The mainstream quality wine regions in Spain are referred to as Denominaciones de Origen (similar to the French Appellations) and the wine they produce is regulated for quality according to specific laws.


In compliance with European Commission Regulation (CE) 753/2002, Spanish wines are classified into two categories, which in turn are further classified into sub-categories depending on the strictness of the criteria applied in producing the type of wine in question.


 Although almost all wine regions are confined to specific centres of production, some of the top denominaciones (Cava and Rioja in particular) are the product of more than one Autonomous Community. This is in contrast to Vinos de Pago, where the location criteria are very strict indeed, often centering on specific plots of land and admitting only those wines produced in their immediate vicinity.
