摘要：
A method for producing a coffee beverage, using ground coffee in a brewing chamber of a coffee machine including a control unit and a brewing cylinder housing a movably arranged piston having a piston drive for providing a changeable volume for the brewing chamber. An amount of ground coffee is filled into the brewing chamber. Water is conduct through the ground coffee in the brewing chamber to prepare the coffee beverage. A volume flow of water flowing through the brewing chamber is determined and compared to a desired value for the volume flow. An adjustment value of the piston position is changed, thus changing the pressing force exerted onto the ground coffee, in the brewing chamber as a function of deviations from the desired value for the volume flow to control the volume flow until a desired volume flow is reached.
