The current law for the Côtes du Rhône Appellation d'origine contrôlée dates only from 1937, but there is a long history of attempts to regulate the quality of the wine from the region. In 1737 the Conseil d'Etat issued a royal decree on the production of wine in Roquemaure. It specified that neither wine nor harvested grapes could be brought into town from outside the area and to prevent wines from a poor vintage being passed off as coming from a better vintage, barrels of wine from Roquemaure and the surrounding villages had to be marked on one end using a hot iron, with the letters "CDR" for Côte du Rhône and the year. The surrounding villages were listed as Tavel, Lirac, Saint-Laurent-des-Arbres, Saint-Geniès-de-Comolas, Orsan, Chusclan, Codolet and "others of high quality". The decree also suggested that it would help to prevent fraud if the barrels were marked with the name of the parish of origin. Another decree issued in the same year complained about the poor quality of the barrels used for the wine and specified that they should be manufactured in two standard sizes.
