The valley lies across the country, from the Andes Mountains in the southern direction to the Pacific Ocean. The Maipo is approximately 1,000 meters on the east side and 500 meters above sea level on the west side. Because of this natural slope, there are differences in viticulture within the valley. There is a warm Mediterranean climate with the most important characteristics being a dry summer from December to March and an average rainfall of 330 mm per year. The temperature differences at the foot of the Andes can rise to 20 ° C during the wine season. One finds here mainly the well-known red grapes such as Cabernet Sauvignon, Merlot and Carmenère. The wines taste elegant and classic, and especially the Cabernet Sauvignon has a consistently high quality. Undurraga, Concha y Toro, Santa Emiliana and Santa Rita are just a few of the viñas that have their vines here.
