Vacuum Wine Stoppers are designed to be used in combination with our Wine Savers. The Wine Saver system is used to reseal an opened bottle of wine by extracting the oxygen from the bottle, creating a vacuum to preserve your wine for longer. The vacuum can easily be released, which means you can enjoy a glass of wine whenever you want. Our Stoppers can also be used to temporarily seal your wine bottles during parties or dinner parties by simply using the airtight stoppers without crating a vacuum.
