Once a bottle of wine has been opened and poured it is exposed to more air which starts the process of oxidizing a wine immediately. It is this process that renders a nice bottle of wine undrinkable over a short period of time.
In order to stop the oxidizing of the wine it is imperative to remove the Oxygen molecules for coming in contact with it. Simply insert the WineLife straw into the neck of the wine bottle and press the trigger down for 2 seconds.
With the application of the WineLife preservation system to the open bottle, the wine is now being protected from the Oxygen molecules effectively stopping any oxidization of the wine. You are now free to recork/reseal your wine with the knowledge that it will drink wonderfully the next time you open it.
