Champagne vs Prosecco
Two sparkling wines split by where the second fermentation happens: in the bottle for Champagne under the Méthode Champenoise, and in a pressurised tank (autoclave) for Prosecco DOC spumante.
Champagne and Prosecco are both part of their countries' appellation (denomination) systems, ultimately overseen at EU level (Decanter, updated 2026). Champagne is an AOC in northern France, recognised in 1936, and Prosecco comes from the north-eastern Italian regions of Veneto and Friuli Venezia Giulia, where the Prosecco DOC was recognised in 2009 alongside two DOCGs in the hills, Conegliano Valdobbiadene and Asolo. The core difference is where the bubbles are made. Champagne's second fermentation, the prise de mousse, takes place in the bottle under the Méthode Champenoise, while the Prosecco DOC disciplinare requires spumante to be made exclusively by natural fermentation in autoclave. Decanter (updated 2026) links that difference to flavour: more autolytic bread, brioche and toast notes in some Champagnes, and the fruit of the Glera grape, associated with pear, apple, honeysuckle and floral notes, in most Prosecco.
The Comité Champagne describes the Méthode Champenoise as a primary fermentation in tanks that turns the must into wine, followed by a bottle fermentation, the prise de mousse, whose purpose is to make the wine sparkling. Decanter (updated 2026) adds that the base wine is bottled with yeast and sugars (liqueur de tirage) and left in contact with the dead yeast cells, then riddled so the sediment collects at the neck, disgorged, and topped up with liqueur d'expedition in the dosage.
The Prosecco DOC disciplinare requires Prosecco spumante to be made exclusively by natural fermentation in autoclave, and Prosecco spumante rosé by natural fermentation in autoclave over at least 60 days; Prosecco frizzante may be fermented in bottle or in autoclave. Decanter (updated 2026) describes the tank method as adding sugar and yeast to the base wine in a pressurised tank, then filtering the wine to remove the sediment before dosage and bottling. Bottle fermentation survives in the Conegliano Valdobbiadene DOCG, whose disciplinare reserves the mention 'sui lieviti' for spumante superiore fermented in bottle without separating the fermentation residues.
The Comité Champagne's grape varieties page puts Pinot Noir at 38 percent of the area under vine, Chardonnay at 31 percent and Meunier at 31 percent, while its key figures for 2025 give Pinot Noir 38, Chardonnay 32 and Meunier 30 percent. Five other varieties are authorised within the AOC, Arbane, Petit Meslier, Chardonnay Rose, Pinot Blanc and Pinot Gris, which the Comité Champagne says 'may only account for 0.3% of the area under vine'; Chardonnay Rose was listed among the authorised varieties in 2025. Rosé Champagne uses the same varieties as white, coloured either by maceration or by adding a still red Champagne wine to the base white wines before the second fermentation (Comité Champagne).
Under the Prosecco DOC disciplinare, Prosecco, Prosecco spumante and Prosecco frizzante come from Glera, with Verdiso, Bianchetta trevigiana, Perera, Glera lunga, Chardonnay, Pinot bianco, Pinot grigio and Pinot nero (vinified white) allowed alone or together up to 15 percent; Prosecco spumante rosé takes 85 to 90 percent Glera and 10 to 15 percent Pinot nero vinified red. The Conegliano Valdobbiadene DOCG disciplinare names Verdiso, Bianchetta trevigiana, Perera and Glera lunga as the varieties that may join Glera up to 15 percent. Decanter (updated 2026) notes that the variety used to be called Prosecco and was officially recognised as Glera in 2009, when the current Prosecco DOC and DOCG zones came into being.
Decanter (updated 2026) says the extended contact with the yeast in the traditional method can produce more autolytic flavours, bread, brioche and toast, in some Champagnes. The Comité Champagne gives the pressure inside a bottle of Champagne as 5 to 6 bar, about three times the pressure of a car tyre, and says the wine contains roughly 12 g of carbon dioxide per litre.
Decanter (updated 2026) says the yeast has less influence on Prosecco made by the tank method because there is no extended lees contact, and that most Prosecco is about the fruit of the Glera grape, associated with pear, apple, honeysuckle and floral notes, while some top Prosecco styles are made by the traditional method or undergo lees ageing. Decanter (2024) notes that typical spumante styles generally have at least 3 atmospheres of pressure. The Prosecco DOC disciplinare sets a minimum total alcohol of 11.00% vol for spumante and 10.50% vol for frizzante.
The Comité Champagne places the region some 90 miles east of Paris, with Reims at a latitude of 49°5 north and Épernay at 49°, and describes a dual climate with oceanic and continental influences, an average annual temperature of 11°C and vines planted at the limits of their cold tolerance. It says the vines are planted on sloping hillsides to soak up as much sunlight as possible, so that the grapes retain their natural acidity even when fully ripe.
The Prosecco DOC disciplinare describes an area in north-eastern Italy that is mainly flat with some hilly zones and has a temperate climate: the Alps shield it from cold northern currents, scirocco winds from the Adriatic bring rain especially in summer, and dry bora winds from the east at the end of summer bring wide day-night temperature swings. The Conegliano Valdobbiadene DOCG disciplinare describes elongated 'hogback' hills backed by the Prealps, 40 km from the Venice lagoon, with steep south-facing vineyards and cool air from the Prealps descending the slopes at night while the grapes ripen.
The Comité Champagne says the outcrops of sedimentary rock in Champagne are 75 percent limestone, composed of chalk, marl and limestone proper, and that porous chalk acts as a reservoir storing 300 to 400 litres of water per cubic metre. It matches varieties to soils: Chardonnay mainly in the Côte des Blancs and Côte de Sézanne, Pinot Noir in the Montagne de Reims, the eastern part of the Marne Valley and the Côte des Bar, and Meunier in the western part of the Marne Valley.
The Prosecco DOC disciplinare describes mainly alluvial soils with a dominant clay-silt texture and a good presence of stony material from the erosion of the Dolomites and from river deposits, which gives good drainage. For the Conegliano Valdobbiadene DOCG, its disciplinare says the soils originated from the uplift of sea beds, were later modified by glaciers and rivers, and are mostly sandstones and marls alternating with morainic and alluvial layers.
The Comité Champagne says the Champagne AOC was recognised in 1936 and that its production zone, whose perimeter is defined by legislation enacted in 1927, covers some 34,300 hectares and 319 villages, also called crus; its key figures for 2025 give 34,200 hectares across 5 départements and 319 villages. The Comité interprofessionnel du vin de Champagne (CIVC) was founded in 1941, and the Champagne designation is recognised and protected in more than 130 countries (Comité Champagne). Because the legislation requires the clusters to reach the pressing centre whole, Champagne is harvested fully by hand, and Champagne AOC wines may only be produced from the fruit of third-leaf vines (Comité Champagne).
The Prosecco DOC, recognised by D.M. 17 July 2009, covers the provinces of Belluno, Gorizia, Padova, Pordenone, Treviso, Trieste, Udine, Venezia and Vicenza, with a maximum yield of 18 tonnes of grapes per hectare for Glera (disciplinare). The Conegliano Valdobbiadene DOCG, which its disciplinare places within the Prosecco DOC zone and records as recognised in 2009, caps yields at 13.50 t/ha, at 13.0 t/ha for Rive wines from its 43 listed geographic units and at 12.00 t/ha for Superiore di Cartizze, a subzone of 106 ha; grapes for Superiore di Cartizze, Rive and sui lieviti must be picked by hand. The Asolo Prosecco DOCG disciplinare caps yields at 13.5 t/ha.
The Comité Champagne sets out the dosage bands by sugar per litre: brut nature under 3 g with no added sugar, brut under 12 g, extra dry 12 to 17 g, sec 17 to 32 g, demi-sec 32 to 50 g and doux over 50 g. The liqueur de dosage is cane sugar dissolved in wine, about 1 cl in a 75 cl bottle of brut, and the Comité's FAQ calls non-vintage Brut the most common Champagne.
The Prosecco DOC disciplinare allows spumante to be sold as brut nature, extra brut, brut, extra dry, dry or demi-sec, and spumante rosé as brut nature, extra brut, brut or extra dry only. The Conegliano Valdobbiadene DOCG disciplinare requires its spumante to be sold from Extra Brut to Demi-Sec, and sui lieviti wines as Brut Nature.
Under the regulations, non-vintage Champagne must age in the cellar for at least 15 months and vintage Champagne for at least 3 years from bottling, and most producers extend this by a few years (Comité Champagne). Decanter (updated 2026) puts the minimum time on the lees at 12 months for non-vintage, plus three months after disgorgement, and three years for vintage. A vintage Champagne is made solely from wines of one harvest and contains no reserve wines, while most Champagne blends different vintages (Comité Champagne).
The Prosecco DOC disciplinare lets frizzante, spumante and spumante rosé be released from 1 January of the year after the harvest, requires a spumante labelled millesimato to contain at least 85 percent wine of the stated vintage, and requires spumante rosé to carry the term millesimato with the harvest year. In the Conegliano Valdobbiadene DOCG, Rive wines may be released from 1 March of the year after the harvest, and sui lieviti wines only after at least ninety days of fermentation and time on the lees (disciplinare).
The Comité Champagne's key figures for 2025 count 266.1 million bottles shipped, 16,460 growers, 120 cooperatives and 410 houses, and put Champagne at 0.5 percent of the global area under vine, 8 percent of world consumption of sparkling wines by volume and 31 percent by value.
Decanter (2024) calls Prosecco DOC Italy's leading wine denomination in both volume and value, with more than 616 million bottles in 2023 according to the Prosecco DOC consorzio, and gives the DOC 28,000 ha across Veneto and Friuli Venezia Giulia. It places the Prosecco Superiore DOCG in a smaller area between Conegliano and Valdobbiadene in Treviso province.
The Comité Champagne places the years from 1670 to 1720 as the period when making sparkling wine became a deliberate choice in the region. On 4 July 2015 the Champagne Hillsides, Houses and Cellars were added to the UNESCO World Heritage list (Comité Champagne).
The Prosecco DOC disciplinare dates the first documents citing a Prosecco wine to the end of the 1600s, describing a delicate white wine from the Trieste Karst and the territory of Prosecco. The Conegliano Valdobbiadene DOCG disciplinare credits Francesco Maria Malvolti, in 1772, with the first written reference to Prosecco growing in those hills, and records Italy's first School of Viticulture and Oenology, founded in Conegliano in 1876, and DOC recognition in 1969. Decanter (updated 2026) notes that UNESCO listed 'Le Colline del Prosecco di Conegliano e Valdobbiadene' four years after Champagne's 2015 listing.
Choose Champagne to taste what time in bottle on the lees does: the Comité Champagne requires at least 15 months of cellar ageing for non-vintage and 3 years for vintage, and Decanter links the yeast contact of the traditional method to bread, brioche and toast notes in some Champagnes. Choose Prosecco for the fruit of the Glera grape, which Decanter associates with pear, apple, honeysuckle and floral notes, in wines the Prosecco DOC disciplinare lets producers release from 1 January of the year after the harvest. For Prosecco with lees character, look to the Conegliano Valdobbiadene DOCG's sui lieviti wines, fermented in bottle and released only after at least ninety days of fermentation and time on the lees.
