Abstract: Wine within an opened bottle is preserved by introducing an inert gas through a seal which seals the previously opened bottle. An adapter seals the bottle and the inert gas is injected into the bottle through the seal from a removable gas supply. The gas supply attaches to the adapter in an airtight manner while the adapter seals the wine bottle in an airtight manner. The gas supply can be removed from the adapter and used with other adapters to preserve other bottles of wine while each adapter seals the inert gas within a respective bottle of wine until consumption of the wine in a particular bottle is to resume.
