In an espresso coffee maker having an espresso brew unit ( 1 ) and a coffee outflow duct ( 18 ) in fluid-conductive connection with the espresso brew unit via a crema valve ( 15 ) and having an end sided coffee outflow ( 19 ), no brewed residual coffee should remain in the coffee outflow duct nor leak out, for instance as leakage, through the coffee outflow. In order to avoid this, a return-flow suction unit ( 21 ), which is preferably independent except for a drive means, is in fluid-conductive connection with the coffee outflow duct ( 18 ) between crema valve ( 15 ) and coffee outflow ( 19 ), which is automatically activated when a brewing process is finished.
