Seal your wine bottle easily with the Zwilling Sommelier wine pump set. Sometimes you have leftover wine and need to preserve the wine and its flavour in the best way possible. Wine oxidises when oxygen has entered the bottle, and you need to remove the oxygen before sealing the bottle. With the Zwilling Sommelier wine pump set and stopper, you can easily pump out the oxygen and seal the opening. You can then easily open the bottle at a later time and continue drinking the wine without it having gone bad.
