The Ultimate 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.
The Growler also comes with double wall vacuum insulation, helping to keep your beer cold for hours.
This is the new improved MK2 model with new lid design. This new MK2 model is more robust and more reliable than the previous growler design.
Most screw top growlers struggle to hold the pressure required to keep beer fresh and carbonated. The Ultimate Growler comes with a spring wired lid capable of holding up to 40psi.
