Castilla y León, as this region is called in Spanish, is a large region in northeastern Spain that includes nearly twenty percent of Spain’s total land. It encompasses eight provinces and five appellations. The best known of the appellations is Ribera del Duero, though the appellations Toro and Bierzo are also gaining international reputations for fine wine. The region is largely a high, flat plateau and red grapes account for much of what is grown in Ribera del Duero. The other appellations are Rueda, known for white wine, and Cigales. Bierzo is known for the full flavored white wine Godello.
