The Falerio production zone, as defined by the DOC discipline, includes virtually the whole of the grape-growing area of the province of Ascoli Piceno. It extends from the foothills of the Apennines to the Adriatic coast. Only the Rosso Piceno vineyards in the eastern part of the area are excluded.
Like the Falerio dei Colli Ascolini itself, Passerina and Pecorino, two of the varieties used in making it along with Trebbiano, Malvasia, Verdicchio and Pinot Bianco, boast extensive pedigrees. They are varieties of an extremely ancient tradition. Both clearly originated in the Marches, although the Pecorino has spread into neighboring Umbria. And both have strong personalities in terms of flavor that have made them indispensable ingredients of the Falerio and Rosso Piceno wines.
