In a coffee brewing apparatus, a milling assembly produces coffee powder which is filled into a brewing chamber. Then the brewing chamber is closed by a displaceable piston in order to exert a preselected pressure on the coffee powder in the brewing chamber, and hot water is forced through the compressed coffee powder. If it is recognized after several subsequent preparation cycles that too much or too less coffee powder has been filled into the brewing chamber, the operation period of the milling assembly is shortened or extended automatically under the...
A method of preparing coffee comprising cyclically repeated steps of: feeding coffee beans to a coffee bean milling means; milling the coffee beans to a coffee powder having a selected average grain size; adding a selected amount of the coffee powder into a brewing chamber; displacing a piston into the interior of the brewing chamber and thereby reducing the internal volume of the brewing chamber containing the coffee powder until a preselected pressure is exerted on the coffee powder; supplying a preselected amount of hot water into the brewing chamber ...
