VERFAHREN UND VORRICHTUNG ZUM SCHÄUMEN DES BIERES IM ZAPFHAHN

So as initially to fill a beer glass (6) only with foam which after at least one minute settles to yield a quantity of beer sufficient to fill the beer glass (6), the beer, while travelling from the barrel to the outlet spout (4), is made to flow through at least two pin-hole apertures (8, 12). After flowing through each of said pin-hole apertures (8, 12) the beer flows against a baffle plate (10, 14), which results in the formation of carbon dioxide gas bubbles by controlled release of carbon dioxide. The strongly foaming beer flows from the outlet spout (4) into a beer glass (6, 6') in which it collects exclusively or almost exclusively in the form of foam. After at least one minute the foam settles to yield a quantity of liquid corresponding to the amount of beer required for the beer glass (6, 6').
