Abstract: A method of preparing a short coffee beverage having a brewed volume of from 25 to 75 ml is provided. The method comprises: placing a coffee filter pod in a brewing chamber of a low pressure beverage brewing machine; passing a beverage medium through the pod to extract the roast and ground coffee; and producing a flow resistance through the coffee filter pod using a particle size distribution that leads to increased flow resistance and a pressure drop, wherein the coffee filter pod contains roast and ground coffee with a plurimodal volume distribution density with a first peak of from 30 to 60 microns and a second peak of from 260 to 330 microns, wherein the ratio of the volume of the particles in the first peak relative to the volume of the particles in the second peak is from 2:1 to 1:2.
