Curico Valley is a wine-producing region in Chile's Central Valley. It is divided in two: the sub-region of Teno covers the northern part of the valley, and Lontue is in the south. The valley is roughly 115 miles (185km) south of the Chilean capital, Santiago, and is located at a latitude of 35°S – a similar proximity to the Equator as the southern tip of Spain. Curico Valley is known for its reliability and produces good-value, everyday wines from Cabernet Sauvignon and Sauvignon Blanc.
The valley was the region chosen by Miguel Torres when he began his Chilean wine enterprises in 1979, bringing with him from Spain a number of technological advances that had a significant impact on the Chilean wine industry. In those days, Curico was considered to be a part of the Maule wine region, but it is now recognized as a region in its own right. The presence of several well-respected and well-established wineries in Curico almost certainly supported the case for its individual recognition.
The valley's climate is varied. The eastern part – closer to the Andes Mountains – is cooler than the western as it benefits from breezes coming down from the slopes of the Andes. In this way, it differs from regions further north, where the western ends of the valleys, being influenced by the Pacific Ocean, are generally cooler. In Curico, however, the hills of the Coastal Ranges dissipate the effect of east–west air movements. The major centers of production and the established names of Curico Valley wine (Echeverria, Montes, San Pedro, Torres and Valdivieso) are located around the cooler eastern towns of Curico and Molino.
The meltwater rivers Lontue and Teno that flow through Curico Valley before converging to form the Mataquito River have a significant effect on viticulture here. The region's soils are derived from limestone and volcanic rock from the Andes and have been deposited in the valley over time by the rivers (alluvial) as well as by gravity (colluvial). While these soils are slightly more fertile than in other, more quality-focused wine regions of Chile, they are sufficiently high yielding to cement Curico Valley's reputation as a quality bulk-producing region.
Curico's vineyards are planted with more varieties than anywhere else in Chile. The dominant grapes, however, remain the same as they were when the region first appeared on the international wine map: Cabernet Sauvignon and Sauvignon Blanc. Curico may have yet to produce a Cabernet Sauvignon to rival Maipo's red wines and its Sauvignon Blanc still does not match the fresh, complex style found in Casablanca, but the valley is one of Chile's workhorse regions and its output is consistent and reliable.
