Ribera Del Duero - Geography

Geography

The Ribera del Duero is located on the extensive, elevated northern plateau of the Iberian Peninsula. It occupies the southern plains of the province of Burgos, extends west into Valladolid and includes parts of Segovia and Soria provinces to the south and east, respectively. As its name suggests, the region follows the course of the Duero river for approximately 115 km upstream from Valladolid and is around 35 km at its widest. The region is located around the younger stretches of the river, which later passes through the nearby Toro and Rueda regions before traversing the famous Portuguese growing areas of Douro and Porto, where it drains into the Atlantic Ocean.

Geologically, tertiary sediments, consisting of gently lenticular layers of silty or clayey sand, alternate with layers of limestone, marl and chalky concretions. The Duero valley, formed during the Miocene period, has a flat, rocky, gently undulating terrain, ranging from 911 m down to 750 m above sea level. The national highway N122 follows the river valley.

The Ribera del Duero has moderate to low rainfall (450 mm per year) and is exposed to quite extreme climatic conditions; long, dry summers with temperatures of up to 40 °C are followed by hard winters during which temperatures may fall as low as -18 °C. There are also marked variations in temperature within each season. The climate is continental and Mediterranean, with more than 2,400 hours of annual sunlight.

Vineyards occupy around 120 km² of the region, most of which are situated in the province of Burgos, with around 5 km² in Valladolid and 6 km² in Soria.
