The Pulltex Vacuum Wine Saver pumps air out of an opened bottle rather than just sealing the top, which slows the oxidation that turns leftover wine flat and dull. A silicone valve closure gives a watertight seal once the air's been drawn out, so the bottle can be stored upright or on its side without a drip escaping.How the Vacuum WorksA few pumps on top of the stopper draw air out of the bottle, cutting the oxygen available to react with the wine. Less oxygen in contact with the wine means the aroma and flavour hold up for longer than they would under a plain cork or stopper.Doubling as a StopperOnce the air's been pumped out, the valve closure keeps the seal watertight, so the same tool works as a stopper for storage as well as a vacuum pump for preservation.ColoursAvailable in black, navy, maroon, purple, orange and yellow.Pairs WithIf you want a longer preservation window than a vacuum seal gives you, our AntiOx wine saver stopper uses an active carbon filter to keep wine fresh for over a week rather than relying on removing air alone.
