Aconcagua region
Although the Aconcagua wine region is relatively small, it takes its name from the highest peak in South America (Mount Aconcagua), with a reputation for producing some of Chile's finest wines that reach similar heights. The Aconcagua region itself was originally considered too hostile for grapes to survive. The climate plays an important role in the region; it is characterized by typically warm summers and mild winters with a large difference in diurnal temperatures during the day. The foothills of the valley receive little rain but are irrigated by meltwater flowing down from the towering mountains, which encourages the growth of grapes.
The sub-region: Casablanca Valley
The Casablanca Valley is a wine-producing subregion of Chile, located 100 kilometers northwest of the country's capital, Santiago. As it is only 30 km from the Pacific Ocean, the Casablanca Valley is strongly influenced by the cooling effects of the Humboldt Current, which flows up the west coast of Chile from Antarctica. Given the valley's location (much closer to the equator than any European vineyard), viticulture is possible here largely due to oceanic influence, which brings cool morning fog and more cloud cover. important than what is found elsewhere in northern Chile. It is best known for its crisp white wines, particularly from the Sauvignon Blanc and Chardonnay grape varieties which have earned it recognition as one of Chile's quality wine regions. Pinot noir, which is sensitive to the cooler climates found in this coastal area, is also grown with some success.
