There’s not much room for innovation in the growler market. It’s a jug that holds beer. Simple. Turning one into a mini keg (like The TapIt Cap we recently featured) is the one smart move we could think of to help out the standard growler. Drink Tank Growlers are another solid option if you want to keep the beer in your growler fresher, longer. Made from lightweight double-walled stainless steel, the Drink Tank Growler can be fitted with one of two caps. The first is your standard wire bale cap and the other is a keg tap (tack $30 on to your order). It also comes with a convenient handle so you don’t have to cradle your booze like a baby, and you won’t have to worry about pounding that craft brew within a day of popping the top (with the keg top of course).
