A method for preparing a beverage suitable for human consumption and having a fine-bubble form a layer including delivering the beverage under pressure with at least one nozzle which is in fluid communication with the beverage unit for supplying the beverage to the nozzle such that the nozzle can generate a jet of beverage. The method further using a receiving unit into which the jet is directed for obtaining the beverage with the fine-bubble foam layer, said receiving unit being provided with a chamber with at least one drain opening for delivering the beverage with the fine-bubble foam layer and a jet impact member accommodated in said chamber and having a top that lies free from an inner wall of said chamber. The nozzle and the jet impact member are mutually oriented such that the jet hits against a portion of the top of the jet impact member, so that the jet after hitting against the jet impact member forms a mist of the beverage. The beverage with the fine-bubble foam layer subsequently leaves the drain opening. The method further involved use of a device constructed such that air can only be supplied to the chamber through the at least one drain opening and/or through an air supply channel which extends through the jet impact member into the chamber.
