Condominio Ribera Del Duero

The region is characterised by a largely flat, rocky terrain and is centred on the town of Aranda de Duero, although the most famous vineyards surround Peñafiel and Roa de Duero to the west. 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 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 byhard 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.
