Mendoza accounts for over half of Argentina's wine production and a huge percentage of the wine production of South America in it's entirety. It's proximity to mountainous terrain - Mendoza lies just East of the Andes Mountain range, shelters the vineyards, most of which are planted on the flat lands, from wind and rain. Mendoza's vineyards are among the highest in the world with an altitude of 1100 metres above sea-level.
In the past 20 years Mendoza has become almost synonymous with the bold red grape Malbec, formerly known for fleeting appearances in Bordeaux blends, Malbec has risen to prominence off of the back of Mendoza's similar vault up among the elite regions of the world. Other important grapes in grown in Mendoza include Cabernet Sauvignon, Tempranillo and Chardonnay.
Mendoza can be broken down into two major sub-regions, Maipú and Luján, the latter being the first of Argentina's delineated appellations when it was established in 1993.
