It is now possible to open a good bottle of wine and only have a glass without the rest going off in the refrigerator. Reducing oxygenation of wine by vacuum sealing caps will delay the wine getting sour. Even wine in bottles supplied with a screw-on top will benefit from the wine bottle vacuum sealing caps. Red wine if stored under vacuum in its original bottle can keep its fresh taste for over a week. A wine bottle vacuum sealing cap can be used with all the models of Lava vacuum packing machines.
