I Custodi works the volcanic soils of Etna in Sicily, where the region's distinctive terroir shapes wines of mineral precision and depth. The winery's portfolio centers on indigenous and traditional varieties suited to this demanding landscape. Saeculare Etna Rosso Riserva, a blend of Alicante Bouschet, Nerello Cappuccio, and Nerello Mascalese, represents the darker, structured end of the range. Ante Etna Bianco, built from Carricante, captures the white wine character of the zone—crisp and mineral-driven. Imbris Bianco Superiore rounds out the core offerings. Wines from I Custodi have been assessed by Decanter, Wine Spectator, Wine Enthusiast, and Wine Advocate, reflecting their standing within critical circles. The winery's focus remains on expressing the volcanic character of Sicilian Etna through careful varietal selection and winemaking.
