The Maipo Valley is a large complex wine region; drier and warmer than cooler regions to the north such as Casablanca, Leyda and San Antonio. Annual rainfall in Maipo is very low due to its distance from the coast and being surrounded by hills. Conditions during the growing season are of warm days and cool nights. As such, Maipo is more suited to red grape varieties and is firmly established as a producer of world-class Cabernet Sauvignon. The alluvial soils in Maipo allow for grapes, and resulting wines, that are concentrated with soft tannins and roundness.
