Believe me, there is nothing worse than filling up your growler with Boneyard RPM in Bend, only to make the drive home to San Francisco and find out the beer has gone completely flat. And while a standard 64 ounce growler is great for personal use, what if you want to have a few friends over? Cold, fresh, carbonated, and more than enough to share–this is the promise of the new DrinkTanks oversized growler with auto-regulating keg cap.
