Abstract: The present invention is directed to an apparatus for transferring a liquid from a source container to a destination container including a liquid transfer mechanism; at least one unidirectional valve preventing backflow into the source container; a source needle, inserted into a sealed closure of the source container, withdrawing the liquid from the source container; a destination needle, inserted into a sealed closure of the destination container, depositing the liquid into the destination container; an inert gas container supplying an inert gas to the source container; and at least one vent check valve releasing pressure from at least one of the containers when the pressure in the container exceeds a predetermined pressure limit. The present invention transfers liquids such as wine from an original sealed container into various new containers under controlled conditions without compromising the original composition of the liquids.
