Types of Sparkling Wine: Place, Method and Sweetness
In briefSparkling wine types are easiest to understand on five separate axes. Place: protected names such as Champagne, Cava, Prosecco and Crémant d'Alsace. Method: second fermentation in the bottle (traditional), in a pressure tank (Martinotti or Charmat), a single ancestral fermentation (pét-nat), or added carbon dioxide. Grape: Chardonnay, Pinot Noir, Glera, Xarel·lo and others. Pressure: fully sparkling or gently fizzy. Sweetness: Brut Nature through Doux. Open any bottle pointed away from people, and seek medical care for an eye hit by a cork.

What are the main types of sparkling wine?

The main types of sparkling wine are best sorted on five separate axes rather than one list. Place: protected names such as Champagne, Cava, Prosecco and Crémant d'Alsace. Method: second fermentation in the bottle, in a pressurised tank, a single "ancestral" fermentation, or added carbon dioxide. Grape: Chardonnay, Glera, Xarel·lo and others. Pressure: fully sparkling or gently fizzy. Sweetness: label terms from Brut Nature to Doux. Most confusion comes from mixing those axes up.

Why do sparkling wine labels feel so confusing?

Because each word on the label answers a different question. "Prosecco" tells you where a wine comes from and, by implication, how it was made. "Brut" tells you about sugar. "Frizzante" tells you about the strength of the fizz. "Blanc de Blancs" tells you about grape colour. A shelf of sparkling wine is a shelf of answers to five different questions, printed in the same typeface.

The fix is to read each bottle one axis at a time, which is how the sections below are arranged.

Which sparkling wines are named after a place?

The most familiar sparkling wine names are protected origins: names that may only be used by wine grown and made in a defined area, under that area's written rules.

A place name does not tell you how sweet the wine is, or whether it is white or rosé. It tells you which rulebook the producer had to follow.

What is the traditional method?

The traditional method (also called the Champagne method, or méthode traditionnelle) makes the bubbles inside the bottle you eventually buy. A still base wine is bottled with a "liqueur de tirage", which the Comité Champagne defines as "a mixture of still wine, sugar and yeast". The bottle is sealed, and in the Comité's words, "The yeast will consume the sugar, releasing alcohol and effervescence, i.e. bubbles" (bottling and second fermentation).

The spent yeast, called lees, then stays in the bottle. As it breaks down, a process the Comité calls autolysis, it slowly changes the wine. Many tasters link long lees ageing with bready, brioche-like notes, which is one reason the time spent on lees matters. Each region sets a minimum time on those lees:

Wine Minimum ageing rule
Champagne (non-vintage) at least 15 months in the producer's cellars
Champagne (vintage) at least three years
Cava de Guarda 9 months minimum on lees
Cava Reserva 15 months minimum
Cava Gran Reserva 30 months minimum
Cava de Paraje Calificado 36 months minimum
Crémant d'Alsace lees ageing "which must be over nine months"

Figures from the Comité Champagne, the Cava DO and Vins d'Alsace.

These are floors, not targets. The Comité Champagne notes that non-vintage Champagne is typically aged two to three years and vintage Champagne four to ten. "Traditional method" tells you how the bubble was made; the ageing tier tells you how long the wine sat with its yeast.

What is the tank method used for Prosecco?

The tank method makes the second fermentation happen in a large sealed pressure tank instead of in each bottle. In Italy it is called the Martinotti method; elsewhere it is often called the Charmat method. The Prosecco DOC consortium explains that the wine "is held in big tanks called autoclave", where the second fermentation must "last at least 30 days" for Frizzante and Spumante and at least 60 days for Rosé (Prosecco DOC winemaking).

Prosecco Spumante "shall be obtained exclusively through natural autoclave fermentation", while Frizzante may be made by "natural in-bottle or autoclave fermentation" (production regulation). As a general tendency rather than a rule, the shorter contact with yeast keeps the emphasis on fresh fruit.

What is the ancestral method, and what is pét-nat?

The ancestral method uses one fermentation instead of two. The wine is bottled before its first fermentation has finished, and the yeast completes the job in the bottle, trapping the carbon dioxide. Pét-nat, short for pétillant naturel, is a style made this way. Wine Spectator's glossary describes pét-nat as made without a sugar addition, usually left with its sediment in the bottle, often closed with a crown cap, sometimes cloudy and typically less fizzy than other sparkling wines.

Is carbonated wine a type of sparkling wine?

Legally, it is kept in a separate box. US federal labelling rules define sparkling grape wine as wine made effervescent with carbon dioxide that comes from fermentation "within a closed container, tank or bottle", and give a different class, carbonated grape wine, to wine whose carbon dioxide comes from any other source (27 CFR 4.21, via Cornell LII). EU rules draw a similar line with "aerated sparkling wine": wine without a protected designation of origin or protected geographical indication whose carbon dioxide has been wholly or partly added (Regulation 1308/2013, Annex VII). If a label says "carbonated" or "aerated", the bubbles were added, not fermented.

Which grapes are used to make sparkling wine?

Each protected name fixes its grapes differently:

Blanc de Blancs (white wine from white grapes only) and Blanc de Noirs (white wine from black-skinned grapes) belong on this axis too; neither says anything about sweetness or method.

How fizzy is sparkling wine?

Pressure, measured in bar, is the axis you feel on the tongue. Under the EU's wine market regulation, sparkling wine must have an excess pressure of at least 3 bar when kept at 20 °C in a closed container, quality sparkling wine at least 3.5 bar, and semi-sparkling wine between 1 and 2.5 bar (Regulation 1308/2013, Annex VII). Champagne sits well above that floor: the Comité Champagne puts it "within the range of 5 to 6 bar", which it compares to "about three times the pressure of a car tyre" (FAQ).

The gentler end has its own vocabulary. US rules describe crackling, petillant or frizzante wine as less effervescent than champagne, giving a slow, steady stream of bubbles when poured (27 CFR 4.21). Prosecco shows the split within a single name: Spumante has "a fine and persistent perlage", Frizzante "a light and less persistent perlage" (Prosecco DOC types).

How do you read sweetness on a sparkling wine label?

Sweetness is set mostly by the dosage: the small addition, just before corking, of what the Comité Champagne calls "a mixture of cane sugar dissolved in wine", typically "approximately 1cl for a 75cl bottle for a Champagne brut" (dosage). The label term tells you how much sugar ended up in the wine. Champagne's figures, in grams per litre:

Label term Sugar (g/L)
Brut Nature / Pas Dosé / Dosage Zéro less than 3
Extra Brut 0 to 6
Brut less than 12
Extra Dry 12 to 17
Sec 17 to 32
Demi-sec 32 to 50
Doux more than 50

The Brut Nature and Extra Brut rows come from the Comité Champagne FAQ; the rest from its dosage page. Prosecco DOC lists the same terms on its types page, from Brut Nature (0 to 3 g/l) to Demi-sec (32 to 50 g/l). The trap is in the middle of the table: Extra Dry sits above Brut, so an Extra Dry is the sweeter bottle.

How do you compare two sparkling wines accurately?

Run both labels through the five axes. Take a Cava Reserva Brut and a Prosecco DOC Extra Dry.

Seen that way, they are not two versions of "fizz" at different prices. They are different wines that happen to share a cork. Our guide to how to taste wine has a tasting-note format that keeps those differences on paper rather than in memory.

How should a sparkling wine bottle be opened?

A sparkling wine bottle is under pressure, and a released cork can cause a serious eye injury. Follow the steps in order. The American Academy of Ophthalmology advises: "always chill your Champagne in the fridge or on ice", do not shake the bottle, "hold the bottle at a 45 degree angle" and "point it away from yourself and any bystanders", place a towel over the top and grasp the cork, then "Slowly and firmly twist the base of the bottle while holding the cork firmly" (AAO). The Comité Champagne gives a similar sequence, with the bottle tilted to 30-45 degrees, and says to ease the cork out "without letting it pop out" (FAQ). If anyone is hit in the eye, the AAO's instruction is to "seek medical care right away."

For target serving temperatures, see how cold wine should be; for how long an opened bottle keeps its sparkle, see how long wine lasts after opening. Sparkling wine is for adults of legal drinking age, and a glass of fizz carries the same alcohol considerations as any other wine.

Questions

What is the difference between Champagne, Prosecco and Cava?

They differ on almost every axis. Champagne comes from France's Champagne region, is made mainly from Pinot Noir, Meunier and Chardonnay, and gets its bubbles from a second fermentation in the bottle, with at least 15 months of cellar ageing for non-vintage wine. Cava is Spain's bottle-fermented sparkling wine, usually from Macabeo, Xarel·lo and Parellada, aged at least 9 months on lees. Prosecco DOC is Italian, made mainly from Glera, with its second fermentation in pressure tanks.

Is Extra Dry sparkling wine sweeter than Brut?

Yes. On sparkling wine labels, Extra Dry is the sweeter of the two. The Comité Champagne defines Brut as less than 12 grams of sugar per litre and Extra Dry as 12 to 17 grams per litre, and Prosecco DOC uses the same terms. The driest labels are Brut Nature, also called Pas Dosé or Dosage Zéro, at under 3 grams per litre, and Extra Brut at 0 to 6 grams per litre.

What does traditional method mean on a sparkling wine label?

Traditional method means the bubbles were made inside the bottle you buy. A still base wine is bottled with a mixture of wine, sugar and yeast, the bottle is sealed, and the yeast turns the sugar into alcohol and carbon dioxide. The spent yeast stays in the bottle for a minimum period set by each region: at least 15 months for non-vintage Champagne, 9 months for Cava and more than nine months for Crémant d'Alsace.

What is the difference between spumante and frizzante?

The difference is pressure, which you notice as the strength of the fizz. The Prosecco DOC consortium describes Spumante as having a fine and persistent perlage, or stream of bubbles, and Frizzante a light and less persistent one. Under EU rules, sparkling wine must reach at least 3 bar of pressure at 20 °C, while semi-sparkling wine sits between 1 and 2.5 bar. Prosecco Spumante must be tank-fermented; Frizzante may be tank- or bottle-fermented.
