Selección de Bodega Malbec is the result of an assemblage of our best terroirs: Finca El Alto, whose soils are mainly clayey; Finca Alluvia, which has mineral and rocky soils; and Finca Los Indios, which has calcareous and sandy soils. These old vineyards are planted at between 1,050 and 1,350 meters (approximately 3,445 and 4,430 ft) above sea level and have a naturally low yield (between 2 and 3 t/ha [0.81 and 1.22 t/acre]). Surface irrigation is used. The climate typically presents warm days and cool nights, with an average annual rainfall of between 200 and 300 mm (7.87 and 11.81 in). At Doña Paula, our vineyards have always been managed using sustainable agriculture practices.
