A method and apparatus for improving the carbonation in a soda fountain drink when served in a cup (702, 860, 166). A carbonation concentrator (100) is inserted between the fountain head (700) and the bottom portion of the cup to cause backpressure at a point within the fluid in the cup as the soda is poured, increasing the absorption of the carbon dioxide carbonation into the poured fluid. The carbonation concentrator may be attached to an otherwise conventional fountain head, formed integrally therewith, or to a lid (162). In disclosed embodiments, the carbonation concentrator is slid over the spout of a hand-held or wall-mounted fountain head and secured in an appropriate fashion. The carbonation concentrator includes a hollow interior passage (150, 810, 163) allowing relatively unrestricted passage of the mixed drink directly toward the bottom of the cup.
