Castilla y Leon
Castilla y Leon is the largest of Spain's 17 administrative regions, covering around a fifth of the country's total area. It stretches approximately 350 kilometers from central Spain to the northern coast and connects the Rioja wine region to the Portuguese border. In terms of climate, Castilla y Leon has a remarkably strong continental character with its proximity to the Atlantic Ocean. Hot, dry summers are followed by harsh, cold winters where temperatures regularly drop well below freezing. Changes in temperature over the course of a day are just as pronounced and play a vital role in the style of local wines. Cool nights refresh the vineyards after long hot days.
The sub-region: Ribera del Duero
Ribera del Duero is an important wine-growing region in Castile and Leon in northern Spain. Its reputation is largely due to the high quality of its red wines made mainly from Tempranillo grape varieties. Ribera del Duero is located on the northern plateau of the Iberian Peninsula at 800 meters above sea level. Ribera del Duero means "bank of the Duero", a river that divides the region in two. It also provides local vineyards with a much-needed water supply. The region's inland location, coupled with the protective effects of the Sierra de la Demanda and Sierra de Guadarrama mountain ranges, creates an extreme climate. Hot, dry summers are followed by harsh winters.
