Zenner operates in Sicilia, the sprawling Mediterranean island appellation within Southern Italy's Terre Siciliane region. The winery's Terra delle Sirene Nero d'Avola draws from the native Nero d'Avola grape, Sicily's signature dark variety—a wine that has earned recognition from Wine Enthusiast and Wine Advocate. Nero d'Avola thrives in Sicily's warm, sun-soaked climate, developing deep color and ripe dark fruit character with the structure to age. Terra delle Sirene represents the winery's expression of this indigenous varietal, rooted in the terroir and traditions of the island's wine landscape.
