The Denominacion de Origen of Ribera del Duero was founded in July 1982 by an organisation of wine producers and growers who were determined to promote the quality of their wines and enforce regulatory standards. Located in the country`s elevated northern plateau, it is an autonomous community within Castilla y Leon. As the name suggests, the region follows the course of the Duero river and includes the areas of Burgos, Valladolid and parts of Segovia. Like Rioja, the region produces wines selected for long ageing and uses the same age categorisation for its products.
