Coravin Sparkling Wine Preservation System allows you to open a bottle of bubbly one weekend, then finish it at brunch the next. Whether it’s a pre-dinner glass, celebrating the end of a long day, or kicking off the weekend, Coravin lets you pop any bottle of sparkling wine without hesitation. The Coravin Sparkling Sparkling Wine Preservation System preserves the crisp flavor and effervescence up to 4 weeks, guaranteeing that the last glass will taste just as amazing as the first.The included Coravin's Sparkling Stopper adjusts to fit any standard or magnum bottle and locks securely in place. It works with the Sparkling Chargers to deliver pure CO2 that blankets the remaining sparkling wine, ensuring the bottle remains fresh for the next pour. When you are ready for that next glass of bubbly, simply remove the Stopper and pour as much or as little as you like. Now there’s no reason to wait for a special occasion to enjoy a glass of champagne, prosecco, cava, or any other sparkling wine. This bundle includes 1 sparkling charger, 2 sparkling stoppers, and 4 sparkling CO2 capsules. Each capsule preserves up to 7 standard 750ml bottles.
