Most screw top growlers struggle to hold the pressure required to keep beer fresh and carbonated. Our Ultimate Growler comes with a spring wired lid capable of holding up to 40psi. Wire sprung lids also have the added advantage that they act like a pressure release valve preventing damage to the growler. So if the pressure gets too high in the growler (ie. the product starts fermenting again) then the lid will pop up, release pressure then re-seal.
