A device for protecting wine against the harmful oxidation and spoilage resulting from ullage (air space) which develops in wine aging containers. An inflatable bladder within the container, but free of contact with the inner surface thereof, is in communication with a reservoir of water disposed above the container, enabling it to expand to replace the volume of wine that normally seeps out of the container. A second duct allows the escape of air usually trapped, and a third duct may be opened to allow the water in the bladder to force out a sample of wine for tasting.
