The Bardolino D.O.C. outlined in 1968, it includes all or part of the municipalities of Torri del Benaco, Lazise, Bardolino, Pastrengo, Bussolengo, Castelnuovo del Garda, Sona, Peschiera del Garda, Sommacampagna and Valeggio sul Mincio.

The Superiore denomination is attributed to the wine obtained from the best grapes of particular vineyards, aged for at least a year, starting from 1 November of the year of production.
Chiaretto is obtained by vinifying the grapes in "pink", that is, with the traditional method of partial contact of the must with the skins.
The Chiaretto sparkling wine with natural fermentation methods gives Brut Sparkling Wine, the first of its kind in Italy.
