How do Champagne bubbles differ from those in Prosecco?

• A. Champagne has smaller, finer bubbles and a more elegant texture.
• B. Champagne has larger bubbles making it more vibrant
• C. Prosecco has smaller bubbles
• D. Champagne has no bubbles

Answer: (A)

The key idea is that bubble size and texture come from how the wine is carbonated and how long it spends aging with the lees. Champagne undergoes secondary fermentation in the bottle, under high pressure, with many nucleation points that create a crowd of tiny bubbles. Aging on the lees adds body and a creamy mousse, so the bubbles feel finer and linger longer, giving an elegant texture.

Prosecco, on the other hand, is usually made with the Charmat method in a large tank, where CO2 is dissolved under gentler, shorter fermentation conditions. This tends to produce larger bubbles that rise more quickly and don’t persist as long, resulting in a livelier, crisper effervescence but a less creamy mouthfeel.

So the champagne bubble profile—smaller, finer bubbles with a refined, silky texture—is best explained by the bottle-fermented method, higher pressure, and lees aging, compared to Prosecco’s tank-fermented, coarser bubbles.
