A brewing assembly for a coffee machine, which brewing assembly includes a brewing module with a brewing head, an upper and lower closure element, and a drive module with at least one linear guide element. The brewing head has a cylindrical brewing chamber, which can be closed by the upper and lower closure elements and cooperates with the linear guide such that the brewing head is displaceable linearly in the brewing assembly. The drive unit also includes a motor drive for the linear guide element. The brewing head and at least one of the two closure elements with at least a brewing chamber are arranged in the brewing module in a linearly displaceable fashion. The brewing module is arranged detachably in or on the drive unit such that when it is in or on the drive unit at least the brewing head is linearly displaceable via the linear guide element.
