HIC Bar's Electric Wine Preserver Stopper Set is the must-have of wine accessories to extract excess air and reseal opened wine bottles with a powerful airtight, liquid-tight vacuum seal. Aerating wine, swirling it in a glass or letting it "breathe" in a wine decanter, is an important step in developing its bouquet and softening its flavor when a bottle is first opened. However, exposure to oxygen for long periods of time deteriorates wine's quality and taste. Our Electric Wine Preserver Stopper Set pumps oxygen out of the bottle and seals in freshness and flavor. The one-button-activated vacuum pump automatically stops once the bottle is properly sealed.
