A pad holder of a coffee maker for making coffee with a foam layer on top includes a stud plate having studs for supporting a coffee pad containing ground coffee beans and an outlet opening for delivering coffee extract. Studs in the direct vicinity of the outlet opening are arranged in a circle, where surfaces of the studs form a circular directing surface. During operation of the coffee maker, a flow of coffee extract enters a space encompassed by the studs via channels between the studs, and is put into rotation as a result of interaction with the directing surface. Consequently, the coffee flow enters the outlet opening in a rotating condition, causing the outlet opening to deliver the coffee as a spray of fine droplets, from which the foam is created. |
