DOC (formerly DOCa) - Denominación de Origen Calificada, is the highest category in Spanish wine law, reserved for regions with above-average grape prices and particularly stringent quality controls. Rioja was the first Spanish region to be awarded DOC status in 1991, followed by Priorat in 2003. Priorat calls itself DOQ - Denominacio d'Origen Qualificada (Catalan) These are the only two regions considered "above" DO status.
