The method involves preceding the infusion of the coffee with a stage in which the coffee powder is soaked (preinfused) with a gradual increase in the pressure. The improvement located on the delivery pipe of an espresso coffee machine, immediately upstream of the infusion group, is a pressure damping device. This allows improved imbibition by the coffee powder during the “infusion”stage, i.e. the stage that precedes the actual dispensing of the espresso coffee.


An espresso coffee machine, comprising: a pump which feeds water to a boiler for heating the water; a delivery pipe for drawing the water from the boiler and conveying it, via a three-way valve, to an infusion group in which coffee powder is infused and from which coffee is dispensed; and a pressure damping device located on said delivery pipe upstream of the infusion group which ensures that a boiler pressure is not applied abruptly to the coffee powder.
