Abstract

A method for producing crema in a coffee vending machine that has a flow-through heater for heating water and that is charged with substrate capsules which include a Venturi nozzle for crema production. The method includes a) heating the water in the flow-through heater; b) brewing ground coffee using the heated water in a brewing chamber in order to produce a coffee drink; and c) producing crema by mixing the coffee drink with a gas in the Venturi nozzle. In step c), at least one of two volumetric flows of the coffee drink or the gas is increased in the Venturi nozzle during a predetermined time interval.
