Located west of Santiago, this small, enclosed valley opens out to the Pacific Ocean. The close proximity of the sea gives the region a strongly maritime climate, with morning fog that typically burns off by noon, warm, clear days, and cooling evening breezes. As in all of Chile’s winegrowing regions, rainfall is concentrated in the winter months, providing a long, dry growing season.

The soils are mostly sandy loam with low fertility. This combination of a cool climate and sandy soils is ideal for producing white varieties, such as Chardonnay and Sauvignon Blanc, and the region is also gaining a reputation for Pinot Noir and Merlot as well
