La Vizcaína is a project from Raúl Pérez that explores the hillside crus around his hometown of Vatuille de Abajo. Four reds and one white, all from single vineyard sites, are produced under the name, and all from vines with over fifty years of average age (some much older). All the red wines Raúl produces in the Bierzo D.O. are labelled as 100% Mencía, but in fact most of them contain significant quantities of other local grapes. Curiously, Mencía and Alicante Bouschet are the only varieties approved by the D.O., hence the practice of simply labeling the wines as Mencía..
