Claim 1:
2. A coffee machine, comprising
the grinding device of claim 1, the grinding device for grinding coffee beans into coffee powder with a determined grind size;
a decoction device with an extraction chamber in which a quantity of coffee powder taken away from the grinding device is received, which decoction device is intended and configured to compress the coffee powder into a bed in the extraction chamber using a pressing force;
an inlet for hot water on an inlet side of the extraction chamber and an outlet for the obtained coffee extract on an outlet side of the extraction chamber;
water supply means which are able and configured to guide a quantity of water with increased temperature to the inlet under increased pressure via a water conduit;
an outflow at which a coffee product can be taken away and which is connected to the outlet of the extraction chamber over a product conduit; and
an electronic control unit which is able and configured to impart at least a preset to the coffee machine, comprising one or more of the grind size, the quantity of coffee powder, the pressing force, the quantity of water, the increased pressure and the increased temperature,, wherein the electronic control unit is coupled to at least one sensor which is able and configured to register a liquid flow speed through the coffee machine and generate it in the form of an electronic value, particularly a flow speed of a product flow through the product conduit from the extraction chamber or of a water flow through the water conduit to the extraction chamber, wherein the liquid flow can be adjusted at least partially by a fine-tuning and is controlled by the electronic control unit, and wherein the electronic control unit is able and configured on a basis of a received value of the liquid flow speed to impart a fine-tuning to the coffee machine, whereby the liquid flow speed can be tuned to a predetermined value.
