It is produced in Tuscany, in strictly delimited areas among the provinces of Florence, Siena and Grosseto. It is based mainly on Sangiovese grapes but also includes other varieties. Chianti is a DOC, but corresponds to a much larger area than the region originally known as Chianti. Wine from this smaller region is labelled Chianti Classico and is a DOCG. It typically has a picture of a black rooster (known in Italian as a gallo nero) on the neck of the bottle. Chianti Classico that meets slightly more stringent requirements, primarily with respect to aging, may be labelled Chianti Classico Riserva.
