The invention relates to a brewing method including providing a capsule into a brewing module with a brewing liquid injector and a brewed product discharging device, said capsule having a covering surfaces on an extraction side and an injection side, said injector having at least one perforation element for each of the injection and extraction sides； closing a brewing chamber of the brewing module so that the at least one perforation element pierces the injection-side covering surface along a cutting line； introducing under pressure a brewing liquid into the region between the injection-side supporting surface and the injection-side covering surface in such a manner that the pressure of the liquid causes the extraction-side covering surface to be displaced towards the interior of the capsule wherein brewing liquid then enters the capsule； and maintaining said pressure until the brewed product emerges from discharge openings produced in the extraction-side covering surface.
