Prosecco DOC vs DOCG: two wines under one name

One name, two zones — and a village near Trieste

The 2009 reform that created Prosecco DOC did something unusual: it anchored the wine's name to the village of Prosecco, near Trieste, turning what had been a grape name into a protected place name. That legal move is why the DOC zone stretches across 627 municipalities in two regions — from the Friulian border all the way through Veneto — and why growers outside it cannot legally write "Prosecco" on a bottle, even with identical grapes. It is the largest production zone of any Italian denomination bar a handful of food IGPs, and the reason the word on the shelf tells you so little until you read the next line of the label.

The DOCG heartland: 15 municipalities of near-vertical vineyards

Conegliano Valdobbiadene Prosecco Superiore DOCG is the opposite proposition: 15 municipalities of steep hills between the towns of Conegliano and Valdobbiadene, a zone first recognised in 1973 and promoted to DOCG when the broad DOC was created around it. The slopes are so abrupt that most work is done by hand — the disciplinare's Rive category makes hand harvesting mandatory. In 2019 UNESCO inscribed these hills, Le Colline del Prosecco, on the World Heritage list. Today 276 verified producers are on the consortium's official list, against zones elsewhere where a single cooperative can bottle the output of hundreds of growers.

Same grape, tighter numbers

Both wines are built on Glera, minimum 85%, with local varieties like Verdiso, Bianchetta Trevigiana and Perera allowed up to 15%. The differences are in the ceilings. The DOCG caps yields at 13.5 tonnes per hectare for the base wine, dropping to 13 for Rive and 12 for Superiore di Cartizze, the small celebrated hill inside Valdobbiadene. Minimum alcohol climbs from 10.5% for the base tipologia to 11.5% for Rive and Cartizze. The 'sui lieviti' style — bottle-refermented, at least 90 days on the lees, Brut Nature only — is the disciplinare's nod to the farmhouse Prosecco that predates tank fermentation.

Rive and Cartizze: reading the small print

Two words on a DOCG label reward attention. Rive — dialect for steep slope — followed by a village name means every grape came from that single named hillside, hand-picked, at reduced yield: the closest Prosecco gets to a Burgundian cru system, with dozens of Rive each bottling its own exposure. Superiore di Cartizze goes further: one famous hill, the strictest yields of the whole denomination. Both mentions exist only in the DOCG — a bottle of broad-zone Prosecco DOC can never carry them, which makes them the fastest way to tell the hillside wine from the plain one without turning the bottle around.

Also on the shelf: Asolo

A third denomination completes the picture: Asolo Prosecco DOCG, on the other bank of the Piave river — 18 municipalities around the hill town of Asolo, with 74 producers on the consortium list. Smaller and less famous than Conegliano Valdobbiadene, it shares the DOCG's hillside logic and often undercuts it in price. The practical shelf rule that follows from all this: 'Prosecco DOC' tells you the country and the grape; 'Asolo' or 'Conegliano Valdobbiadene' on the label tells you the hill. Every one of these zones — all 627 municipalities of the DOC included — is drawn on ItalyTasteMap's map, boundary by boundary.
