Just west of Santiago lies a rich agricultural region known as the Central Valley. This is the heart of Chile’s wine industry, which, after years of producing more wine in quantity than of quality, has taken its place amid the great producers of the world. It’s no longer difficult to find elegant character-rich Chilean wines that are expressive of the region from which they come. Many wine labels now indicate the location of vineyards with the terms “Costa” (near the sea), “Entre Cordilleras” (in the Central Valley) and “Andes” (closer to the mountains). The Andes and the ocean have at least as much impact on the terroir of a vineyard site as its latitude does.
