Key figures

Region Conegliano Valdobbiadene, Veneto — UNESCO World Heritage Site since 2019

Rule change Sub-zone (Rive) designation now requires minimum 85% estate-grown fruit

New requirement Vintage year mandatory on all Rive-labelled bottles from 2027 harvest

Superiore di Cartizze The 107-hectare single-hill DOCG cru — no change to existing rules

Context Prosecco DOC (broader, lower-tier category) produced 600 million bottles in 2025

What the revision changes

The Consorzio Prosecco DOC and the Italian agricultural ministry (MIPAAF) have approved amendments to the Conegliano Valdobbiadene Prosecco Superiore DOCG production rules, effective from the 2027 harvest. The two main changes concern the Rive sub-zone designation: bottles labelled with a specific Rive must now be made from a minimum of 85% estate-grown (from the named Rive) fruit rather than sourced from multiple growers, and must carry a vintage year. Both requirements were already encouraged but not legally mandated.

The motive is differentiation from the mass market. Prosecco DOC — the broad commercial category — produced approximately 600 million bottles in 2025 at prices as low as £6–7 at retail. The DOCG's hill vineyards, which must be harvested by hand on steep gradients and represent a fraction of total Prosecco production, need a clearer identity to justify their 3–5x price premium over DOC. Tighter provenance rules are the standard mechanism for this — the same logic that drove Burgundy's MGA formalisation (see the Italian DOC reform article).

Cartizze: the unchanged apex

Superiore di Cartizze — a single hill of 107 hectares within the DOCG between the villages of San Pietro di Barbozza, Santo Stefano and Saccol — remains unchanged and is already the most tightly regulated tier. Cartizze produces roughly 1.5 million bottles annually from approximately 140 owners. Its unique microclimate (fog, morning dew) creates a wine with more weight, longer finish and subtle complexity compared to standard DOCG. Cartizze is effectively Prosecco's equivalent of a Burgundy Grand Cru in geographic designation, though the winemaking method remains the same charmat process.

Questions

About Prosecco and its classifications.

What is the difference between Prosecco DOC and Prosecco DOCG?

Prosecco DOC covers a wide swath of northeastern Italy including parts of Friuli — it is the broad commercial category producing the majority of Prosecco sold globally. Prosecco DOCG (specifically Conegliano Valdobbiadene Prosecco Superiore DOCG) is restricted to a smaller, hilly zone between the towns of Conegliano and Valdobbiadene in the Veneto. The DOCG vineyards, recognised as a UNESCO World Heritage Site in 2019, are steep and must be harvested by hand — the resulting wines are considered more complex and site-expressive than the broader DOC. For how Italian classification tiers work, see the Italian DOC/IGT reform article.

What is a Rive in Prosecco DOCG?

Rive (singular: riva, meaning "hillside" in local dialect) are the 43 officially recognised sub-zones within the Conegliano Valdobbiadene DOCG. Each Rive corresponds to a specific village or hamlet and its surrounding steep hillside vineyards. A Prosecco labelled with a specific Rive name (e.g., "Rive di Ogliano" or "Rive di Col San Martino") must come entirely from that sub-zone, be vintage-dated and be made by the charmat (tank) method. The Rive system gives Prosecco DOCG a terroir-focused hierarchy similar to Burgundy's village designations.

How is Prosecco made — is it the same method as Champagne?

No. Most Prosecco is made by the Charmat method (also called Martinotti or tank method): the base wine undergoes its second fermentation in a pressurised stainless steel tank, then is filtered and bottled under pressure. Champagne and high-quality English sparkling wine use the traditional method (méthode champenoise): second fermentation happens inside the individual bottle, with extended lees ageing before disgorgement. The tank method is faster and less expensive; it produces lighter, fruitier, lower-autolytic character (less brioche and toast, more fresh apple and peach). A small number of Prosecco producers make Col Fondo (traditional method, unfiltered) as a premium alternative. See the Red, white, rosé and sparkling methods guide.

What grape variety is Prosecco made from?

The primary variety is Glera (historically called Prosecco, but EU rules renamed the variety to Glera in 2009 to protect the place name). Glera accounts for a minimum 85% of the blend in all Prosecco DOC and DOCG wines. Up to 15% can be made from permitted local varieties including Verdiso, Bianchetta Trevigiana, Perera and Glera Lunga. Glera is a neutral grape with moderate acidity, producing light wines with apple, pear, white peach and light floral notes — well suited to the fresh, early-drinking Prosecco style.

Why does Prosecco outsell Champagne globally?

Price and accessibility. Entry-level Prosecco DOC retails at £7–10 in the UK, compared to £30–35 for non-vintage Champagne. Prosecco's lighter, fresher, lower-alcohol style (typically 11–11.5% ABV vs 12–12.5% for Champagne) also suits casual drinking occasions. Production volumes are vastly larger — 600 million Prosecco bottles vs approximately 320 million Champagne bottles in 2025. The categories are not truly in competition: Champagne leads in prestige occasions; Prosecco leads in aperitivo, casual entertaining and price-sensitive retail.
