Whether you think that Gavi di Gavi and Gavi, are two different wines or not, that one is better than the other, there is only one appellation, the Gavi DOCG.
Gavi, from 1998 a DOCG wine, is one of the most famous and known Italian white wines and the reason behind some of the wines being labellled Gavi di Gavi or Gavi del comune di Gavi and some Gavi lies in the vineyards locations, a Gavi di Gavi or Gavi del comune di Gavi wine simply indicated that the vineyards from which the grape comes from, are located within the borders of the town of Gavi, all other Gavi made from grapes grown within the appellation area but outside the town of Gavi are not allowed to have “di Gavi” on the label and there are good and bad wines in and outside the Gavi area.
There are several examples of Italian appellations that, despite being one, allow wine maker to have additional words on the label, “classico”, is one except for the Chianti where Classico is one of them.
Gavi DOCG is a white wine produced in the Alto Monferrato, in the southern part of the province of Alessandria, Piedmont, north east of Italy, border with Liguria and made exclusively from Cortese grapes grown in the town of Gavi and surrounding villages, from which it takes its name. Cortese is also grown and wines are made outside the DOCG area but they cannot be called Gavi.
The Gavi DOCG wine has a light straw colour with green hues and a delicate, fruity nose with apple hints. The wine is dry, fresh, full and elegant. In the last few years, wine makers have started to produce more structured and complex wines with very good results proving that the Cortese grape grown in the Gavi area is suitable for aging in bottle or barrels.
