Douro Valley

IVV traces the Douro's link to wine back to the Roman occupation, when vines were already grown in the valleys of the Alto Douro, and describes the region as the oldest demarcated and regulated wine region in the world, created in 1756 by the Marquês de Pombal. Taylor's own history notes that in 1744 Bartholomew Bearsley became the first British wine shipper to buy a property in the Douro, and that in the 1761 classification Taylor's Quinta do Junco was awarded full feitoria status, identifying its wines as entitled to a higher price and to export to the English market. According to IVDP, the Cachão de Valeira canyon, a granite outcrop that blocked navigation, once separated the Alto Douro from the Douro Superior; after it was removed during the reign of Queen Dona Maria II, viticulture spread eastwards. Phylloxera first appeared in the region in 1862, after which the small old terraces were abandoned as mortórios and new, wider terraces were built. The Port Wine Institute was created in 1933 and is today the IVDP. Barca Velha, a dry red, was first harvested in 1952 at the Quinta do Vale Meão estate, chosen by Casa Ferreirinha winemaker Fernando Nicolau de Almeida.

• 1756: IVV dates the creation of the demarcated region to 1756 under the Marquês de Pombal
• 1761: in the classification of that year, Taylor's Quinta do Junco received full feitoria status, the rank for wines entitled to export to the English market
• 1862: phylloxera first appeared in the region; the abandoned pre-phylloxera terraces are known as mortórios
• 1952: Barca Velha was first harvested at Quinta do Vale Meão, chosen by Casa Ferreirinha winemaker Fernando Nicolau de Almeida for a top quality dry red

IVDP locates the Douro Demarcated Region in northeast Portugal, within the Douro River basin and surrounded by craggy mountains, over a total area of approximately 250,000 hectares divided into three sub-regions. Baixo Corgo (Lower Corgo) runs from Barqueiros on the north bank and Barrô on the south bank to the point where the Corgo River and the Ribeiro de Temilobos flow into the Douro at Régua. Cima Corgo (Upper Corgo) extends upstream from there to the Cachão de Valeira, and Douro Superior (Upper Douro) runs from the Cachão de Valeira east to the Spanish border. In IVDP's 2020 figures the region had 43,708 ha under vines: 13,204 ha in Baixo Corgo, 20,427 ha in Cima Corgo and 10,077 ha in Douro Superior. The Marão and Montemuro mountains act as barriers against the humid west winds from the Atlantic, giving very cold winters and hot, dry summers. Annual rainfall ranges from 1,200 mm at Fontes to 380 mm at Barca d'Alva and decreases from Barqueiros toward the Spanish border, while average annual temperatures range from 11.8 to 16.5°C. Most of the region is schistose with some granite around the edges; the topsoil contains little organic matter (1.5%) and is predominantly acid. Writing in Decanter, Margaret Rand describes the Cima Corgo as the source of most top Port and the Baixo Corgo as the source of most basic Port, and Quinta do Vale Meão in the Douro Superior as much hotter and drier than the Cima Corgo.

• Three sub-regions: Baixo Corgo (13,204 ha of vines), Cima Corgo (20,427 ha) and Douro Superior (10,077 ha), per IVDP's 2020 figures
• The Marão and Montemuro mountains block humid Atlantic west winds; IVDP describes very cold winters and hot, dry summers
• Soils are mostly schistose with some granite around the edges; the Douro DOC specification calls for vineyards on predominantly schist soils, not excluding patches of granite
• Terraces: after phylloxera, wider terraces allowed about 6,000 vines per hectare; horizontal terraces with earthen walls (patamares) arrived in the late 1960s and early 1970s, and vertical rows up the slope (vinha ao alto) suit plots with slopes of up to 40%
• Altitude: António Magalhães, head of viticulture at The Fladgate Partnership, told Decanter that every 100m of altitude means a 0.5ºC difference in temperature

IVDP names Tinta Amarela, Tinta Barroca, Tinta Roriz, Touriga Francesa, Touriga Nacional and Tinto Cão as the most noteworthy red varieties, with Malvasia Fina, Viosinho, Donzelinho and Gouveio the predominant whites. Douro red wines are made from native vines such as Touriga Nacional, Touriga Franca, Tinta Roriz (Aragonez), Tinta Barroca and Tinto Cão; most are blends, though single-variety wines are also made. Dry whites blend varieties such as Malvasia Fina, Viosinho, Gouveio and Rabigato. Port is made by stopping the fermentation of the must with grape brandy (aguardente), a step IVDP calls benefício, and usually carries between 19 and 22% alcohol. IVDP divides Port into the Ruby style (Ruby, Reserve, Late Bottled Vintage and Vintage) and the Tawny style (Tawny, Tawny Reserve, Tawny with an Indication of Age of 10, 20, 30 and 40 years, and Colheita), alongside White and Rosé Port. Vintage Port comes from a single year's harvest and is bottled two to three years after the vintage; LBV is a Ruby Port from a single year bottled after four to six years in wood; Colheita is a single-vintage Tawny aged at least seven years in cask. The region also produces Moscatel do Douro from Moscatel Galego grapes, Douro sparkling wine and late-harvest Colheita Tardia.

• Most noteworthy reds per IVDP: Tinta Amarela, Tinta Barroca, Tinta Roriz, Touriga Francesa, Touriga Nacional and Tinto Cão; predominant whites: Malvasia Fina, Viosinho, Donzelinho and Gouveio
• Port: fermentation is stopped by adding grape brandy; alcohol usually between 19 and 22% vol., with a 16.5% minimum for Light Dry White Port
• Tawny with an Indication of Age (10, 20, 30 and 40 years) blends wines from several years; Colheita is a single-year Tawny aged at least seven years in cask
• Vintage Port: single harvest, bottled two to three years after the vintage; Single Quinta Vintage Port comes from a single harvest and a single estate

Taylor's was founded in 1692 by Job Bearsley and has remained independent; its Vintage Ports are blended from its own quintas Vargellas, Terra Feita and Junco, and it launched its Late Bottled Vintage in 1970 with the 1965 vintage. Graham's was founded in 1820 by brothers William and John Graham and acquired Quinta dos Malvedos in 1890; in 1970 the grandsons of Andrew James Symington acquired the company from the Graham family. Casa Ferreirinha, whose A.A. Ferreira roots trace back to 1751, has been owned by Sogrape since 1987; Quinta da Leda was bought in 1979, and Sogrape reports that the majority of the Barca Velha 2015 blend came from its vineyards. Quinta do Vale Meão was bought at auction in 1877 for Antónia Adelaide Ferreira (1811-1896), became the sole property of Francisco Javier de Olazabal and his children in 1994, and launched its own wines with the 1999 harvest. Quinta do Crasto reports 40 hectares of old vines divided among 42 vineyard lots.

• Taylor's (founded 1692): Vintage Ports from Quinta de Vargellas, Quinta de Terra Feita and Quinta do Junco; Late Bottled Vintage launched in 1970 with the 1965 vintage
• Graham's (founded 1820): Quinta dos Malvedos acquired in 1890; owned by the Symington family since 1970
• Casa Ferreirinha (Sogrape since 1987): Barca Velha first made in 1952; Quinta da Leda bought in 1979
• Quinta do Vale Meão: bought at auction in 1877 for Antónia Adelaide Ferreira; first own-label wines, Quinta do Vale Meão and Meandro do Vale Meão, from the 1999 harvest

The IVDP was created in 1933 as the Port Wine Institute and is a public body overseen by the Minister of Agriculture; it controls the quality and quantity of Port and Douro wines and protects the Douro and Port designations of origin and the Douro geographic indication. Per IVV, the Douro holds two designations of origin on one territory, DOP Porto and DOP Douro, and the IGP Duriense covers the same area. The Douro specification lists Denominação de Origem Controlada (D.O.C.) among its traditional terms. Of the land under vines, only 26,000 ha are authorised for Port; vineyards are scored on soil, climatic and agricultural parameters, including location, altitude, slope, bedrock, exposure, shelter, yield, planting density, training system and age, and classed from A (over 1,200 points) to F (201 to 400 points). Vines must be at least five years old before they can produce Port, and the benefício coefficient attributed to a vineyard is calculated from its registered characteristics. For DOP Douro, the specification sets a minimum acquired alcohol of 10.5% vol. for white and rosé and 11.0% vol. for red wines, and maximum yields of 55 hl/ha for red and rosé and 65 hl/ha for white. For Port, the must needs an average natural potential alcohol of at least 11% vol., and the finished wine an acquired alcohol between 19% and 22% vol., except Light Dry White Port at a minimum of 16.5% vol.

• IVDP vineyard classes run from A (over 1,200 points) to F (201 to 400 points); only 26,000 ha are authorised for Port
• Port: acquired alcohol 19% to 22% vol. (Light Dry White Port minimum 16.5% vol.); sweetness terms run from Extra-Seco (17.5 to 40 g/L of sugars) to Muito doce or Lágrima (over 130 g/L)
• DOP Douro: minimum acquired alcohol 10.5% vol. for white and rosé, 11.0% vol. for red; maximum yield 55 hl/ha for red and rosé, 65 hl/ha for white
• The Port designation of origin covers the same geographic area as the Douro designation of origin

Writing for Decanter, André Ribeirinho notes that Peso da Régua is a little over an hour's drive from Porto, and that the 2.5-hour train from Porto's São Bento station is the most scenic way to arrive. He lists Quinta do Bomfim, a Symington property making Dow's, with a visitor centre; Fonseca's Quinta do Panascal, one of the first visitor centres in the Douro and open throughout the year; Quinta do Noval, with a manor open for tastings; and the Niepoort family's Quinta de Nápoles. IVDP places the harvest between the end of August and mid-October, and describes a traditional technique in which the grapes are trod in large stone tanks. IVDP suggests young Douro reds with simple meat dishes or salt cod, and reds made for ageing, when drunk young, with red meat dishes such as sirloin steak, calling them perfect for traditional Portuguese dishes such as veal cutlets or roast kid.

• Peso da Régua is a little over an hour's drive from Porto; the train from São Bento station takes about 2.5 hours, per Decanter
• Quinta do Bomfim (Symington, Dow's) and Quinta do Panascal (Fonseca) run visitor centres, per Decanter
• Harvest begins between the end of August and mid-October, per IVDP
• Decanter's guide calls the beginning of autumn the ideal time to visit, for the mild weather and the colours of the vineyards
