The Vacuum Wine Stoppers are used in combination with the Vacuum Wine Saver, which is sold separately. The Vacuum Wine Saver is a vacuum pump that pumps air from an open bottle so that it is resealed with a reusable rubber Vacuum Wine Stopper. Place the cap in the bottle neck and remove the air using the pump. The oxidation process of the wine is slowed down by the vacuum, allowing you to enjoy your wine again at a later time.
