The "Organisation Internationale de la Vigne et du Vin" (International Organisation of Vine and Wine) is an international and supranational body based in Paris (France) that represents the interests of viticulture in the areas of grapevine, wine, wine-based beverages, table grapes, sultanas and other vine products of currently 46 member states. In 2001, a reorganisation and change of name took place (previously "Office International de la Vigne et du Vin"). The tasks of the new organisation were modernised and adapted. The predecessor organisation was founded in 1924 (jointly by the countries of France, Greece, Italy, Luxembourg, Portugal, Spain, Tunisia and Hungary) during Prohibition in the USA (1920-1933) with the mission of spreading the positive effects of wine consumption, coordinating research and nomenclature and ensuring good quality standards in production. Even during the Second World War (1939 to 1945), the work continued uninterrupted under the protection of diplomatic immunity.
