Features:- NEW IMPROVED MORE RELIABLE LID SEAL- 304 Stainless Steel- Double Wall Vacuum Insulated- Sprung wire lid- Optional tapping head sold separately (Growler Drafto Kit) This system doesn't include the regulator, growler Tapping Head or 16gram bulbs. These can be purchased separately with the links below and you can turn this growler into a portable keg system. New improved MK2 Model with New Lid Design. This new MK2 model is more robust and more reliable than the previous growler design. These are also compatible with the Drafto kit that we sell. This Growler is made from 304 Stainless Steel that is completely impervious to oxygen and sunlight (UV) meaning your precious amber liquid is in the absolute best storage container possible. Unlike other growlers this growler comes with double wall vacuum insulation to give you insulation like no other growler. So forget taking the esky, this baby will stay cold for hours. 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.
