Tenuta Regaleali operates in Terre Siciliane, the expansive wine region of southern Sicily. The winery's portfolio centers on indigenous and international varieties suited to Sicily's Mediterranean climate. Riserva del Conte, a blend of Nero d'Avola and Perricone, represents the winery's engagement with native Sicilian grapes—varieties that thrive in the island's warm, dry conditions and bring dark fruit and structural complexity to the glass. Vigna San Francesco Cabernet Sauvignon demonstrates the winery's work with the classic Bordeaux variety, while Grillo Mozia Fondazione Whitaker showcases the crisp, mineral character of Grillo, a white grape native to western Sicily. The winery's wines have been assessed by Wine Advocate, Wine Enthusiast, and Decanter.
