A faucet (1) serves for tapping of a liquid, e.g. beer from a container, in which the liquid is under pressure of a gas, e.g. CO2. The faucet comprises a casing (2) with an outlet duct (26) and a valve plug (7) placed in this for closing the faucet. In the stream direction, before the valve plug, there is freely, axially slidable in the outlet duct for at least a predetermined stretch, placed at least one resistance body (30) with a smaller cross section across the stream direction than that of the outlet duct. Thereby the dispensing process can, by alterations of the conditions in which the liquid, e.g. beer, is dispensed, automatically be regulated in such a way that the predetermined foam degree will continue to be present, that is the relation between foam and liquid.
