Unlike a standard glass jug growler—which loses carbonation within 24 to 36 hours after opening—a CO2-pressurized stainless mini keg (like the TMCRAFT 128 oz or GrowlerWerks uKeg) maintains positive CO2 headspace pressure and keeps oxygen out, preserving fresh draft carbonation for 2 to 3 weeks when refrigerated.
