Let's see... how do we like our beer? Cold? Fresh? Carbonated? The Drink Tanks Growler ($65 and up) is designed to ensure all three. Crafted from lightweight, doubled-walled stainless steel, it's designed with a cap and bale sealing system that keeps your brew fresh and cold. As for the latter part, it also plays nice with a $30 keg tap cap lid that locks in place of the standard lid, and offers a place to inject CO2, a release valve to prevent overfilling, and a tap hose that lets the whole thing serve as a portable keg. If that sounds familiar, it probably should — but just remember that your current growler probably isn't made to keep beer cold, so if that's something that you're searching for, this is certainly worth a look.
