The Mendoza Province is one of Argentina's most important wine regions, accounting for nearly two-thirds of the country's entire wine production. Located in the eastern foothills of the Andes, in the shadow of Mount Aconcagua, vineyards are planted at the some of the highest altitudes in the world with the average site located 1,970–3,610 feet (600–1,100 meters) above sea level. The principal wine producing areas fall into two main departments-Maipú and Luján which includes Argentina's first delineated appellation established in 1993 in Luján de Cuyo. The pink-skinned grapes of Criolla Grande and Cereza account for more than a quarter of all plantings but Malbec is the region's most important planting followed closely by Cabernet Sauvignon, Tempranillo and Chardonnay. Mendoza is considered the heart of the winemaking industry in Argentina with the vast majority of large wineries located in the provincial capital of Mendoza.
