The Prosecco DOC production area covers the northeast Italian territories of Treviso, Venice, Vicenza, Padua and Belluno in the Veneto; and Gorizia, Pordenone, Trieste and Udine in Friuli Venezia Giulia.
Prosecco DOC totals approximately 20,000 hectares.
Prosecco Conegliano Valdobbiadene Superiore DOCG covers the Treviso province of Veneto, on the hills between the towns of Conegliano and Valdobbiadene, while there is also the smaller Asolo Prosecco Superiore DOCG, produced near the town of Asolo.
Prosecco DOCG totals approximately 6,600ha.
Superiore di Cartizze is a hill within the Conegliano Valdobbiadene DOCG that is famous for producing the most concentrated expression of Prosecco – and often the sweetest. It covers 107ha and is home to the most expensive vineyard land in Italy, with an estimated value of €1.5m-€2m (£1.32m-£1.76m) per hectare.
While Cartizze is at the top of the Prosecco Superiore DOCG quality pyramid, the Consorzio recently introduced the Rive delimitations, which are named after particular sub-zones with distinct and high-quality terroirs.
The majority of Prosecco is sold as ‘Extra Dry’, meaning it contains 12-17g/l of residual sugar. Lower than that is sold as ‘Brut’, and higher is labelled ‘Dry’ (17-32g/l).
