The Leyda Valley lies to the west of Santiago, around 8 kilometres from the Pacific Ocean and 40 kilometres from Casablanca. Its closeness to the sea makes it one of the coolest growing sites in Chile. It is one of the four sectors that make up the San Antonio province, a sub-region of the Aconcagua Valley; the others being Lo Abarca, Rosario, and Malvilla. Until recently, crops such as wheat and barley were predominantly grown in the Leyda Valley, but in 1997 the Fernandez family, together with Gustavo Llona, recognised the potential of the area for growing grapes and established Viña Leyda. The first harvest of Pinot, Sauvignon and Chardonnay took place in 2001, and there are now 216 hectares under vine.
