The Valle de Colchagua wine-growing area is located 130 kilometres south of the Chilean capital Santiago de Chile in the Valle Central. Together with the Cachapoal area to the north, it forms the southern half of the Rapel region. The centre is the town of Rancagua, known for its hot thermal springs. The River Tinguiririca flows through Colchagua, making viticulture possible in the first place. The hot Mediterranean climate is tempered by cool air currents from the Pacific Ocean to the west. The first Chilean wine route "Ruta del vino de Colchagua" was created here in 1996. A wine tourism attraction is the "Tren del Vino" train, which is operated by a steam locomotive and travels through the vineyards.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
