The Epivac set consists of a pump to create a vacuum in the bottle so that wine will keep longer once opened. How to use it.
Place the cork firmly in the bottle and hold the pump firmly in the center of the cork.
With your other hand, pump several times, at least 10-15, until you feel firm resistance in the pumping action-this indicates a proper seal!
At this point you can remove the pump and store the wine.
To release the wine stopper, tilt the valve stem inside the stopper to eliminate the vacuum effect, remove the stopper from the bottle, and serve!
Corks are reusable and can be purchased separately as replacements
