Casa Rivas produces wines from Santiago, in the Maipo Valley of Chile's Central Valley. The winery focuses on two signature varietals: Cabernet Sauvignon and Carménère, the latter a grape with deep roots in Chilean viticulture. The Reserva Cabernet Sauvignon and Gran Reserva Carmenère represent the core of the portfolio, with the Reserva Carmenère completing the range. These wines have been assessed by Wine Spectator, Wine Advocate, Wine Enthusiast, Falstaff, and Decanter. Maipo Valley's continental climate and alluvial soils favor structured reds with mineral precision—conditions that shape the character of Casa Rivas's offerings. The winery's approach centers on varietal expression through the Reserva and Gran Reserva tiers, reflecting the distinct profiles of Cabernet Sauvignon's architecture and Carménère's darker, spiced complexity.
