Ferrandes produces wine on Pantelleria, a volcanic island off Sicily's southern coast where Muscat of Alexandria thrives in an austere Mediterranean climate. The winery's Passito di Pantelleria—a fortified dessert wine made from sun-dried Muscat grapes—represents the island's singular expression of this ancient variety. The wine's concentration and depth emerge from Pantelleria's intense heat and mineral-rich volcanic soils, conditions that have shaped viticulture here for centuries. Passito di Pantelleria is a wine of considerable structure and sweetness, built on the natural sugar of raisined fruit. Wine Spectator, Wine Enthusiast, and Wine Advocate have all assessed Ferrandes' work, recognizing the technical precision required to balance the grape's inherent richness with the wine's fortified character.
