Which statement correctly matches the function of cork and muselet?

• A. Cork decorates neck; muselet stores sugar
• B. Cork vents gas; muselet colors wine
• C. Cork is decorative; muselet optional
• D. Cork seals; muselet holds cork in place

Answer: (D)

In sparkling wine bottles, the essential function is to keep the carbonation safely inside. The cork acts as a seal, expanding to fill the neck and form a tight barrier that holds the pressurized CO2 in the liquid. The muselet is the wire cage that goes around the cork, providing the necessary support to keep the cork in place and prevent it from being forced out by the pressure as the bottle is handled or opened. That combination—cork sealing in the pressure and the muselet securing the cork—is why the statement that cork seals and muselet holds the cork in place is the correct description. Cork isn’t decorative, and the muselet isn’t used to color the wine or to be optional in standard Sparkling wine bottles.
