Which statement about bubble characteristics is associated with the Charmat method?

• A. Finer, longer-lasting bubbles
• B. Larger, quicker-forming bubbles
• C. No bubbles
• D. Highly persistent bubbles with mousse

Answer: (B)

In the Charmat tank method, the secondary fermentation happens in large sealed tanks under pressure, not in individual bottles. This setup leads to CO2 being formed and dissolved quickly in the wine, so when the wine is released, bubbles form rapidly and tend to be larger as they nucleate and rise. That’s why this approach is associated with larger, quicker-forming bubbles.

Think of it as contrast to the traditional bottle-fermented method, which develops finer bubbles over a longer time and with more persistent mousse. The other options don’t fit the tank-based process—there aren’t no bubbles, and bubbles aren’t typically highly persistent from this method.
