Abstract

A method for producing a beverage using a portion pack including a container made of filter material for containing an extraction material, and a supporting body which encloses the container. The method comprises the steps of: placing the closed portion pack into a filter vessel; opening the container of the portion pack on an upper side and increasing the internal volume of the container by at least 50% compared to the internal volume in the closed container; and applying water to the extraction material for beverage preparation. The portion pack comprises at least one folding edge on the supporting body about which a flap can be pivoted in order to increase the internal volume of the portion pack when opening.
