Abstract:
Provided is a brewing device for an espresso maker having a brewing chamber for receiving grounds, a pressing ram mounted movably on a path of travel extending between a top position and a bottom compaction position in which it penetrates into said brewing chamber to form a cake of compacted grounds, a hydraulic drive mechanism for the pressing ram having a hydraulic pump and means for measuring the volume of hydraulic fluid injected into the drive mechanism. The brewing device has a control circuit that determines the height of the cake of compacted grounds from signals delivered by the volume measurement means during the travel of the pressing ram.
