Why You Shouldn't Actually Remove The Cage On Sparkling Wine - Tasting Table
Briefly

Opening sparkling wine can be daunting due to the pressure inside the bottle. Master sommelier Aldo Sohm suggests a technique for safely removing the cork: leave the cage on while untwisting the wire lock to gain better traction. This method prevents slipping and helps maintain the wine's bubbles by reducing the risk of an agitated pop. Thus, correctly opening the bottle not only enhances your grip but also preserves the integrity of the sparkling wine's effervescence for a better experience.
When opening sparkling wine, leaving the cage on the cork provides optimal grip, making it easier to twist while helping prevent spills.
By removing the cork gently, carbon dioxide remains stable, conserving the best part of the wine—its delightful bubbles.
