Beer-fau′cet.
For draining certain descriptions of beer it is desirable to foam it, which is done, when the beer has not life enough of its own, by means of a piston which ejects air along with the beer into the glass or pitcher. As the piston descends, air is ejected at the central aperture, mixing with the beer, which passes out at the annular orifice around the air-opening. |
