Finca Río Negro produces wines from Castilla, Spain's vast central plateau. The winery's portfolio spans both single varietals and blends, drawing on the region's continental climate and diverse terroirs. Cerro del Lobo Syrah, the flagship red, showcases the dark-fruited intensity that Syrah expresses across Spain's interior. The blend 992—a four-grape composition of Syrah, Tempranillo, Merlot, and Cabernet Sauvignon—reflects the winery's approach to combining local and international varieties. A Gewürztraminer rounds out the range, an aromatic white that stands apart in a region historically defined by reds. The wines have been assessed by Wine Advocate, Decanter, Wine Enthusiast, and Wine Spectator.
