Abstract
A machine for the preparation and dispensing of espresso coffee comprises: a coffee boiler, a filter holder with a filter for a pressed coffee powder puck, and a pre-infusion chamber and a hydraulic circuit for transporting pressurized water from the coffee boiler to the pre-infusion chamber. The machine further comprises a device for detecting a parameter indicative of the filling of the pre-infusion chamber and of the hydraulic circuit so that the step of dispensing of an espresso coffee can be started on the basis of the detected filling parameter.
