Douro Valley Wine: Regions, Grapes and Visiting Guide

The Douro Valley is a wine region in northern Portugal, set along the Douro River, and it is the only place in the world that can make Port. It also makes dry wines under its own name, Douro, and the dry reds are the ones most US drinkers meet first: dark, firm blends of native grapes such as Touriga Nacional. If you like full-bodied reds, or you are planning a trip to Porto and want to see where its wine comes from, this is the region to know.

Figures are from the IVDP, the public institute for Douro and Port wines, and from UNESCO. A DOC (Denominação de Origem Controlada) is Portugal’s top tier of protected wine names: it ties a wine to a defined area and a set of rules on grapes and winemaking.

Where the Douro is and why it matters

The region runs along the river from the Spanish border to about 90 kilometers (56 miles) from the city of Porto, according to Wines of Portugal. The vineyards sit far inland: the Marão and Montemuro mountains shield the valley from the wet Atlantic winds, which is why it is so much drier and hotter than the green Vinho Verde country nearer the coast.

The Douro is old as a wine region and old as a legal idea. UNESCO notes that wine has been made here for about 2,000 years and that Port’s quality has been defined and regulated since 1756. In that year, Wines of Portugal explains, a royal company was set up to mark the region’s boundaries, register its vines and classify its wines, which made the Douro one of the world’s first demarcated wine regions.

Port came first. Wines of Portugal says brandy was added to Douro wine so it would survive the sea voyage and suit the sweeter English taste. Dry, unfortified Douro wines have only gained wide recognition over the last two decades or so.

The three sub-regions

The IVDP divides the Douro into three sub-regions, from west (closest to Porto) to east (the Spanish border):

Sub-region	Total area	Vineyards	Share under vine	What it is like
Baixo Corgo (Lower Corgo)	45,000 ha	13,204 ha	29%	Coolest and rainiest, most fertile, densest planting
Cima Corgo (Upper Corgo)	95,000 ha	20,427 ha	22%	The “heart” of the Douro, home of many top Ports
Douro Superior (Upper Douro)	110,000 ha	10,177 ha	9%	Largest, hottest, driest and most extreme

Areas are the IVDP’s. The descriptions follow Wines of Portugal. The IVDP’s own totals differ by about 100 hectares between two of its tables, so treat the vineyard figures as close approximations.

The east-west contrast is big. The IVDP records annual rainfall of about 1,200 mm (47 inches) at Fontes in the Baixo Corgo and only about 380 mm (15 inches) at Barca d’Alva, near the Spanish border. In our view, that gradient explains a lot of what you see on shelves: lighter, fresher wines tend to come from the west, and many of the most powerful reds from the hot, dry east.

Schist and terraces

The soil

Most of the Douro is schist, a flaky rock that splits into layers. The IVDP describes the topsoil in the vineyards as mostly clay mixed with broken schist, which protects the slopes against water erosion and holds heat. The soils are acidic and low in organic matter and phosphorus.

The terraces

The slopes are so steep that almost every vineyard had to be built by hand. UNESCO and the IVDP describe several generations of terraces:

• Socalcos. The oldest terraces, from before phylloxera (the vine pest that reached the Douro in 1862, according to the IVDP). Narrow, irregular strips held up by dry-stone schist walls, with room for only one or two rows of vines.
• Post-phylloxera terraces. Built in the late 19th and early 20th centuries, when the vineyards were replanted. Wider, with monumental walls and a slight slope to give the vines more sun.
• Mechanized terraces. Introduced at the end of the 1960s and early 1970s: horizontal terraces with one or two rows of vines, built so machines can work them. The IVDP notes they need large plots, so they don’t suit smallholdings.
• Vinha ao alto. Vines planted in vertical rows straight up the hill, without terraces. The IVDP says this suits small plots on slopes of up to about 40%.

Note: The terraces are the reason the Douro is on the UNESCO list. The World Heritage site covers about 24,600 hectares of terraced vineyards along the Douro and its tributaries (the Varosa, Corgo, Távora, Torto and Pinhão rivers), with a buffer zone of about 225,400 hectares.

UNESCO’s Alto Douro Wine Region

UNESCO inscribed the Alto Douro Wine Region on the World Heritage List in 2001 as a cultural landscape. It met three of UNESCO’s criteria: nearly 2,000 years of winegrowing that shaped the land, a landscape that shows the full range of winemaking activity (terraces, quintas or wine estates, villages, chapels and roads), and an outstanding example of a traditional European wine region. UNESCO also points out the orange groves along the lower riverbanks and the white-walled villages halfway up the slopes.

The grapes

The Douro’s wines are almost always blends. The IVDP names these as the key varieties for Douro wines:

Color	Grape	Notes
Red	Touriga Nacional	One of the five red grapes Wines of Portugal highlights for Port
Red	Touriga Franca	Also written Touriga Francesa; another of the five Port grapes
Red	Tinta Roriz	Spain’s Tempranillo; the IVDP also lists it as Aragonez
Red	Tinta Barroca	One of the five Port grapes
Red	Tinto Cão	One of the five Port grapes
White	Malvasia Fina, Viosinho, Gouveio, Rabigato	The main whites for dry Douro white
White	Moscatel Galego	The only grape for Moscatel do Douro

Those five reds are also the varieties Wines of Portugal singles out for Port. Old vineyards often mix dozens of varieties in the same plot, so many old-vine wines are “field blends” rather than recipes.

Port and Douro DOC: the two names

According to the IVDP, there are two designations of origin in the Douro Demarcated Region: Port and Douro. They share the same vineyards, but the wines are very different.

• Port (Porto) is the region’s fortified wine, strong and usually sweet.
• Douro DOC covers the region’s unfortified wines: dry reds, whites and rosés, plus smaller categories. The IVDP lists Moscatel do Douro (a fortified white made only from Moscatel Galego), Espumante do Douro (sparkling wine) and Colheita Tardia (late-harvest wine from grapes affected by noble rot).

What dry Douro wines taste like

The IVDP splits Douro wines into styles to drink young and styles made for aging:

Style	What the IVDP describes	Serve at
Young red	Ruby color, red-fruit aromas, well balanced	13–15°C (55–59°F)
Aged red	Deeper color, black fruit, chocolate and wood notes, firm and persistent tannins, velvety at its peak	16–18°C (61–64°F)
Young white	Pale, fruity, refreshing and citrusy	8–10°C (46–50°F)
Aged white	Often fermented or aged in wood; golden, toasty, full-bodied	About 12°C (54°F)
Rosé	Young and fruity, raspberry and cherry; drink within 1–2 years	10–12°C (50–54°F)

Tannin is the drying, grippy feel from grape skins; the aged reds have plenty of it. We’d pour a young Douro red where you might pour a Côtes du Rhône, and save the aged ones for grilled steak, lamb or a hearty stew.

How to read a Douro label

• “Douro” with “Denominação de Origem Controlada” (or DOC/DOP). A dry or unfortified wine from the demarcated region, certified by the IVDP.
• “Porto” or “Port”. Fortified Port wine, with its style usually printed nearby.
• Tinto, branco, rosé. Red, white, rosé.
• Reserva and Grande Reserva. The IVDP notes these terms appear on many of the reds and whites made for aging. They are official Portuguese designations; our guide to Portuguese wine explains what they mean.
• Quinta. A wine estate. Many single-estate Douro wines carry the quinta’s name.
• Moscatel do Douro, Espumante, Colheita Tardia. The specialty categories above.

In our view, the sub-region rarely appears on the front label, so the back label or the producer’s website is the best place to find out whether a wine comes from the cooler west or the hot Douro Superior.

Visiting the Douro Valley

The Douro is easy to reach from Porto, and the IVDP’s wine route lists many estates that welcome visitors. These basics will help you plan; check opening times, bookings and fares directly with each place before you go.

Start in Porto and Vila Nova de Gaia. Port takes its name from the harbor between Porto and Vila Nova de Gaia. Wines of Portugal explains that the wine came down the river in rabelo boats and aged in Gaia’s warehouses, where the temperature changes little through the year. Those Port lodges, many dating back to the 19th century according to the IVDP, offer guided tours with a Port tasting, so they are a natural first stop before heading upriver.

Take the train. The national railway CP describes the Douro Line as running about 172 kilometers (107 miles) from Porto to Pocinho, with 37 stations and halts, and much of the route alongside the river with views of the vineyard terraces. The line reached Régua in 1879 and Pinhão in 1880; CP calls Pinhão’s station one of the most beautiful in Portugal. Toward the end, between Ferradosa and Pocinho, the track crosses from the right bank of the river to the left. In our view, the train is the easiest way to see the valley if you don’t want to drive mountain roads after a tasting.

Stay at or visit a quinta. The IVDP’s Port and Douro Wines Route links wineries and estates that welcome visitors. It lists tastings and local food at quintas, hiking, mountain biking and guided tours through vineyards and historic wine villages, and longer trips that can combine the train with a visit to the prehistoric rock engravings at Vila Nova de Foz Côa.

Plan by sub-region. Régua and Pinhão are the best-known stops on the line. Past them, the Douro Superior toward the Spanish border is the largest, hottest and most extreme part of the region, and the train runs all the way to Pocinho.

Tip: Never plan to drive between tastings. Book a driver or a tour, or use the train, and pace yourself: a day of tastings adds up.
