Vittoria (Ragusa) Did you know that COS stands for the initials of the names of the company's three founders? They are Titta Cilia, Giusto Occhipinti, Cirino Strano and they gave birth to COS in 1980. The three inherited (rented) the old family cellar of Giuseppe Cilia, Titta's father and vineyard . In these 30 years of experience they have revolutionised Cerasuolo di Vittoria. They profess the Biodionamic "faith" and minimum intervention in the vineyard. Their use of Spanish amphorae, purchased 20 years ago, is also very interesting.
