One of the six major regional IGP areas for the production of local wines in France. The other five are Atlantique, Comtés Rhodaniens, Comté Tolosan, Méditerranée and Val de Loire. Situated deep in the south-east of the country on the Mediterranean, it includes the double region of Languedoc-Roussillon and the right-hand part of the southern Rhône in the five departments of Aude, Gard, Hérault, Lozère (only 6 communes) and Pyrénées-Orientales. The name "oc" in the Occitan language means "yes", from which the "oui" has evolved. Langue d'Oc means "language of Oc" in Occitan. From the 2009 vintage onwards, a three-level quality hierarchy was created. The lowest level is "Séduction" followed by "Style" and the highest level "Collection".
