It is thought that the cultivation of vine and winemaking were brought to western Sicily by the Phoenicians between the 8th and 7th centuries B.C. although the discovery of organic residues detected in some of the copper age at the prehistoric sites of Mount Kronio (Sciacca) and Sant' Ippolito (Caltagirone) has led to the view of the production of wine in Sicily among the oldest attics in the world dating back to at least 6000 years ago.
