While there are plenty of guys and gals who could finish off a 64 oz growler in one sitting, not everyone can achieve such a feat. If you've ever owned a growler, you know that its one downfall is that the beer immediately starts to degrade once you open it. So, if you're a craft drinker who likes to get the most out of your brew (so, everyone), check out The TapIt Cap. This ingenious accessory easily transforms your growler into a mini keg by making sure it stays fresh and carbonated. Because there is nothing worse than flat beer, nothing.
