Abstract: Vacuum bottle stoppers for wine, particularly suited for partially consumed bottles of wine are disclosed. Systems are also disclosed for evacuating a partially consumed bottle of wine, filling the wine bottle head space with an inert or other gas and the storing the wine bottle while maintaining the inert or other gas in the bottle. The stopper has a vacuum valve and a vacuum indicator in a removable cap. The vacuum valve has a self-closing passageway due to the passageway traversing an elastomeric material. The vacuum indicator moves in response to vacuum and reveals a marking on a valve opener when a desired vacuum is achieved.

Abstract: A bottle stopper is provided having a cylindrical body formed of a resilient, flexible, elastic material that includes a first cylindrical section adapted to be inserted into an opening of a bottle in sealing engagement with the bottle and a second cylindrical section disposed adjacent the first cylindrical section for extending above the opening of the bottle when the first cylindrical section is inserted in sealing engagement with the bottle. An air passageway is disposed adjacent and extends longitudinally along substantially at least the length of the first cylindrical section and along the internal periphery of the cylindrical body. A visual indicator, preferably a spout, is disposed on an outer surface of the second cylindrical section for identifying the relative location of the air passageway with respect to the visual indicator.
