Number of DOCG (Denominazione di Origine Controllata e Garantita) regions in Italy as of July 2017. Established in 1963, DOCG is the highest category of “controlled and guaranteed” wine designations in Italy. Barolo, Barbaresco, and Brunello di Montalcino were among the first regions to achieve the title. Nizza in Piedmont (which makes red wine from barbera grapes) was the latest. It became a DOCG in 2014.
