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 80+-year-old Garnacha at 950 meters above sea level, is planted on just such a rare outcropping of slate. It stands in contrast with Comando G’s other wines 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.
