All sparkling wine is wine with bubbles. The bubbles come from a second fermentation: yeast eats sugar and makes CO₂, which gets trapped under pressure instead of escaping. Region, grapes, and price are all variations on two questions. Where did the second fermentation happen, and how long did the wine sit on the dead yeast afterwards?

The two methods that matter
Méthode champenoise (traditional method)
Also called método tradicional. The second fermentation happens inside the bottle you eventually buy: a little sugar and yeast (the liqueur de tirage) goes into the still base wine, the bottle is sealed, and the CO₂ has nowhere to go.
The yeast dies and sits in the bottle for months or years. That's lees aging, and it's where the bread-dough and biscuit notes come from. Pressure reaches around 6 atmospheres, roughly three times your car tire. The dead yeast is coaxed into the neck (riddling) and frozen out (disgorgement), then a small dose of wine and sugar (dosage) sets the final sweetness.
It's slow and expensive. Champagne, Crémant, Cava, English sparkling, and most American premium sparkling use it.
Charmat (tank) method
The second fermentation happens in a big pressurized steel tank, and the wine is bottled under pressure. Most Charmat wines get weeks on lees, not years, so fruit leads. Pressure is typically lower (sparkling Prosecco's legal floor is 3.5 bar), so the bubbles feel softer. Prosecco, most Lambrusco, most German Sekt, and most cheap supermarket sparkling are made this way.
Pick by mouthfeel, not just price. A well-made $15 Prosecco beats a sad $25 Champagne on a sunny afternoon. A $25 Cava beats a $20 Prosecco at dinner.
Champagne
Sparkling wine from the Champagne region of northeast France, made by the traditional method from Chardonnay, Pinot Noir, and Pinot Meunier (a handful of obscure others are legal but rare). The region itself is in Wine Regions Decoded.
Dryness, driest to sweetest:
Brut Nature / Zero Dosage: no sugar at dosage. Polarizing.
Extra Brut: very dry. Common in grower bottles.
Brut: the standard, and most of what you'll see.
Extra Sec / Extra Dry: off-dry, despite the name.
Sec: noticeably sweet.
Demi-Sec: dessert-wine sweet.
Doux: very sweet. Almost extinct.
No dryness term? Assume Brut.
Non-vintage (NV) is the house blend across several years, built so March's bottle tastes like November's. It's most Champagne sold. Vintage is a single declared year, made only when conditions are exceptional, with longer minimum aging (3 years vs 15 months for NV) and a much higher price. Worth it for a special bottle. Not for a Tuesday.
The back-label code is two letters near the bottom. NM (Négociant-Manipulant) is a large house buying grapes from many growers: the famous names, consistent and reliable. RM (Récoltant-Manipulant) is a grower who also makes the wine: smaller, more individual, and often better for the money. CM, RC, and ND are co-ops and miscellany. If you want Champagne that tastes like a place rather than a brand, buy RM.
Style codes:
Blanc de Blancs: white grapes only (Chardonnay, in Champagne). Lighter and sharper, the aperitif Champagne.
Blanc de Noirs: black grapes only (Pinot Noir and/or Pinot Meunier). Fuller, more red-fruit weight, better with food.
Rosé: a little red wine blended in, or short skin contact. More structured than still rosé, and surprisingly good with salmon and duck.
Crémant
French traditional-method sparkling from outside Champagne: Crémant d'Alsace, de Loire, de Bourgogne, and several others. Grapes vary by region (often Chenin Blanc, Pinot Blanc, or Riesling), and minimum lees aging is shorter. Same method, no postcode premium: a $20 Crémant is often a better wine than a $35 entry-level Champagne. When Champagne feels too expensive and Prosecco too casual, this is the answer.
Cava
Spain's traditional-method sparkling, mostly from Penedès in Catalonia. The local grapes are Macabeo, Xarel·lo, and Parellada, with Chardonnay and Pinot Noir increasingly allowed and used. The "cheap Champagne" putdown is fair at the bargain end; the high end is serious and underpriced. Cava tends to taste more rustic than Champagne: earthier, less brioche, more bitter almond.
The top tier, Cava de Paraje Calificado, is single-vineyard, with 36+ months on lees, and certified organic from the 2025 harvest. Champagne quality for half the money.
Prosecco
Glera from Italy's Veneto, made by Charmat. Drink it within 2 to 3 years of the vintage. Aged Prosecco isn't a thing.
On the label:
Prosecco DOC: the broad zone. Mass production. Fine, generic.
Prosecco DOCG (Conegliano-Valdobbiadene or Asolo): the historic hill zones. Smaller plots, hand-harvested, more character. Worth the few extra dollars.
Rive and Cartizze: single-hill and single-cru bottlings within DOCG. The good stuff.
No DOCG on the label means you're buying volume, not quality.
English sparkling
The newest serious player. In 1988 Nyetimber, in West Sussex, became the first English estate to plant the three Champagne grapes purely for sparkling wine. Its first release, a 1992 Blanc de Blancs, took gold at the International Wine and Spirit Competition. Climate change has helped southern England (particularly Sussex, Hampshire, and Kent) grow Chardonnay and Pinot Noir on chalky soils that echo Champagne. It's lean, often with a chalky mineral edge that makes blind tasters call it Champagne. Production is small, but try one to recalibrate what you think Champagne uniquely does.
American méthode champenoise
Chardonnay and Pinot Noir from California (Carneros, Anderson Valley) and Oregon (Willamette), often from producers with technical roots in Champagne. The fruit is riper (California sun does what it does), but the frame is identical. The best make sense at $30 to $50, where Champagne is just getting started.
Lambrusco
Sparkling red from Emilia-Romagna, Italy, mostly tank-made. The sweet 1970s supermarket version wrecked its reputation. The real thing is dry (secco), low in alcohol, and built for food. Slightly chilled, next to a charcuterie board, it does things no white sparkling can.
Pét-Nat
Pétillant Naturel gets no added yeast, no dosage, no riddling. It's often unfiltered, unfined, and capped rather than corked. Some are great. Some are cidery, oxidized, or actively flawed. Treat it as its own category, not a Champagne substitute. It's not always a finished, polished wine, so buy from a shop you trust.
When to buy what
Party, brunch, big group: Cava or Prosecco, $12 to $18. It'll get mixed with juice anyway.
French 75 or Champagne Cocktail: Cava or grower Champagne. Cocktails muffle a prestige bottle's lees detail.
A celebration, sipped on its own: Champagne, English sparkling, top-tier Cava de Paraje, or American premium méthode champenoise.
Seafood, oysters, fried food: Brut Champagne, Cava, or English sparkling. Acid plus bubbles cut richness. More in Food Pairing: What to Drink With What.
Sparkling that drinks like wine, not like Champagne: Crémant de Loire (Chenin) or Crémant d'Alsace (Pinot Blanc, Riesling).
Storage and serving
Serve at 43-48°F / 6-9°C. Colder mutes the aromatics; warmer, and the bubbles fade before the second sip. That's an hour in the fridge from room temp, or 20 minutes in an ice-water bath.
Open it quietly. Hold the cork, twist the bottle (not the cork), aim away from people and light fixtures. Sigh, not pop.
An open bottle keeps about 24 to 48 hours in the fridge with a proper sparkling-wine stopper. Without one, it's flat by morning.
Use a tulip or a white-wine glass: roomy enough to smell, narrow enough at the rim to hold bubbles. Flute vs coupe is in Glassware Decoded.
