The most famous Italian bubbles abroad - and also the most sold ones - are produced in Veneto and Friuli-Venezia Giulia. The designations that enhance them are three, each with its own characteristics, but all based on Glera grapes and on the autoclave production method (also called Martinotti-Charmat method).

Prosecco DOC is the largest ever, being distributed over two regions. It includes two sub-zones, one in the province of Treviso and the other in the province of Trieste (the wine is called respectively Prosecco Treviso DOC and Prosecco Trieste DOC).

Conegliano Valdobbiadene Prosecco Superiore DOCG identifies a large area in the north of the province of Treviso. Inside it we can find Cartizze sub-zone, whose vineyards surround the village of San Pietro di Barbozza in Valdobbiadene municipality, known for the great quality of its wines. The word “Superiore”, contained in the designation name, indicates the typology “sparkling” to distinguish it from the less known “still” wine.

Asolo Prosecco Superiore DOCG, also known as Colli Asolani Prosecco Superiore DOCG, is another important designation of the province of Treviso. Also in this case, the word “Superiore” indicates the typology “spumante” to distinguish it from the less known still wine.
