A method and apparatus are disclosed for filling specially-designed beverage containers from the bottom through a one-way port. One embodiment of the invention employs an umbrella valve ( 19 ) mounted in a perforated stopper ( 18 ), which is interference-fitted into the bottom of a beverage container ( 11 ). When brought into contact with concentric o-ring seals ( 12,17 ) on a fluid delivery assembly ( 13 ), vacuum suction ( 14, 16 ) fixtures the beverage container ( 11 ) down to the fluid delivery assembly ( 13 ), creating a liquid-tight channel for fluids to be fed through. Fluids originate in a pressurized reservoir and are fed through a fluid feed-in ( 15 ), forcing the umbrella valve ( 19 ) open and allowing flow of fluid into the interior volume ( 20 ) of the beverage container. Upon completion of filling, the reservoir is depressurized, allowing the umbrella valve ( 19 ) to snap shut. The beverage container ( 11 ) can now be decoupled from the fluid delivery assembly ( 13 ) and employed as desired. Other embodiments are described and shown.
