Lombardy's most prized wines are undeniably their metodo classico sparkling wines of Franciacorta, which have attained the status of DOCG (while the red and white wines of the zone come under the Terre di Franciacorta DOC. The Terre di Franciacorta DOC applies to sturdy reds made from Cabernet, Barbera and Nebbiolo, as well as to white wines from Pinot Bianco and Chardonnay. However Franciacorta's reputation has been built on the outstanding bottle-fermented sparkling wines fashioned by estates. Nearly a third of Italy's bottle-fermented sparkling wine is produced in the Brescia area, but only wines from select vineyards in the zone qualify as Franciacorta DOCG.
