Named for a priory: the Carthusian monks of Scala Dei planted these terraces in the twelfth century and ran the vineyard until the desamortización of 1835 stripped the monasteries of their lands. Phylloxera then emptied the hills, and by the 1980s only a few hundred souls remained in the villages.
In 1989 a handful of pioneers — René Barbier, Álvaro Palacios and their companions — founded their "clos" among the ruins, and the scores of the 1990s did the rest: in 2000 Priorat became Spain's second DOCa, after Rioja. The vines root vertically, metres down into the fractured llicorella slate, and give some of the lowest yields in Europe — dense, mineral wines wrung from an almost unfarmable land.
