6. The system according to claim 1 , wherein the cartridge holder has a liquid connection.

7. The system according to claim 1 , wherein the cartridge holder has a release element in order to transfer the piercing means of the cartridge receptacle from a retracted position into an extended position.

8. The system according to claim 7 , wherein the cartridge holder comprises a fastening flange which engages around the cartridge receptacle in a form-fitting and/or force-fitting manner during or after insertion into the cartridge holder.

9. The system according to claim 8 , wherein the fastening flange comprises a release mechanism which is configured such that actuation of the release mechanism results in the fastening flange engaging around the cartridge receptacle and/or in the fastening flange being shifted such that a relative movement between the cartridge receptacle and the release element in contact with the piercing means is generated, with the result that the piercing means is transferred from the retracted position into the extended position.

10. The system according to claim 9 , wherein the release mechanism comprises a hand lever for a manual actuation thereof, wherein, the hand lever is configured to be rotatable about an axis of rotation substantially parallel to a longitudinal axis of the cartridge.

11. The system according to claim 10 , wherein the release mechanism comprises a transmission which converts a rotary movement of the hand lever about the axis of rotation parallel to the longitudinal axis into a movement in translation substantially parallel to the longitudinal axis, in particular into raising or lowering of the cartridge receptacle.

12. The system according to claim 1 , wherein the dispenser has a support for a container in which a finished beverage or foodstuff is collected; and

wherein the support is intended to be pivotable and/or vertically adjustable.

13. The system according to claim 1 , wherein the cartridge receptacle has:

i) an inflow for a diluent;

ii) a mixing chamber in which the diluent and a beverage substrate and/or a foodstuff substrate are mixed; and

iii) an outflow; and

wherein, with regard to a direction of flow of the diluent, a flow cross section is first expanded and then reduced again.

14. The system according to claim 13 wherein the mixing chamber has a protuberance.

15. The system according to claim 14 , wherein the outflow is provided in the protuberance.

16. The system according to claim 1 , wherein the cartridge receptacle has a spike guide in which the piercing means is mounted in a displaceable manner; and

wherein the piercing means is displaceable between a retracted position, in which the piercing means is away from the membrane, and an extended position, in which the piercing means pierces the membrane of the cartridge and projects into the cartridge.

17. The system as claimed in claim 16 , wherein at least one lateral channel for conveying a beverage substrate and/or a foodstuff substrate in a direction of a mixing chamber when the membrane is pierced by the piercing means has been introduced into an outer wall of the piercing means.

18. The system according to claim 1 , wherein the system is configured such that the compressed-air connection is coupled to the compressed-air outlet of the cartridge holder when the cartridge receptacle has been inserted into the cartridge holder and/or a release mechanism for a fastening flange is actuated.

19. The system according to claim 13 , wherein the inflow and the outflow are provided at opposite ends of the cartridge receptacle.

20. The system according to claim 13 , wherein the piercing means is provided in a manner aligned with the inflow and the outflow.

21. The system according to claim 1 , wherein the cartridge is provided on or in the cartridge receptacle;

wherein the cartridge has a wall region, one end of which is adjoined by a connecting region which is closed by the membrane, and at the opposite end of which a bottom region is provided; and

wherein the wall region and the bottom region define a cavity which accommodates a beverage substrate and/or a foodstuff substrate.

22. The system according to claim 21 , wherein the connecting region has at least one flange which is provided with a positioning means and/or a covering means.

23. The system according to claim 22 , wherein the positioning means and/or the covering means is an indentation and/or a protuberance which protrudes from a circumference of the at least one flange.

24. The system according to claim 21 , wherein a neck is provided between the wall region and the connecting region.

25. The system according to claim 22 , wherein the membrane is fastened by being sealed to the at least one flange.

26. The system according to claim 21 , wherein the cartridge receptacle is releasably fastened to the connecting region of the cartridge.

27. The system according to claim 22 , wherein the at least one flange cooperates in a sealing manner with the cartridge receptacle.

28. The system according to claim 21 , wherein the cartridge and the cartridge receptacle are connected together in a rotationally fixed manner.

29. The system according to claim 21 wherein a covering means covers an outflow of the cartridge receptacle.

30. The system according to claim 1 , wherein the cartridge is provided with a product identifier;

wherein the product identifier is arranged on a side of the cartridge that faces an identifier detector; and

wherein the cartridge has a substantially planar surface portion in a region of the product identifier.

31. The system of claim 1 , wherein the compressed-air source is configured to inject the compressed air into the cartridge after a product identifier is read by an identifier detector, evaluated by an evaluation unit, and verified by the evaluation unit.

32. The system according to claim 1 , wherein the dispenser has an identifier detector configured to read a product identifier on the cartridge, the cartridge receptacle, or both, and wherein the identifier detector is arranged above the cartridge holder, behind the cartridge holder, or both.
