Castro Ventosa produces wines from Bierzo, a distinctive region in Castilla y León known for its slate soils and Atlantic-influenced climate. The winery focuses on Mencía, the region's signature red variety, alongside Godello, a white grape that thrives in Bierzo's cool conditions. Valtuille El Rapolao, a Mencía and Alicante Bouschet blend, represents the winery's red wine expression, while Valtuille El Val showcases Godello's mineral precision. A single-varietal Mencía offering, Valtuille Villegas, rounds out the portfolio. These wines have been assessed by Wine Advocate, Wine Spectator, and Decanter.
