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.
