The invention claimed is: 1. A cartridge containing one or more liquid beverage ingredients and being formed from substantially air-and water-impermeable materials, the cartridge comprising an inlet for the introduction of an aqueous medium into the cartridge, a compartment containing the one or more liquid beverage ingredients and an outlet for a beverage produced by dilution of the one or more liquid beverage ingredients by the aqueous medium, the compartment includes means for controlling dilution of at least a proportion of the one or more liquid beverage ingredients on introduction of the aqueous medium into the compartment, the means for controlling dilution delays dilution of at least a proportion of the one or more liquid beverage ingredients on introduction of the aqueous medium into the compartment, in use, an aqueous medium flow path is established from the inlet to the outlet, the means for delaying dilution comprising a partition which hinders entry of at least a proportion of the one or more liquid beverage ingredients into the aqueous medium flow path, the partition includes four apertures for controllably releasing the at least a proportion of the one or more liquid beverage ingredients into the aqueous medium flow path and the partition comprises a cup-shaped member having an open mouth directed away from the aqueous medium flow path. 2. A cartridge as claimed in claim 1 wherein the cup-shaped member is annular. 3. A cartridge as claimed in claim 2 wherein one or more apertures are provided at or near a base of the cup-shaped member. 4. A cartridge as claimed in claim 3 wherein the at least a proportion of the liquid beverage ingredients in the cup-shaped member drain by gravity through the one or more apertures in use. 5. A cartridge as claimed in claim 4 wherein the cup-shaped member is spaced from a bottom of the cartridge, such that the aqueous medium flow path passes between the cup-shaped member and the bottom of the cartridge. 6. A cartridge as claimed in claim 5 wherein the at least a proportion of the liquid beverage ingredients in the cup-shaped member drain by gravity through the one or more apertures in use vertically downwards into the aqueous medium flow path. 7. A cartridge as claimed in claim 6 comprising an inner member and an outer member, wherein the inner member comprises the cup-shaped member. 8. A cartridge as claimed in claim 7 further comprising means for producing a jet of the beverage, wherein said means for producing the jet of the beverage comprises an aperture in the aqueous medium flow path. 9. A cartridge as claimed in claim 8 wherein the aperture is delimited by an interface between the inner member and the outer member. 10. A cartridge as claimed in claim 9 further comprising at least one inlet for air and means for generating a pressure reduction of the jet of beverage, whereby, in use, air from the at least one air inlet is incorporated into the beverage as a plurality of small bubbles. 11. A cartridge as claimed in claim 10 wherein the at least one air inlet is provided in the inner member downstream of the aperture. 12. A Cartridge as claimed in claim 11 wherein the at least one air inlet and means for producing a pressure reduction in the jet of beverage produces a foaming of the one or more liquid beverage ingredients of greater than 40%. 13. A cartridge as claimed in claim 12 wherein the foaming is greater than 70%. 14. A cartridge as claimed in claim 13 wherein the cartridge is disc-shaped. 15. A cartridge as claimed in claim 14 wherein the outer member and/or inner member are formed from polypropylene. 16. A cartridge as claimed in claim 15 wherein the outer member and/or inner member is formed by injection moulding. 17. A cartridge as claimed in claim 16 wherein the liquid beverage ingredient is a concentrated liquid milk composition. 18. A cartridge as claimed in claim 17 wherein the concentrated liquid milk contains between 25 and 40% total solids. 19. A cartridge as claimed in claim 18 wherein the concentrated liquid milk contains 30% total solids. 20. A cartridge as claimed in claim 19 wherein the concentrated liquid milk contains between 0.1 and 12% fat. 21. A cartridge as claimed in claim 16 wherein the one or more liquid beverage ingredients are selected from the group of cocoa solids, coffee, tea, sweeteners, cordials, flavourings, alcoholic beverages, flavoured milk, fruit juices, squashes, sauces and desserts. 22. A cartridge containing one or more liquid beverage ingredients and being formed from substantially air-and water-impermeable materials, the cartridge comprising: an inlet for the introduction of an aqueous medium into the cartridge; a compartment containing the one or more liquid beverage ingredients; an outlet for a beverage produced by dilution of the one or more liquid beverage ingredients by the aqueous medium; and a cup-shaped member disposed in the compartment and containing at least a portion of the one or more liquid beverage ingredients, the cup-shaped member having an open mouth directed away from an aqueous medium flow path between the inlet and the outlet and having a plurality of feed apertures directed toward the flow path to permit the one or more liquid beverage ingredients in the cup-shaped member to enter the flow path. 23. A cartridge as claimed in claim 22 wherein the flow path includes an inward segment along an underside of the cup-shaped member opposite the open mouth. 24. A cartridge as claimed in claim 22 wherein outlet includes an outlet spout and the cup-shaped member surrounds at least a portion of the outlet spout. 25. A cartridge as claimed in claim 24 wherein the compartment is bounded in part by a disc-shaped outer member having an open end closed by a lid and the feed apertures are directed toward the lid. 26. A cartridge as claimed in claim 24 wherein a manifold is disposed between the inlet and the compartment, the manifold having a plurality of openings directing the aqueous medium toward the outlet spout. 27. A cartridge as claimed in claim 25 wherein the plurality of openings of the manifold direct the aqueous medium toward the underside of the cup-shaped member. 28. A cartridge as claimed in claim 25 wherein the open mouth of the cup-shaped member faces away from the lid and the inward segment of the flow path is between the underside of the cup-shape member and the lid. 29. A cartridge as claimed in claim 28 wherein the cup-shaped member includes an inner wall spaced from the outlet spout and the flow path includes a segment away from the lid and between the inner wall of the cup-shaped member and outlet spout and the flow path includes a segment in the outlet spout toward the lid. 30. A cartridge as claimed in claim 29 wherein the outlet spout is disposed in a chute having an open end facing the lid, the chute having a sidewall positioned between the outlet spout and the inner wall of the cup-shaped member, and an air inlet being provided between the chute and the outlet spout to permit introduction of air into the beverage when dispensed through the outlet spout.
