 Chestnuts are the main ingredient in the making of "pulenta".A variety of alcoholic drinks also exist, ranging from "aquavita" (brandy), red and white Corsican wines ("Vinu Corsu"), muscat (plain or sparkling), and the famous "cap corse" produced by Mattei.Genetic research has revelead that the Corsican samples presented affinities with people from Provence (France) and the Italians from Liguria, Campania, Sicily and Latium; other genetic studies pointed to a regional differentiation along a North-South axis, mirroring the island's geographic and linguistic features.
