The Pressurized Growler Keg from GrowlerWerks acts like a mini pressurized keg, complete with tap for an easy pour. It’s made by beer lovers to help folks like them enjoy fresh-tasting craft beer at home. An integrated CO2 system in the growler keeps beer carbonated for up to two weeks after you fill it—you can set the pressure you want by turning the dial. A carbon dioxide regulator cap holds CO2 inside and keeps oxygen out. Beer on the go stays cold thanks to double-wall, vacuum-insulated stainless steel, and an external pressure gauge and sight glass help you stay on top of what’s going on inside.
