Final answer:
Wines from the Champagne appellation are typically matured and commercialized in the same bottle where the second fermentation occurs. However, there are exceptions to this rule such as large formats and transversal aging.
Step-by-step explanation:
Wines from the Champagne appellation are required to be matured and commercialized in the same bottle where the second fermentation took place to create the bubbles.
However, there are a few exceptions to this rule.
Large Formats:
Some exceptions include large formats such as magnums (1.5 liters), jeroboams (3 liters), and methuselahs (6 liters).
These larger bottles are allowed to be matured in the bottle where the second fermentation occurred but can be transferred to smaller bottles for commercialization.
Transversal Aging:
Another exception is transversal aging, where the wine is aged on its lees (dead yeast) in the same bottle where the second fermentation took place for a certain period of time.
Afterward, the wine is transferred to a different bottle for commercialization.
