““In Argentina, such as in most of the New World wine producing countries, there is no controlled designation of origin system, although some winemakers are working towards establishing a structure where the region in which wines are made can become more distinguished. Argentina is the fifth largest wine producing country in the world, and has three main wine regions: the northern region which includes Salta, Catamarca and la Rioja; the central region, where San Juan, Mendoza and Córdoba are located; and the south, with Río Negro and Neuquén. More than 50% of Argentina's wine is produced in Mendoza.””
