El Reventon comes from the village of Cebreros at an altitude of 950m on a south/south-easterly vineyard plot, planted in 1943. While sandy granite soils with varying amounts of quartz and clay are the norm in the Sierra de Gredos, there are some vineyards on schist and slate soils as well. El Reventon is planted on just such a rare outcropping of slate. This produces wildly aromatic, darker, richer wines with a firmer structure. The wine undergoes around 16-months of barrel-ageing; it feels more Mediterranean in style.
