Castiadas produces wines from Sardegna, the Mediterranean island region of southern Italy. The winery's portfolio centers on indigenous varieties suited to Sardinia's sun-drenched terrain. Capo Ferrato Cannonau di Sardegna, made from Cannonau—the island's signature red grape—represents the winery's work with this dark-skinned variety. On the white side, Castiadas offers Vermentino di Sardegna and Cala dei Mori Vermentino di Sardegna, both expressions of the crisp, mineral-driven white that thrives in Sardinian vineyards. Wine Enthusiast and Wine Spectator have rated these wines, reflecting their presence in the broader critical conversation around Sardinian production.
