Which sparkling wine is not made in the traditional method like Champagne?

B.

Prosecco is made by the Charmat, or tank method. In this method, the second fermentation (which creates the bubbles) takes place in a large tank. By contrast, in the traditional (Champagne) method, the second fermentation takes place inside each individual bottle. There are many reasons why Prosecco is relatively inexpensive, while Champagne is relatively expensive. One of them has to do with this. It is much more painstaking and expensive to conduct the second fermentation inside individual bottles rather than giant tanks.
