Preserve the crisp flavor and effervescence of your favorite sparkling wines for up to 4 weeks with the Coravin sparkling wine preservation system. The universal-fit sparkling stopper locks securely on virtually any bottle from a half to a magnum, while the sparkling charger delivers 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 to pour. Now there's no reason to wait for a special occasion to enjoy a glass of champagne, prosecco, cava or any other sparkling wine.
