A system for preparing a beverage comprises a beverage maker ( 15 ) and a cartridge ( 10 ) that is removably arranged in the beverage maker ( 15 ). The cartridge ( 10 ) comprises a beverage making unit ( 1 ) having a duct system ( 30 ) for conveying flows of steam and flows of liquid. The duct system ( 30 ) comprises two combinations of ducts ( 31, 32; 41, 42 ), wherein the arrangement of the ducts ( 31, 32; 41, 42 ) of each combination is adapted to enabling a flow of steam to perform a pumping action on a flow of liquid. The beverage maker ( 15 ) comprises a steam generator ( 16 ) having two steam sockets ( 17, 18 ), wherein each of the steam sockets ( 17, 18 ) is in communication with another combination of ducts ( 31, 32; 41, 42 ) of the duct system ( 30 ). As each of the combinations of ducts ( 31, 32; 41, 42 ) is associated with a different steam inlet ( 36, 46 ), and the steam inlets ( 36, 46 ) may be located at different positions on the cartridge ( 10 ), it is achieved that the duct system ( 30 ) may be of a relatively simple design.
