Almaviva was established in 1996 by Baron Philippe de Rothschild of Château Mouton-Rothschild and Concha y Toro. Their aim was to create the first Bordeaux Grand Cru Classé equivalent in Chile. With 40 hectares of Concha y Toro's best Puente Alto vineyards being dedicated to the task and the steady hand of Patrick Leon (winemaker at Mouton and Opus One), the results have been nothing short of spectacular. Located in the Maipo Valley, in Chile's central zone, Puente Alto was recognized over twenty years ago as offering ideal conditions for growing the Cabernet Sauvignon grape. It is here that 85 hectares have been reserved exclusively for Almaviva. Characteristic features of Puente Alto include its stony soil, cold, rainy winters, and the hot days and cool nights of its summers. The Almaviva vineyard is tended with meticulous care from pruning to harvest. A revolutionary underground drip irrigation system has been installed, making it possible to deliver the precise amount of water that each vine needs with a constant concern for quality.
