Lopez Cristobal produces wines from Ribera del Duero, the prestigious wine region of Castilla y León in Spain. The winery works with the classic grapes of the region: Tempranillo (known locally as Tinta del País) and Merlot, which thrive in the Duero valley's continental climate and slate-rich soils. The Tinto Roble, a blend of Merlot and Tempranillo, represents the winery's approach to oak-aged reds with structure and depth. The Bagús Ribera del Duero, made from Tinta del País, showcases the indigenous character of the region's signature variety. Both wines have been assessed by major critics including Wine Advocate, Wine Enthusiast, and Wine Spectator.
