(DC210) The Wine Saver is a vacuum pump which easily extracts the air from opened bottles of wine with just 4 or 5 pumps. It re-seals the bottle with a special reusable rubber stopper. Removing air from partially empty bottles slows down flavor destroying oxidation, keeping the wine fresh and alive for longer periods of time. The same bottle can be opened and re-sealed as many times as you like. Comes with one reusable stopper.
