Casa Gualda produces wines from Castilla, Spain's expansive central plateau, where continental climate and high elevation shape bold, structured reds. The winery works primarily with Iberian varieties and international grapes suited to the region's demanding terroir. Plus Ultra, a Petit Verdot, leads the portfolio with depth and aging potential. Syrah follows with the aromatic intensity and peppery structure characteristic of the variety. Singular blends Bobal, Syrah, and Tempranillo—a combination that marries local tradition with modern winemaking. These wines have drawn assessment from major critics including Wine Advocate, Wine Spectator, Wine Enthusiast, Decanter, and Falstaff, reflecting their technical merit and consistency across vintages.
