COS is perhaps the most celebrated producer in the Vittoria region of southeastern Sicily, which is home to Sicily’s lone “DOCG” designation: Cerasuolo di Vittoria. Wines labeled “Cerasuolo di Vittoria” combine the Syrah-like Nero d’Avola with the racy, featherweight, strawberry scented Frappato, usually in 60%-40% proportions. Because of the “di” in the name, some consumers might be tempted to think of Cerasuolo as a grape name (as in the Cerasuolo grape “of” Vittoria, like Barbera d’Asti or Sangiovese di Romagna), but in this case it refers to the style (“cherry-like”) of the wine produced. Vittoria is the anchor town in the zone, where the soils are referred to as terra rosa: reddish, sandy clays with a strata of limestone underneath.
