Argentina

Argentina is one of the world's major wine-producing countries and the largest producer in South America. Most vineyards follow the western edge of the country, where the Andes separate dry growing regions from Pacific weather and provide meltwater for irrigation. Elevation, abundant sunlight, and pronounced differences between daytime and nighttime temperatures shape many of its best-known wines.

Mendoza is the national center of production and contains a wide range of sites, from established eastern districts to higher vineyards in the Uco Valley and Luján de Cuyo. San Juan adds warm, dry valleys; Salta is recognized for extreme elevation; and Patagonia contributes cooler conditions. Newer projects have also expanded toward the Atlantic coast and other previously overlooked landscapes.

Malbec provides Argentina's clearest international identity, but the country is not defined by one grape. Cabernet Sauvignon, Cabernet Franc, Bonarda, Syrah, Chardonnay, and the aromatic white Torrontés all encourage exploration of its regions, vineyards, producers, and evolving styles.

The most useful path into Argentine wine is geographic: begin with the major provinces, then follow their valleys and recognized indications toward individual sites. This reveals why wines from high, cool sectors can differ from those grown on lower, warmer plains and places each producer within a clearer regional context.
