The wine saver pumps oxygen out of an opened wine bottle and reseals it with a wine stopper. The sealing condition will slow down the deterioration of wine, which will preserve the wine for up to 7 days.
For a half-full wine bottle, it should take about 15-20 seconds of steady pumping to achieve a vacuum seal. When you want to taste the wine again, simply pull the center of the stopper to break the seal and remove it.
