Abstract: A closure system suitable for sealing a growler and dispensing beer under the influence of gravity and atmospheric pressure through a conventional tap faucet. A growler sealed with the closure system is held in an inverted position by a support system. The closure system is lower than the body of the growler and is connected to a conventional tap faucet. The closure system includes a cap with a manually operated valve. The valve rotates from a closed position to an open one, which opens two channels in the cap: one to conduct beer from the growler to the tap and the other to conduct ambient air into a collapsed bladder—which is an integral part of the cap—when the tap is opened to dispense beer. The collapsible bladder expands into the growler when the beer is dispensed to take up the volume vacated by the beer. The closure system and the support can be included in a kit, alternatively each component can be packaged as a stand-alone item.
