Zaca Mesa produces wines from Santa Barbara County's Central Coast terroir, where cool maritime influence shapes the character of Rhône and alternative varietals. The winery's portfolio centers on Syrah in its various expressions—the Clydesdale and Amphora Syrah both demonstrate the region's capacity for structured, age-worthy reds—alongside Petite Sirah, which gains depth and complexity in these conditions. Wines from Zaca Mesa have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff. The Petite Sirah, Clydesdale, and Amphora Syrah each carry prestige ratings of 93 points, reflecting the precision and balance achieved across the lineup. Santa Barbara County's diverse microclimates and well-draining soils provide the foundation for wines that balance power with refinement.
