Abbreviation (also AOVDQS) for the quality designation "(Appellation d'Origine) Vin Délimité de Qualité Supérieure" formerly used in France, which was created in 1949 as a preliminary stage for the highest quality level AOC (now AOP). With the EU wine market regulation in force from 2009, it was only permitted until the end of 2012. For the high classification to AOP, the production conditions must be prepared according to AOP standards and the reference to the terroir must be proven. Otherwise, the wine is classified back to IGP (Indication Géographique Protégée). See also a comprehensive description of the topic under Quality System.
