Abstract: The method for adjusting the quantity of coffee comprises the steps of: dispensing a predetermined quantity of coffee powder into an infusion chamber (36); by means of an electric actuator (19), closing said infusion chamber compressing the coffee powder in the infusion chamber. The method also provides for detection of at least one parameter of the electric actuator during at least a part of the step to close the infusion chamber and compress the coffee powder; and setting of the quantity of coffee powder dispensed in a subsequent dispensing cycle as a function of said parameter.

Abstract: The machine (1) comprises: at least one infusion unit (29) for preparing coffee, a user interface (9) and an electronic programmable control unit (15). The control unit is associated with a recognition system (11) for recognizing a user, and is programmed to actuate at least one function of the machine based upon the recognition of the user.

Abstract: The machine comprises: a brewing unit (3); a water reservoir (7); a boiler (11) for the production of hot water to supply to the brewing unit; a coffee container (13); an electronic control unit (27); a user interface (33). At least one capacitive sensor (31) is associated to the coffee container to detect the quantity of residual coffee in the container (13). The sensor is connected to the electronic control unit, which is programmed to supply to a user by means of the interface at least a piece of information regarding the quantity of coffee in said container.
