The quick answer
Sparkling wine contains dissolved carbon dioxide created during fermentation. Champagne, Prosecco, Cava, and other sparkling wines differ in grapes, origin, production method, sweetness, and time spent aging—not simply in price.
Traditional method versus tank method
In the traditional method, the fermentation that creates bubbles happens in each bottle. Time resting on yeast sediment can add bread, pastry, or nutty flavors. In the tank method, that fermentation happens in a sealed vessel, which tends to preserve fresh fruit and floral aromas.
- Champagne: protected French origin; often citrus, chalk, and brioche
- Prosecco: usually fruit-forward, floral, and softly sparkling
- Cava: Spanish traditional-method sparkling wine
- Sparkling rosé: a color and style category, not one grape
Decode sweetness words
Brut usually signals a dry-tasting style, while extra dry is confusingly a little sweeter than brut. Demi-sec is noticeably sweet. Acidity and bubbles can make the same sugar level feel less sweet, so the label is a guide rather than a complete sensory prediction.
Chill and open safely
Serve sparkling wine well chilled and point the bottle away from people and fragile objects. Hold the cork while turning the bottle slowly; aim for a quiet sigh instead of a dramatic pop. A tulip-shaped glass preserves bubbles while leaving room for aroma.
