Mendoza is by far the largest wine region in Argentina. Located on a high-altitude plateau at the edge of the Andes Mountains, the province is responsible for roughly 70 percent of the country's annual wine production. The French grape variety Malbec has its New World home in the vineyards of Mendoza, producing red wines of great concentration and intensity.
The province lies on the western edge of Argentina, across the Andes Mountains from Chile. While the province is large (it covers a similar area to the state of New York), its viticultural land is clustered mainly in the northern part, just south of Mendoza City. Here, the regions of Lujan de Cuyo, Maipú, San Martín, Rivadavia and the Uco Valley are home to some of the biggest names in Argentinian wine.
