

Colheita means harvest in Portuguese. These wines are from a single harvest, which has been classified as special by the Port Wine Institute. On the label we find the respective year of the harvet, which subsequently spent 12 years in small wooden barrels, so they usually have very light colors. The taste of a vintage wine is similar to a 20-year-old Tawny.

Vintage

This is the best designation for a port wine. They have enormous aging potential because they were made from the best grapes chosen for this purpose. First, they are aged for two to three years and then bottled unfiltered, so they still have shavings of the legendary wood from the barrels, which allows them to continue maturing inside the bottle. It is very important to keep the bottles in a horizontal position during the aging process, which never is less than 4 years. In the wineries we can get bottles that have been aging for years and even centuries. They can be opened immediately, but beware, prices are very high.

Bio Port Wine

Not sought after by many, but biodynamic port wine has been making the rounds lately. It's not easy to find, but most port wine brands carry one or two bio versions, and there are some wine bars (and shops) in Porto that dedicate some of their shelf to the category.

When to drink Port Wine

Port wine is served at room temperature, in small liqueur glasses, as an aperitif or as a digestif. In Portugal, it is common to find it as a dessert, accompanying cheeses. It also combines very well with dark chocolate, dried fruits and fruit preserves.

Port Tonic

Port Tonic is rapidly gaining popularity. It is a fresh, light and sweet drink made with white or rosé Port Wine and tonic water. Then just add ice and, if you wish, a slice of lemon or orange and some mint leaves.

Visiting Porto involves visiting some of its wineries and tasting these extraordinary wines, which make a wonderful journey before reaching our palate. More about Porto Wine Cellars

If you want the full experience, you can go to the Douro Valley and visit the quintas (the Portuguese word for estate) where the grapes are grown and the wines produced. A highly recommended excursion.
