A post-mix beverage dispenser includes a jet, in fluid communication with a source of non-carbonated diluent, extending into a mixing chamber of the dispenser. The jet includes an aperture, typically in a sidewall thereof, configured to spray the diluent towards the wall of the mixing chamber. A diffuser is disposed below the jet. The diffuser may be in fluid communication with a concentrate dispensing outlet so as to emit concentrate into the mixing chamber. The diluent and concentrate collide in the mixing chamber to create a frothed beverage.

What is claimed is: 1. A post-mix beverage dispenser head for creating a frothed beverage, comprising: a spout attached to the dispenser head and cooperatively defining a mixing chamber having an inner wall; a jet disposed within a diluent outlet of the dispenser head so as to be in fluid communication with the diluent and extend into the mixing chamber, the jet including an aperture configured to spray the diluent towards the wall of the mixing chamber generally opposite the jet, wherein the jet comprises a body configured to be inserted into the diluent outlet, and wherein the aperture is formed in a side wall thereof so as to emit the diluent generally transverse to a longitudinal axis thereof; a concentrate dispensing outlet in fluid communication with a source of beverage concentrate and positioned to eject concentrate into the mixing chamber such that the concentrate collides with the diluent spray to create a frothed beverage; and a diffuser disposed in the spout below the jet. 2. The dispenser head of claim 1, wherein the dispenser head includes conduits fluidly connected to the sources of diluent and concentrate, and valves for controlling the flow of diluent and concentrate from the conduits to the mixing chamber. 3. The dispenser head of claim 1, wherein the jet is removably inserted into the diluent conduit outlet. 4. The dispenser head of claim 1, wherein the jet aperture comprises an elongated and narrow aperture. 5. The dispenser head of claim 1, wherein the jet aperture comprises a series of generally aligned apertures. 6. The dispenser head of claim 1, wherein the diffuser comprises a plate having a plurality of apertures therethrough. 7. The dispenser head of claim 6, wherein the diffuser further comprises a hollow shaft extending from the plate and having an end insertable into the concentrate dispensing outlet, and an outlet for emitting concentrate into the mixing chamber. 8. The dispenser head of claim 7, wherein the plate extends outwardly from the shaft. 9. The dispenser head of claim 6, wherein the plate is generally circular and of generally uniform thickness. 10. The dispenser head of claim 8, including a skirt extending outwardly from the shaft above the plate and having a diameter less than that of the plate. 11. The dispenser head of claim 10, wherein the diffuser outlet is formed in the skirt so as to be in fluid communication with the hollow shaft. 12. The dispenser head of claim 11, wherein the outlet comprises a plurality of spaced apart apertures formed through the skirt and in fluid communication with the hollow shaft. 13. The dispenser head of claim 7, wherein the diffuser outlet comprises an aperture formed in the hollow shaft. 14. The dispenser head of claim 13, wherein the aperture comprises an elongated and narrow aperture. 15. The dispenser head of claim 1, wherein the jet body comprises a tube having an open end insertable into the diluent outlet, and closed end. 16. A post-mix beverage dispenser head for creating a frothed beverage, comprising: a mixing chamber defined by an outlet spout attached to the dispenser head, the dispensing head including inlet conduits fluidly connected to sources of diluent and concentrate, and valves for controlling the flow of diluent and concentrate from the inlet conduits to the mixing chamber; a jet extending from the diluent conduit and into the mixing chamber, the jet including an aperture formed in a sidewall thereof and configured to spray the diluent towards a wall of the mixing chamber generally opposite the jet; and a diffuser having a hollow tube in fluid communication with the beverage concentrate conduit, a plate extending from the shaft and having a plurality of apertures formed therein, and an outlet formed in the diffuser above the plate for ejecting concentrate into the mixing chamber such that the concentrate collides with the diluent spray to create a frothed beverage. 17. The dispenser of claim 16, wherein the jet is configured to be removably inserted into the outlet of the diluent conduit, and wherein the aperture comprises an elongated aperture or series of apertures formed in a the side wall thereof so as to spray the diluent in a generally horizontal direction. 18. The dispenser of claim 17, wherein the diffuser is removably inserted into the outlet of the concentrate conduit. 19. The dispenser of claim 16, including a skirt extending outwardly from the shaft above the plate and having a diameter less than that of the plate. 20. The dispenser of claim 19, wherein the diffuser outlet is formed in the skirt and in fluid communication with the hollow shaft. 21. The dispenser of claim 20, wherein the diffuser outlet comprises a plurality of spaced apart apertures formed in the skirt and in fluid communication with the hollow shaft. 22. The dispenser of claim 16, wherein the diffuser outlet comprises an elongated aperture formed in the hollow shaft. 23. A diffuser for use in a post-mix beverage dispenser head having an outlet spout attached to a dispensing head, the dispensing head including conduits fluidly connected to sources of diluent and concentrate, and valves for controlling the flow of diluent and concentrate from the conduits, the diffuser comprising: a hollow shaft having an open end insertable into the concentrate dispensing outlet; a single plate extending outwardly from the shaft adjacent to an opposite closed end thereof, the plate having a plurality of apertures formed therein; and an outlet formed in the hollow shaft above the plate for emitting the concentrate for mixing with the diluent. 24. The diffuser of claim 23, wherein the plate is generally circular and of generally uniform thickness. 25. The diffuser of claim 23, including a skirt extending outwardly from the shaft above the plate and having a diameter less than that of the plate. 26. The diffuser of claim 25, wherein the diffuser outlet comprises a plurality of spaced apart apertures formed in the skirt and in fluid communication with the hollow shaft. 27. The diffuser of claim 23, wherein the diffuser outlet comprises an elongated aperture formed in the hollow shaft. 28. A diffuser for use in a post-mix beverage dispenser head having an outlet spout attached to a dispensing head, the dispensing head including conduits fluidly connected to sources of diluent and concentrate, and valves for controlling the flow of diluent and concentrate from the conduits, the diffuser comprising: a central hollow shaft defining a bore extending therewithin that terminates in a closed end, an open end of the shaft insertable into the concentrate dispensing outlet such that the concentrate flows into the bore; a plate defining a plurality of apertures extending outwardly from the shaft in spaced relation to the open end of the shaft; and a concentrate outlet formed in the hollow shaft, so as to fluidly communicate with the bore, above the plate for emitting the concentrate for mixing with the diluent, such that the diluent impinges upon the concentrate in a turbulent manner to create a fluid-foam mixture before the mixture passes over the plate and dispensed through the outlet spout. 29. The diffuser of claim 28, including a skirt extending outwardly from the shaft above the plate and having a diameter less than that of the plate. 30. The diffuser of claim 29, wherein the diffuser outlet comprises a plurality of spaced apart apertures formed in the skirt and in fluid communication with the bore of the hollow shaft. 31. The diffuser of claim 28, further including a jet seated within the diluent outlet, the jet including a diluent inlet for receiving diluent from the diluent outlet, and a diluent outlet such that the diluent exits the outlet at an increased velocity in relation to that at which it flows through the diluent outlet.
