The GrowlTap's ability to turn a standard half-gallon growler into a beer tap is undeniably cool, but that's only half the appeal. GrowlTap's CO2 system prevents oxygen from aging, and eventually spoiling, your beer after to you pop open the cap. Instead of deteriorating after a few days, an opened growler will stay fresh for a month with GrowlTap. [$45; growltap.com]
