The Elqui Valley is centered on the Elqui River in northern Chile, 400 km (250 mi) north of Santiago. It lies at the southern end of the Atacama Desert in the Coquimbo region and is known for producing table grapes and other fruits, as well as pisco, but it is also one of the most commercially viable wine-producing regions of northern Chile. The region’s vineyards extend from the Pacific Ocean in the west to the Andes Mountains in the east, and rise to an elevation of 6,500 feet. Wine production began in the Elqui Valley in the 1990s when Chilean wine producers began to look at potential viticulture sites outside the Chilean Central Valley; since then, 286 ha (707 acres) of vines have been planted, mostly along the River Elqui valley, where grape growers have access to high-quality water for irrigation.

The region is characterized by a sunny, desert-like climate, less than 70 millimetres (2.8 in) of annual rainfall, dry rocky terrain, steep valleys and temperate hills cooled by strong winds from the Pacific Ocean and the Andes Mountains, producing excellent results for varieties like Syrah.
