The Colli Pesaresi wines are produced in the hills overlooking the city of Pesaro in an area consisting of the territories of 33 communes. The zone extends from the border with the Romagna along the hills sealing in the rivers Foglia, Metauro and Cesano as far as Monte Ardizio outside Fano.
Recently, a dispute opposed the growers of the Marches to those of the Romagna over the origins of the Sangiovese . The Romagna growers argued that the wine of the Colli Pesaresi could not be recognized as a DOC product because they alone were entitled to use the name of the Sangiovese variety. The Pesaro growers won the battle in 1972, after they demonstrated that Sangiovese had been cultivated in their area for centuries. They also argued that the variety was Tuscan in origin.
