Vacu Vin's Concerto Vacuum Pump pumps air out of an open bottle and reseals it with a reusable rubber stopper. Place the stopper in the neck of the bottle and pump out the air using a vacuum pump. When you reach the optimal vacuum level, you will hear a click. The vacuum slows down the oxidative process, so you can enjoy the clean taste of the wine even after several days. Equipped with a patented click-vacuum indicator, it allows you to slow down the oxidation process.
