Marqués de Griñon operates in Dominio de Valdepusa, a distinctive corner of Castilla in central Spain. The winery focuses on Garnacha in its various expressions—the dark, structured Garnacha Tintorera and the more elegant red Garnacha—alongside traditional Spanish varieties like Tempranillo, Graciano, and Mazuelo. Las Garnachas de El Rincón, a blend of Garnacha Tintorera and Garnacha, represents the house's commitment to these indigenous grapes, as does the single-varietal El Rincón Garnacha Tintorera. Enartis, a Garnacha-led blend with Tempranillo, Graciano, and Mazuelo, rounds out the portfolio. The wines have been assessed by Wine Enthusiast, Wine Spectator, Decanter, and Wine Advocate, reflecting their standing within the Spanish wine conversation.
