Languedoc-Roussillon is the largest region in terms of vineyard surface and production, hence the region in which much of France's cheap bulk wines have been produced. So-called "wine lake", Languedoc-Roussillon is also the home of some innovative producers who combine traditional French wine like blanquette de Limoux, the world's oldest sparkling wine, and international styles while using lessons from the New World. Much Languedoc-Roussillon wine is sold as Vin de Pays d'Oc.
