ABSTRACT:
A coffee machine (1) for preparing at least a first coffee beverage at a first brewing pressure and at least a second coffee beverage at a second brewing pressure, the second brewing pressure being higher than the first brewing pressure. The coffee machine is provided with a brewing means (5) which is connected via an outlet line (9) to a tap opening (1). A throttle means (12, 112) is provided in the outlet line (9) and is adjustable between a first and a second flow cross-section, the first flow cross-section being greater than the second flow cross-section. To simplify such a coffee machine in a constructionally simple way in terms of control, the throttle means (12, 112) is made adjustable by the action of the brewing pressure.
