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 Reventón, a 1 ha parcel of around 70 year-old Garnacha at 900 meters above sea level, is planted on just such a rare outcropping of slate. It stands in contrast with Dani’s other wines, both under his name and those he makes with Fernando Garcia at Comando G, as more wildly aromatic, darker, richer and with a firmer structure. Broken into two sections by the crest of a hill, each parcel in exceptional vintages such as 2016, is fermented, aged and bottled separately.
