Which statement best describes the difference between Prosecco and Champagne fermentation methods?

• A. Prosecco uses bottle fermentation; Champagne uses Charmat
• B. Prosecco uses the Charmat Method in a tank, while Champagne ferments in the bottle.
• C. Both use same method
• D. Prosecco uses oak aging

Answer: (B)

The key idea is how the second fermentation is carried out and how that shapes the wine’s character. Champagne is made using the traditional method, with a second fermentation that happens in the bottle. This traps CO2 inside the bottle and, with aging on its lees, develops fine, persistent bubbles and more complex, toasty flavors. Prosecco, on the other hand, uses the Charmat method, where the second fermentation takes place in a sealed tank and the wine is bottled under pressure after fermentation. This tends to produce fresher, fruitier flavors with lighter, larger bubbles and less yeast-derived character. So the statement that Prosecco uses bottle fermentation and Champagne uses Charmat describes the opposite of the real process, which is why the correct description is that Prosecco is Charmat in a tank and Champagne is bottle-fermented.
