MiiR Insulated Growler
How would the perfect growler look? Probably a lot like MiiR’s Insulated Growlers. First, these 64-ounce vessels are made of vacuum-insulated double walled stainless steel, keeping cold drinks cool for upwards of 24 hours or hot drinks hot for about half that long. They’ve also got threadless clamp caps that clean easy, block all incoming light to keep beer fresher, are guaranteed leak-proof, and won’t shatter when dropped, unlike traditional glass growlers.
