In a method and an associated brewing apparatus for preparing a hot beverage, in particular a coffee beverage, in which a quantity of a flavouring source, in particular coffee powder, is introduced into a brewing chamber (12) and then, in a brewing operation, a predeterminable overall quantity of brewing water is passed through the brewing chamber (12) under pressure, the taste quality of the freshly brewed coffee beverages is enhanced, or at least the consistency of the taste of coffee beverages prepared one after the other is increased, in that, during the brewing operation, a value for the volume flow of the brewing water upstream or downstream of the brewing chamber (12), and/or for the quantity of the brewing water which has already been passed through, or is still to be passed through, is determined continuously, or at least a number of times, and a controllable counterpressure valve (9) arranged preferably downstream of the brewing chamber, as seen in the throughflow direction, is activated in accordance with the value determined. The counterpressure valve (8) is designed as a motor-operated needle valve which the controller (10) opens wider or closes by activating a corresponding drive motor (20). |
