Douro is a Portuguese wine region centered on the Douro River in the Trás-os-Montes e Alto Douro region. It is sometimes referred to as the Alto Douro (upper Douro), as it is located some distance upstream from Porto, sheltered by mountain ranges from coastal influence. The region has Portugal's highest wine classification as a Denominação de Origem Controlada (DOC). While the region is associated primarily with Port wine production, the Douro produces just as much table wine (non-fortified wines) as it does fortified wine. The non-fortified wines are typically referred to as "Douro wines".

The style of wines produced in the Douro range from light, Bordeaux style claret to rich Burgundian style wines aged in new oak.

There is archaeological evidence for winemaking in the region dating from the end of the Western Roman Empire, during the 3rd and 4th centuries AD, although grape seeds have also been found at older archaeological sites. In Medieval times from the mid-12th century, Cistercians had an important influence on winemaking in the region, through their three monasteries Salzedas, São João de Tarouca and São Pedro das Águias.

Carlos Alonso (born Tunuyán Mendoza, Argentina, 4 February 1929), is a contemporary Argentine painter, draftsman and printmaker. Though he was a Social realist in his early career, he is best known as a New realist.Beef is a common element in his work.

Born in Tunuyán, where he lived until age seven, he later moved with his family to Mendoza. At the age of fourteen, he entered the Academia Nacional de Bellas Artes where he studied under Sergio Sergi in drawing and engraving, Lorenzo Dominguez in sculpture, and Bernareggi Francisco and Ramón Gomez Cornet in painting. At the National University of Cuyo, he studied with Lino Enea Spilimbergo.

Alonso received his first award in 1947. In 1951, he won first prize at the Salon of Painting in San Rafael, the North Hall in Santiago del Estero, and drawing at the Salon del Norte Tucumán. In 1953, Alonso exhibited at the Gallery Viau of Buenos Aires, then traveled to Europe where he exhibited in Paris and Madrid. In 1957, he won the competition held by Emecé Editores to illustrate the second part of Don Quixote, and Martín Fierro in 1959. In 1961, he won the Premio Chantal del Salón de Acuarelistas y Grabadores of Buenos Aires. In the same year, while visiting London, he discovered acrylic painting techniques. His Don Quixote pictures were published on postcards in the Soviet Union in 1963.
