Rueda is a wine producing region in the heart of the Iberian Peninsula, on the high plateau of Castile and León, right between two of Spain’s most famous red-wine producers: Ribera del Duero and Toro, and just on the North-West of Madrid. The river Duero flows through this region from East to West. Rueda was the first Denominación de Origen to be certified in the Region of Castile and León (1980). This high plateau is characterised by a typical continental climate featuring long cold winters, a brief spring season, and dry harsh hot summers
