Mendoza's wine region is over 144,000 hectares of planted vineyards. This covers 75% of the Argentina’s vineyards. Malbec is the region’s most celebrated grape. Argentina's most highly rated Malbec wines originate from Mendoza's high altitude wine regions of Lujan de Cuyo and the Uco Valley. These Districts are located in the foothills of the Andes mountains between 2,800 and 5,000 feet (850 and 1,520 m) elevation.


Patagonia is a desert, and viticulture is possible only near the rivers, where meltwater from the Andes is abundant. There are the two viticultural regions located in its northern section in one of the country’s richest water supply: the pioneering Rio Negro and the newer and still developing Neuquen. As a result of the areas cooler climate and higher latitude, wines from these two zones are traditionally more European in style than those from the central and northern regions of Argentina. While Malbec still plays a principal role in Patagonian wine, it is Pinot Noir that has become the region's iconic grape variety. The excellent white wines made from Chardonnay, Sauvignon Blanc and Riesling also showcase the freshness of the region's climate. There is a need also to mention the New Patagonia wines: the valleys of Chubut and La Pampa. Valley of Chubut is located in the heart of Andean Patagonia. The vineyard is flourishing by getting good results from growing Riesling, Pinot Noir and Merlot. La Pampa located at the extreme north of Patagonia, produces the main varieties of Argentina.
