Casale del Giglio operates in Lazio, the central Italian region that frames Rome. The winery's portfolio centers on white wines, with particular focus on varieties suited to the region's warm climate. Biancolella Lazio Faro della Guardia Bianco, made from the indigenous Biancolella grape, represents the winery's engagement with local terroir. Viognier appears across two expressions: a dry Viognier Lazio Bianco and Aphrodisium Vendemmia Tardiva, a late-harvest interpretation of the Rhône variety. Both Viognier bottlings and the Biancolella have drawn assessment from major critics including Wine Enthusiast, Wine Spectator, Wine Advocate, Decanter, and Falstaff. The winery's work with Viognier—a grape known for its full body, stone-fruit character, and aromatic intensity—and its exploration of late-harvest styles suggest a commitment to extracting complexity from warm-climate viticulture.
