The dispensing valve assembly according to claim 1, wherein said one-piece base is formed by injection molding. 7. The dispensing valve assembly according to claim 1, said gas passageway having a T-shape. 8. The dispensing valve according to claim 1, said at least one generally horizontally oriented radial pipe section having two opposing inlet orifices radially spaced 180 degrees apart, and connected to said vertically oriented pipe section at the center axis. 9. The dispensing valve assembly according to claim 1, said at least one generally horizontally oriented radial pipe section comprising three radial pipe sections radially spaced 120 degrees apart which intersect at the center axis of said base and connect to said vertically oriented pipe section at the center axis. 10. The dispensing valve assembly according to claim 1, wherein said gas passageway may be jetted and the flow rate of the air into the container is operative to be controlled according to the number radial pipe sections comprising the at least one generally horizontally oriented radial pipe section. 11. The dispensing valve assembly according to claim 1, wherein said gas passageway is operative to be jetted and the flow rate of the air into the container may be controlled according to the diameter of the at least one generally horizontally oriented radial pipe section and said vertically oriented pipe section. 12. The dispensing valve assembly according to claim 1, wherein when said cap is pulled upward to an open position, simultaneously, (1) said annular liquid passageway is opened so that liquid may be expelled from said container, and (2) said at least one inlet orifice is unobstructed so that gas is allowed to enter the container via said gas passageway. 13. The dispensing valve assembly according to claim 1, wherein when said cap is pushed downward to a closed position, simultaneously, (1) said annular liquid passageway is closed so that liquid may not be expelled from said container, and (2) said at least one inlet orifice is obstructed so that gas is not allowed enter the container via said gas passageway. 14. A liquid dispensing valve with a vacuum release feature for a liquid container comprising: a one-piece injection molded mounting base, said base comprising, a cylindrical mounting collar; an enclosure portion connected to a top edge of said mounting collar forming an inner cavity within said base; a spout having a first cylindrical portion positioned above said enclosure portion and about a center axis of said base, said first cylindrical portion connected to a top surface of said enclosure portion, said first cylindrical portion having a distal dispensing tip, said spout having an inner axial core positioned within an upper portion of said first cylindrical portion forming an annular liquid passageway, said core fastened to an inner radial surface of said first cylindrical portion with radial oriented support ribs, wherein liquid flows from said inner cavity though said annular liquid passageway and exits from an annular opening at said dispensing tip; a gas passageway separate from said annular passageway, having at least one inlet orifice located on an outer surface of said first cylindrical portion, a radial pipe section of said gas passageway being integrally formed within at least one of said radial ribs and within said inner axial core of said spout, said gas passageway further routed through a pipe extension having an exit orifice, said pipe extension attached to a bottom side of said core along the center axis of said base and projecting downward into said inner cavity; and a cap having a second cylindrical portion and top portion with a drain port, said cap slip-fit over said spout and adapted to be pulled upward to simultaneously open said liquid and gas passageways, adapted to be pushed downward to close said liquid and gas passageways simultaneously, wherein said core protrudes through said drain port to prevent liquid flow when said cap is pushed downward, and wherein an inner radial wall of said second cylindrical portion blocks the at least one inlet orifice preventing gas flow. 15. The dispensing valve according to claim 14, said base adapted to accept a hermetically-sealed container opening without puncturing the seal. 16. The dispensing valve according to claim 14, further comprising receiving threads on an inside surface of said mounting portion, said threads adapted to be screwed onto a threaded container top. 17.
