Riaza

Sierra Foothills Rhône and Spanish varietals with elevation-driven structure.

Riaza produces Rhône and Spanish-inspired wines from El Dorado County in California's Sierra Foothills. The winery focuses on varietals suited to the region's warm, elevation-driven climate: Monastrell, Syrah, Grenache, Tempranillo, Graciano, and Zinfandel. Prospector, a Monastrell, anchors the portfolio and has earned recognition from Wine Enthusiast. Unorthodox, a Shiraz expression, and Diablo Rojo, a field blend of Grenache, Tempranillo, Graciano, and Zinfandel, round out the core offerings. The Sierra Foothills terroir—marked by diurnal temperature swings and well-draining soils—suits these varieties' ripening patterns and structural development. Riaza's selections reflect the region's capacity for bold, textured reds with the mineral precision and acidity that elevation provides.
