This Automatic Wine Preserver automatically pumps air out of an opened bottle of wine to help prevent oxidation, which can degrade flavor and bouquet. Simply insert into an opened bottle, secure, and the vacuum automatically removes all excess air to help keep your wine fresher between glasses.

It features a built-in thermometer that monitors the wine temperature to help you serve it at the correct temperature. It measures and displays temperature in Celsius or Fahrenheit and shows the number of days bottle has been open on an easy-to-read backlit LCD readout. There's even a screen that tells you when you last opened the bottle. The preserver fits most 750mL bottles, with a low-profile design that fits easily in a fridge and in or under a cabinet.
