Tawny Port (Basic; Blended; Amber Color from Wood Aging)

Portuguese wine exports entered a new phase of expansion in 1703, when the Methuen Treaty set out an agreement to regulate trade between Portugal and England. On 10 September 1756, by royal charter, the Companhia Geral da Agricultura das Vinhas do Alto Douro was created to discipline the production and trade of the region's wines and to establish the demarcation of the region, the birth of one of the world's first demarcated regions; the Marquis of Pombal exerted a strong influence on the winegrowing sector. As Port exports increased, brandy began to be added so the wine resisted the sea journey, and stopping fermentation with brandy made the wine sweeter. The name "do Porto" comes from the port between the city of Porto and Vila Nova de Gaia, where the wine was stored and sold: it came down the Douro in rabelo boats to age in the warehouses of Vila Nova de Gaia, an area with little temperature variation during the year. The IVDP, today's control and certification body, was created in 1933 as the Port Wine Institute.

• 1703: the Methuen Treaty regulated trade between Portugal and England, and Portuguese wine exports entered a new phase of expansion
• 10 September 1756: the Companhia Geral da Agricultura das Vinhas do Alto Douro was created by royal charter; its competencies were to limit the region, register the vines, classify the wines by quality and establish certain winemaking practices
• 1933: the Port and Douro Wines Institute (IVDP) was created as the Port Wine Institute; it upholds the control of the quality and quantity of Port and Douro wines
• July 2021: the IVDP announced a new 50-year-old category for both tawny and white Port, adding to the existing 10, 20, 30 and 40 year categories

Port is produced in the Demarcated Region of the Douro in northeast Portugal, which spreads over a total area of approximately 250,000 hectares, divided into three sub-regions: the Lower Corgo (Baixo Corgo), the Upper Corgo (Cima Corgo) and the Upper Douro (Douro Superior). Baixo Corgo, under the direct influence of the Serra do Marão, is the coolest and rainiest sub-region, the most fertile and with the highest density of vines; Cima Corgo is the heart of Douro, where many of the wines from the upper end of the Port segment are born; and Douro Superior is the largest sub-region and the hottest and driest. In 2020, plots covered a total area of 13,204 ha in the Lower Corgo, 20,427 ha in the Upper Corgo and 10,077 ha in the Upper Douro, 43,708 ha in all. The Marão and Montemuro mountains protect the region from the humid west winds off the Atlantic, giving very cold winters and hot, dry summers, and most of the region's soil, particularly along the Douro and its tributaries, is schistose with some granite around the edges. A tawny made in the hot Douro Valley undergoes a different and more rapid maturation than a tawny aged in the cooler, more humid conditions of Vila Nova de Gaia.

• Sub-regions: Baixo Corgo is the coolest and rainiest, Cima Corgo is the heart of Douro, and Douro Superior is the largest, hottest and driest
• Rainfall: annual rainfall ranges from 1,200 mm at Fontes to 380 mm at Barca d'Alva, decreasing from Barqueiros toward the Spanish border
• Soils: the topsoil is mostly clay mixed with particles of broken schistous rock, which lets water seep down to the roots of the vines and holds the heat from the sun
• Vila Nova de Gaia: Port historically aged in its warehouses because the area has little temperature variation during the year

Wines of Portugal singles out five red varieties for their excellence in producing Port Wine: Tinta Barroca, Tinta Roriz, Tinto Cão, Touriga Franca and Touriga Nacional. The IVDP's list of the region's most noteworthy red varieties is Tinta Amarela, Tinta Barroca, Tinta Roriz, Touriga Francesa, Touriga Nacional and Tinto Cão, and the varieties that may be planted are regulated by a Decree-Law. For aged tawny blends, Port consultant Jim Reader told Decanter: "There is likely to be less Touriga Nacional and Touriga Franca in the blend, although these varieties continue to be important, and a greater use of varieties such as Tinta Barroca, Tinto Cão and Tinta Roriz." Carlos Alves, winemaker for the Sogevinus group, told Decanter that balance comes from "using grapes from different altitudes and different stages of maturation."

• Wines of Portugal's five standout Port reds: Tinta Barroca, Tinta Roriz, Tinto Cão, Touriga Franca and Touriga Nacional
• The IVDP's list of the most noteworthy red varieties also includes Tinta Amarela; its predominant white varieties are Malvasia Fina, Viosinho, Donzelinho and Gouveio
• Tawny blends: Jim Reader expects less Touriga Nacional and Touriga Franca and a greater use of Tinta Barroca, Tinto Cão and Tinta Roriz
• Vines must be at least 5 years old before they can be considered apt to produce Port Wine

The Douro harvest begins each year between the end of August and mid-October. Red Port is made either traditionally, with the grapes trodden in large stone tanks (lagares), or in wineries fitted with modern technology. At a certain moment during fermentation the wine is drawn off from the skins, stalks and pips into another tank, where grape spirit (aguardente vínica, the addition called benefício) is added to halt fermentation, most often in a proportion of one part spirit to four parts must-wine, so the final wine keeps some residual sweetness and between 19% and 22% alcohol. The wines rest until the end of winter; in spring a first selection and blending is made, and the winemaker decides whether each wine will age in the Douro or downriver in the Vila Nova de Gaia bonded lodges. Tawny-style Ports age in wood, in lodge pipes of 600 to 640 liters where the wine undergoes gradual, controlled oxidation and esterification as the color fades and ethyl esters and acetals develop, a process influenced by storage temperature and evaporation rate. Tasting and blending are continuous: a final lote may be made up of anything between 10 and 50 component wines, with younger, fresher, fruit-driven Ports balancing older, mature styles, and it must be submitted to the IVDP tasting panel for approval.

• Fortification: grape spirit halts fermentation, most often at one part spirit to four parts must-wine; the Port specification requires the stopped fermentation to leave a minimum of 17.5 g/L of sugars
• Vessels: the tawny style is a blend of wines of varying maturity aged in wood (pipas, tonéis or balseiros)
• Oxidative change: in lodge pipes the color fades from deep, opaque ruby to orange-amber-tawny as ethyl esters and acetals develop
• Blending: a final tawny lote may combine between 10 and 50 component wines, younger and fruit-driven wines balancing older, mature ones
• Grape spirit: under the Port specification, the spirit has a strength of 77.0 ± 0.5% vol. at 20°C, and the amount added to raise the alcohol and stop fermentation, depending on the sweetness wanted, is set each year in the harvest communiqué (comunicado de vindima)

Symington Family Estates' Ports are Graham's, Dow's, Warre's and Cockburn's. Graham's was founded by brothers William and John Graham in 1820, built its Lodge in Gaia in 1890, and was acquired from the Graham family in 1970 by the grandsons of Andrew James Symington. The Graham's 1890 Lodge in Vila Nova de Gaia contains 15,000 seasoned oak casks, some over a hundred years old, and Graham's has launched a range of Single Harvest Tawny Ports dating back to 1952. The Fladgate Partnership's original company is Taylor's Port, founded in 1692; in 2001 it acquired Croft Port, founded in 1588, and its other Port brand is Fonseca. Kopke dates back to 1638, and Decanter's Richard Mayson calls it the oldest of all the Port wine houses; it was the first Port house to launch wines in the 50-year-old category. The Sogevinus group includes tawny specialists Kopke, Cálem and Burmester.

Port is a protected designation of origin: the statute of the Douro Demarcated Region recognizes the DOP Porto, including the designations vinho do Porto, Port wine and Port. The IVDP, a public body overseen by the Minister of Agriculture, controls the quality and quantity of Port and Douro wines and protects their designations of origin, and to obtain approval for a given Port category, samples of the wine must be delivered to the IVDP. A Tawny Reserve is aged in oak with a medium amber color and must have aged in wood for a minimum of 6 years. Indication of Age Ports are blends of wines from several years that have aged in wood, combined to achieve complementary organoleptic characteristics and recognized by the IVDP; the permitted indications are 10, 20, 30, 40 and 50 years, wines with 10 or 20 years may use Old, wines with 30, 40 or 50 years may use Very Old, and wines over 80 years may use Very Very Old, VVO or W without an indication of age. The IVDP's special categories page lists the indications as 10, 20, 30, 40, 50 and 80 years plus VVO, and sets the minimum grades required at the Câmara de Provadores. Like the other age categories, 50-year-old is an indication of age rather than a specific age.

• DOP Porto: the Douro statute recognizes the designation of origin Porto, including vinho do Porto, Port wine and Port
• Tawny Reserve: aged in wood for a minimum of 6 years; minimum grade at the Câmara de Provadores of 7 out of 10
• Indication of Age: 10, 20, 30, 40 and 50 years in the IVDP's definitions, with 80 years added on its special categories page; VVO is used for wines with more than 80 years in wood, without an age on the label
• Colheita: a single harvest aged a minimum of 7 years in wood, counted from 1 September of the second year after the harvest, with the harvest year and bottling year on the label
• Colheita style: Colheitas are wines of a single year that usually resemble a Tawny with an Indication of Age of the same ageing time
