In the clay loam soils of El Alto Vineyard in Ugarteche, Luján of Cuyo, we selected the poorest profiles – resulting from the mixture of pebbles, gravel and clay – to plant our Doña Paula Estate Cabernet Sauvignon in 1998. These vines yield 7 to 9 tons per hectare and they are trained in espaliers, using drip irrigation. The climate of this estate, located at 1,050 meters (3,445 feet) above sea level, is characterized by its warm days and cool nights, with an average temperature variation of 14 °C (57.2 °F) and an average annual rainfall of 250 mm (9.8 in). At Doña Paula, our vineyards have always been managed using sustainable agricultural practices.
