For Red Wine, White Wine & Champagne!
Once open, wine begins to oxidize when it touches air. In order to preserve the remianing wine for several days, it is necessary to remove the air out of the bottle, reduce the oxygen and slow down the process of oxidization, which extends the time of wine freshness.
The automatic wine preserver can pump air out of the bottle and hold out a certain negative pressure. It can also detect the pressure changes in the bottle. When negative pressure values increases, it automatically pumps and maintains the pressure at a stable vacuum state.
