Chile 3D Wine Map: Coast to Andes on Real Terrain

Casablanca, Maipo, Colchagua, Maule, and Chile’s wine valleys from coast to Andes.

This interactive 3D Chile wine map shows the country’s 6 wine regions and 25 valleys and zones on real terrain, from Elqui and Limarí in the north through Casablanca, Maipo, Colchagua and Maule to Itata, Bío-Bío and Osorno, drawn in 3D by SommGeo. Tilt and fly from the Pacific over the Coastal Range to the Andes, check elevation and slope, and run the daylight and shadow animation. Click any valley and a profile opens with its grapes and character. The interactive map is part of SommGeo membership, which starts with a free 15-day trial.

• Regions on the map: 6 regions and 25 valleys and zones, every boundary clickable
• Shape: Squeezed between the Pacific and the Andes, never much more than about 350 km wide
• Coastal Range: Shields the Central Valley from Pacific fog; gaps like Casablanca and Leyda let cool air in
• Andes: Snowmelt irrigates the valleys, and cold air flows down from the peaks at night
• Signature grapes: Cabernet Sauvignon, Carmenère, Sauvignon Blanc and País
• 3D tools: Tilt and rotate the terrain, elevation and slope readouts, daylight and shadow animation and a weather overlay

Chile’s wine geography is shaped by three forces you can see in the terrain: the Andes to the east, the Pacific Ocean to the west, and the north-to-south stretch of latitude across roughly 1,300 kilometers (808 miles) of vineyard land. The country is narrow enough that virtually every wine region sits between these two walls, and the interplay between Andean altitude, Pacific fog driven by the cold Humboldt Current, and the Central Valley floor between them defines what grows where.

What You’ll Explore

This 3D Fast Map covers Chile’s wine regions from the Atacama in the north through the Central Valley heartland to Bío-Bío, Malleco, and the newer Osorno in the south.

Key Regions in Focus

The Coastal Valleys: Casablanca and San Antonio

Casablanca and the neighboring San Antonio Valley (including its sub-zone Leyda) sit in the Coastal Range between Santiago and the Pacific port of Valparaíso. These are Chile’s cool-climate success stories. The Humboldt Current, which runs cold along the entire Chilean coast, drives morning fog and cool marine air through gaps in the Coastal Range, dropping temperatures well below the warm Central Valley floor just a few kilometers inland. Casablanca, planted from scratch in the 1980s, proved that Chile could produce Sauvignon Blanc, Chardonnay, and Pinot Noir with freshness and acidity that the warmer inland valleys could not match. San Antonio/Leyda pushes even closer to the ocean, with some vineyards within 4 kilometers (2.5 miles) of the coastline. The 3D terrain shows the coastal gap that funnels this influence inland.

The Central Valley: Maipo and Colchagua

The Central Valley (Valle Central) is the traditional heart of Chilean wine, running north to south between the Coastal Range and the Andes. Maipo, closest to Santiago, has long been associated with Cabernet Sauvignon, particularly from the Alto Maipo sub-zone in the Andean foothills where elevations range from roughly 400 to 800 meters (1,300 to 2,625 ft) and the wines take on more structure and complexity. Colchagua, further south in the Rapel Valley, is warmer and broader, producing ripe, concentrated reds from Cabernet Sauvignon, Carmenère, and Syrah. The east-to-west gradient within each valley is the key geographic story: the Andes designation (higher, cooler, later-ripening) versus Entre Cordilleras (valley floor, warmer) versus Costa (Pacific-influenced). The 3D terrain makes this lateral dimension visible.

The Southern Frontier: Maule, Itata, and Bío-Bío

South of the Central Valley heartland, Maule, Itata, and Bío-Bío represent Chile’s oldest vineyard areas and its current frontier of interest. Maule is the largest wine region in Chile by planted area, and much of it remains in old-vine País (the Mission grape brought by Spanish colonists) and Carignan, particularly in the drier, unirrigated coastal and hillside sections. Itata and Bío-Bío, further south, are cooler and wetter, with old-vine Muscat of Alexandria, Cinsault, and País on granitic soils. These southern regions have become a focus for producers looking for freshness, lower alcohol, and a connection to Chile’s pre-industrial viticultural roots.
