The system according to claim 1, wherein said foam formation preventing surface, or a part provided with that surface, is removable from said receiving chamber or another part of the system. 11. The system according to claim 1, wherein said foam formation preventing surface extends at a distance from said nozzle, a distance in a range of approximately 1 mm-2 cm. 12. The system according to claim 1, wherein the system is provided with a beverage jet receiving body which is placeable or is placed downstream relative to said nozzle, which body is designed to substantially counteract or prevent formation of foam of said beverage when the beverage is spouted onto or in said body in the first configuration. 13. The system according to claim 12, wherein said beverage jet receiving body is placeable or is placed in said receiving chamber. 14. The system according to claim 13, wherein said receiving body is provided with said foam formation preventing surface. 15. The system according to claim 13, wherein said receiving body can be brought at least from a foam preventing position, downstream relative to the nozzle, to another position, in which other position the receiving body is not used or cannot be used for counteracting or preventing foam formation. 16. The system according to claim 12, wherein said receiving body extends substantially at a distance from a bottom of the receiving chamber. 17. The system according to claim 12, wherein, during use, said receiving body is arranged substantially centrally in said receiving chamber. 18. The system according to claim 1, wherein the system is designed such that, during use in the first configuration, the system substantially prevents turbulence of said beverage when the beverage is spouted towards and/or into the receiving chamber. 19. The system according to claim 1, wherein the system is designed such that, during use, the system substantially prevents the beverage spouted towards and/or in to the receiving chamber from taking in air. 20. The system according to claim 1, wherein the system is designed for, during use, dispensing beverage under pressure to the nozzle, which pressure is in the range of approximately 1.0-1.8 bar. 21.
