In the far west of the country, only a (substantial) mountain range from Santiago in Chile, this is by far the biggest and most important wine-growing province in Argentina, accounting for more than 70% of all Argentina’s wine production, although the area planted has declined from a peak of 255,000 ha/629,850 acres in 1980 to 159,137 ha/394,500 acres in 2013. The Andes dominate the western skyline, with Mount Aconcagua, at 6,960 m/22,837 ft, the highest mountain in the Americas. Vineyard elevations range between 600 to 1,600 m (1,970 to 5,249 ft) above sea level.
