The Vin de Pays d'Oc encompasses the Languedoc and Roussillon regions that take in a huge swathe of vineyards from the vineyards of the Rhône all the way to the Pyrenees on the Spanish border. The vast region borders the Mediterranean, which provides cooling influences during the warm southern French summers and moderated temperatures during the winter. The Vin de Pays d'Oc designation is responsible for 80% of Vin de Pays production in France, and only the very best of this is ever exported. The region is best known through the portfolios of major brands. All of France's classic varieties are grown in this region. (Wine/Appellations)
