There are 10 D.O.C.G. wines in the Piedmont and about 40 with D.O.C. designation.
D.O.C. - Denominazione di Origine Controllata - M
eans that the wine is made from grapes grown in a recognized and unique wine growing zone.
D.O.C.G. - Denominazione di Origine Controllata e Garantita - The
"G" means that the quantity of wine production is controlled. Ever notice those pink labels wrapped around the neck of a bottle, they hand those out to wineries based on the acreage (hectars) of grapes grown.
The best source of information on the local wines for a particular area is the Enoteca Regionale of the region where you are going. Remember the D.O.C/D.O.C.G. name does not necessarily tell you the name of the grape, but the name of where the wine was grown. Think Barbaresco and Barolo... both are made with 100% Nebbiolo grapes but because they are grown in different areas (only 12 km apart), the wine that is produced from each region is truly unique enough to have its own name.
