The DO area for red, rosé and white wines is located between the two cities of Toledo and Madrid in the Spanish region of La Mancha in the province of Toledo and is named after the city of the same name. The wines have been known since the 16th century. The vineyards, which are quite flat except for the foothills of the Sierra de San Vicente in the northeast, cover 13,000 hectares of vineyards on gently sloping hillsides at 400 to 600 metres above sea level, and in some of the more than 50 municipalities up to 800 metres. The sandy clay soils are poor in organic nutrients. The area borders the two DO areas of Cebreros(Castile-León) and Vinos de Madris(Madrid). Together, these three DO areas form the Sierra de Gredos wine-growing area, which slopes down to the north towards the Alberche Valley and to the south towards the Tiétar Valley. The continental climate is characterised by long hot summers with considerable temperature variations and cold winters. The red and rosé wines are made from Garnacha Tinta (80% of the area), Cencibel (Tempranillo), Petit Verdot, Cabernet Sauvignon and Syrah. The white wines are produced from Albillo Real, Macabeo, Verdejo, Chardonnay, Moscatel de Grano Menudo (Muscat Blanc) and Sauvignon Blanc.
