How To Keep Open Champagne Bubbly On New Year's Eve Without A Stopper - Tasting Table
Briefly

To keep champagne bubbly at a New Year's celebration, it's essential to maintain its chilled temperature and use glasses that promote bubble retention.
The biggest culprit for champagne going flat is the release of carbon dioxide after the bottle is opened; maintaining low temperatures can slow this process.
Etched glassware plays a critical role in preserving the champagne’s effervescence, as the microscopic bubbles adhere to the etched patterns, creating a more vibrant fizz.
Utilizing an ice bucket or chest keeps champagne cold effectively, and ensuring the glasses are proper can enhance the overall experience by maintaining the bubbly.
