This wine vacuum pump is a popular option to preserve your wine. It helps make the wine last longer by removing air from the opened bottle in order to slow down the oxidation of the compounds in the wine. Just place one of the two included stoppers into the top of the bottle and use the vacuum to create an air-tight seal. The vacuum works by placing the pump on top of the wine stopper and pulling it up and down to remove the air. You’ll know when to stop the vacuum when you hear a click, indicating the bottle has reached optimum depressurization. This seal can keep your wine fresh for up to a week. Also, the stopper is leak-free so you can even place wine bottles on their sides in the fridge. Finish: White
