Terroir, identity, qualitative value, pure Sicilian identity. In the panorama of the great quality wine companies, Firriato, in less than three decades, has been able to identify its own and original production path dedicated to enhancing the native vines of the Sicilian tradition. Nero d’Avola, Perricone, Nerello Mascalese, but also Zibibbo, Grillo and Catarratto have become increasingly familiar vines for many consumers, thanks to Firriato. Over yeras of grape harvests, the Di Gaetano family has given life to an oenological design centered on precision viticulture, capable of enhancing and enhancing the varietal peculiarities of each vine planted in well-defined pedoclimatic and terroir contexts. The approach underlying this path to enhance the Sicilian ampelographic heritage, has a consolidated scientific matrix, aimed not only at a wine production of great quality, but also at an operation of conservation and protection of all those cultivars of ancient or of those particular species of vitos with an unknown genome. It is within the Borgo Guarini estate, in the countryside of Trapani, or in the experimental laboratory of Cavanera, on the slopes of Etna, that Firriato works to safeguard the genome of ancient vines (Orange blossom, pink Zibibbo, Lucignola, Inzolia nera, Minnella) or to study varieties with unknown genomes, as in the case of the 8 varieties identified by the research panel of the agricultural faculty of the University of Catania, within the 150-year certified prephylloxera parcel.
