The Central Valley (El Valle Central) of Chile is one of the most important wine-producing areas in South America in terms of volume. It is also one of the largest wine regions, stretching from the Maipo Valley (just south of Santiago) to the southern end of the Maule Valley. This is a distance of almost 250 miles (400km) and covers a number of climate types. The Central Valley wine region is easily (and often) confused with the geological Central Valley, which runs north–south for more than 620 miles (1000km) between the Pacific Coastal Ranges and the lower Andes.
