1. A system for receiving, storing, and dispensing a liquid with minimal exposure of said liquid to ambient air, said system comprising: a storage container comprising a top, a bottom, and one or more upright sidewalls, wherein said top, bottom, and sidewalls cooperatively define an internal volume

1. A system for receiving, storing, and dispensing a liquid with minimal exposure of said liquid to ambient air, said system comprising: a storage container comprising a top, a bottom, and one or more upright sidewalls, wherein said top, bottom, and sidewalls cooperatively define an internal volume configured to receive and hold said liquid;a shiftable barrier positioned in said internal volume and dividing said internal volume into a lower portion and an upper portion, wherein said barrier is shiftable between a lowermost position and an uppermost position, wherein said barrier is sized to fill at least 90 percent of the horizontal cross-sectional area of said internal volume defined by said upright sidewalls;a liquid inlet disposed below at least a portion of said barrier when said barrier is in said lowermost position;an elongated liquid extraction member coupled in fluid flow communication with said liquid inlet of said storage container, wherein said liquid extraction member extends from said liquid inlet and includes a free end that is configured to be received within a wine bottle;at least one differential pressure creation device coupled in fluid flow communication with the wine bottle, for causing said liquid to flow from the wine bottle, through said liquid extraction member, and into said internal volume of said storage container; andat least one vent configured to permit gas to flow through and/or around said barrier from said lower portion of said internal volume to said upper portion of said internal volume. 2. The system according to claim 1, wherein said shiftable barrier is configured to float upwardly on said liquid in said internal volume as said liquid enters said internal volume. 3. The system according to claim 1, wherein said liquid extraction member has a length that is at least 2 times greater than the maximum diameter of said liquid extraction member, wherein said length is at least 4 inches and/or not more than 40 inches. 4. The system according to claim 1, wherein the maximum internal diameter of said liquid storage container is at least 1.5 times greater than the maximum internal diameter of said liquid extraction member. 5. The system according to claim 1, wherein said vent is at least partially formed by an opening extending through said barrier and spaced inwardly from said one or more sidewalls. 6. The system according to claim 1, wherein said top is detachable from said sidewalls. 7. The system according to claim 1, wherein said vent is at least partially formed by a gap between said barrier and said one or more sidewalls. 8. The system according to claim 1, wherein said container comprises a gas outlet configured to release gas from said upper portion of said internal volume as said barrier shifts upwardly toward said upper position. 9. The system according to claim 1, wherein said differential pressure device comprises a compression pump, a vacuum pump, a siphon, or a plunger. 10. The system according to claim 1, wherein said storage container comprises a liquid outlet disposed below at least a portion of said barrier when said barrier is in said lowermost position, wherein said liquid inlet and said liquid outlet are formed by a common opening. 11. The system according to claim 10, further comprising a spigot coupled in fluid communication with said liquid outlet and configured to dispense liquid from said container. 12. The system according to claim 1, wherein said liquid is wine. 13. The system according to claim 12, wherein said liquid extraction member has a length that is at least 2 times greater than the maximum external diameter of said liquid extraction member, wherein said length is at least 4 inches and not more than 40 inches. 14. The system according to claim 12, wherein said container comprises a liquid outlet disposed below at least a portion of said barrier when said barrier is in said lowermost position, wherein said liquid inlet and said liquid outlet are formed by a common opening. 15. The system according to claim 12, wherein said shiftable barrier is configured to float upwardly on said liquid in said internal volume as said liquid enters said internal volume. 16. The system according to claim 12, wherein said system further comprises one or more additional storage vessels coupled in fluid flow communication with said storage container, and wherein said system further comprises an additional shiftable barrier received in each of said storage vessels.
