Aconcagua is one of the five principal wine regions of Chile.
It is a Denomination of Origin (DO) defined by the Chilean Appellation system, the legally defined and protected geographical indication used to identify where the grapes for a wine were grown.
The snow-capped peak of Aconcagua and the surrounding mountains delivers essential melt water to the valley below.
The small, 1,098-hectare winegrowing area is well known for its red wines, which have earned international acclaim, with Vina Errázuriz's “Seña” placing ahead of both Château Lafite and Château Margaux in blind tasting held in Berlin in 2004,[2] a milestone for the Chilean wine industry.
[citation needed] Although the valley is primarily known for the red grapes grown in its interior, white grapes are also now being grown in new coastal plantations.
