Lontue Valley, in central Chile, is a sub-region of the larger Curico Valley. It encompasses three smaller valleys: Claro, Tutuvén and Loncomilla; these three names are rarely seen on a bottle of Chilean wine. The principal grapes of Lontue are Cabernet Sauvignon and Sauvignon Blanc. This small area enjoys a Mediterranean climate, with most precipitation in the winter; there is excellent diurnal variation between day and nighttime temperatures. Soils are limestone and volcanic rock and are relatively fertile, resulting in healthy yields for production of approachable, elegant reds and whites that are moderately priced. (Wine/Appellations)
