Raúl Pérez works in Bierzo, the slate-soiled region of Castilla y León where Mencía thrives as the signature red grape. The winery's portfolio centers on this variety and its regional companions—Garnacha, Verdello, and obscure local cultivars that speak to Bierzo's terroir specificity. A Trabe, a field blend of Garnacha, Verdello, Mencía, Bastardo Magarachsky, and Zamarrica, represents the winery's commitment to the region's ampelographic complexity. El Cerro de Valdecañada and Ultreia de Paluezas Mencía are pure expressions of the estate's primary varietal, each capturing the mineral precision and dark-fruit intensity that define quality Bierzo. The wines have been assessed by Wine Spectator, Wine Advocate, Decanter, Wine Enthusiast, and Falstaff.
