Terra Costantino is an Italian winery located in Sicily, at the foot of Mount Etna, between the volcano and the Mediterranean Sea, the first winery in the region to be certified organic in 2000. The wines are produced in the Etna DOC appellation.

In the middle of a small paradise of biodiversity, rich in wild herbs, medicinal plants, olive trees and fruit trees, it grows only autochthonous grape varieties on 10 hectares in Viagrande (Contrada Blandano), between 450 and 500 meters above sea level and 2 hectares acquired in 2020 in Milo to produce the "Etna Bianco Superiore" cuvée. The grape varieties are Carricante and Catarratto in white, Nerello Mascalese and Nerello Cappuccio in red. 

Terra Constantino is a family estate with 40 years of history, but the vine has existed here around the volcano since Greek and Roman antiquity.
