This 64-ounce Wander & Rumble Beer Growler is designed and finished with the craft beer drinker in mind. Its design aesthetic has one foot in minimalist sensibility and the other foot in the functionality of classic, American spirit: each growler is crafted from food-grade single walled stainless steel with an ultra-light construction, allowing for easy transportation. The design is simple, yet sturdy enough to be handed down through generations - rather than disposed of at the end of a season. Deep threaded cap for long term carbonation and containment. Passivated interior for easy hand-washing.
