A system, method, and device to promote a compact and direct solution for craft breweries to distribute their products via kegs instead of using stainless steel and CO2 barrels, where a polymeric barrel containing an internal plastic balloon is used. This balloon is filled with beer, and, as it is filled the internal volume of the barrel is occupied, however, the internal volume is not fully filled by the balloon with beer.
