Mendoza

Mendoza is Argentina's largest wine-producing region, set in irrigated desert oases east of the Andes. Malbec anchors its international identity, while elevation, intense sunlight, cool nights, alluvial soils, and Andean meltwater shape Luján de Cuyo, Maipú, the Uco Valley, and other districts.

Notable factMendoza produces most of Argentina's wine, yet its vineyards span multiple oases and officially recognized geographic indications rather than one continuous growing area.

Overview

Mendoza's vineyards occupy a series of cultivated oases within a dry continental landscape. Irrigation channels distribute Andean snowmelt across alluvial fans and river deposits, while vineyard elevations generally increase toward the mountain front.

Altitude, latitude, slope, and distance from the Andes produce substantial temperature and sunlight differences. Luján de Cuyo, Maipú, the Uco Valley, and eastern and southern districts contain increasingly specific geographical indications and established vineyard communities.

Malbec is the principal reference point, joined by Cabernet Sauvignon, Bonarda, Chardonnay, Torrontés, and many other grapes. This structure should guide users from Mendoza toward its departments, GIs, vineyards, grapes, producers, and wines rather than imply one high-altitude style.

Regional Identity

Mendoza combines high-desert viticulture, irrigation from Andean meltwater, and a wide elevation range. Malbec is central, but regional identity also includes traditional large-volume districts and increasingly site-specific mountain-front wines.
