South America Wine Maps

A Visual Guide to the Andes: Chile & Argentina

South American wine is defined by the spine of the continent: the Andes Mountains. To the west, Chile is a study in latitude and proximity to the ocean, a sliver of land where the cooling Humboldt Current meets the coastal ranges. To the east, Argentina is a study in altitude, a high desert where vines climb to some of the highest elevations on the planet to find relief from the sun.

Understanding the terroir of South America requires visualizing this dramatic topography. These high-resolution maps are designed to break down the vast distances and distinct climates of the countries. Cross-referenced with data from Wines of Chile and Wines of Argentina, they provide the geographic context needed to distinguish the coastal Sauvignon Blancs of Leyda from the high-altitude Malbecs of the Calchaquí Valleys.

Unlock the gallery below to explore the detailed wine geography of:

  • Northern Chile: The arid frontiers of the Atacama and the transverse valleys of Coquimbo (Elqui, Limarí).
  • Chile’s Central Valley: The historic heartland of Maipo, Rapel (Cachapoal/Colchagua), and Maule.
  • The Chilean South: The old-vine heritage of Itata, Bio-Bío, and Malleco.
  • Northern Argentina: The extreme altitudes of Salta, Tucumán, and Catamarca.
  • The Cuyo Region: Detailed views of San Juan’s valleys, including Pedernal and Zonda.

Region Breakdown: What These Maps Reveal

Chile: Latitude and The Ocean

Chile is an “island” of viticulture, isolated by deserts, mountains, and oceans. Our maps follow the country’s immense length to illustrate the shift in climate.

  • The North & Aconcagua: Visualize the transition from the Pisco-producing regions of Atacama down to the limestone soils of Limarí. See how the Casablanca and San Antonio valleys open directly to the sea, acting as funnels for cold maritime air.
  • The Central Valley: This map disentangles the famous rivers that feed the Cabernet Sauvignon heartland. Trace the Maipo, Rapel, and Maule rivers as they flow from the Andes to the sea, creating the alluvial terraces that define the region.
  • The South (Sur): Experience the shift to a greener, wetter landscape. Our map highlights Itata and Bio-Bío, home to centuries-old Bush Vine Cinsault and País, showing their coastal orientation distinct from the Central Valley to the north.

Argentina: Altitude and The Desert

While Chile relies on the ocean, Argentina relies on the mountains. Our maps emphasize the verticality of the terroir.

  • The North (Salta & Catamarca): This map captures some of the highest vineyards in the world. It details the Calchaquí Valleys (home to Cafayate), illustrating how the mountains create a sheltered, high-altitude corridor essential for Torrontés and Malbec.
  • San Juan & La Rioja: Often overshadowed by Mendoza, San Juan is a powerhouse of diversity. We visualize the distinct valleys of Tulum, Zonda, and the exciting high-altitude Pedernal Valley, showing how they sit nestled against the Andean foothills.
