Abstract
An espresso coffee machine is described, said machine comprising: a water supply; a boiler for heating the water; a pump; a dispensing group configured to cooperate with a portafilter equipped with a filter basket with a puck of coffee powder, the machine being configured to supply pressurized water to said coffee powder puck for dispensing an espresso coffee, and a water monitoring system for monitoring at least one parameter of the water used for preparation of the espresso coffee. Preferably, the monitoring system comprises a conductivity and temperature probe which provides values, continuously and in real time, of water hardness derived from information on the electrical conductivity and temperature of the water.
