  • Patent number: 9066621
    Abstract: The present invention relates to an espresso machine or a fully automatic coffee machine having a grinder and an infusion device comprising an infuser and an infusion chamber, which is characterized by a volume-determining portion designed to determine the ground volume of a defined quantity of coffee powder ground by means of the grinder, a mass-determining portion designed to determine the ground mass of this quantity of coffee powder, and a calculation portion with which, on the basis of a predefined correlation, which is stored preferably in the calculation portion itself, between the grain size distribution and/or the degree of grinding of ground coffee, on the one hand, and the mass and the volume or a variable derived from these two variables, in particular the density, of ground coffee, on the other hand, there can be calculated from the determined ground volume and from the determined ground mass, the grain size distribution and/or the degree of grinding of this quantity of coffee powder.
