If you’ve ever gone to get your growler filled with sweet, sweet beer only to realize you won’t be able to get home and refrigerate it for quite some time, the MiiR Growler is for you. The double wall vacuum insulation will keep your cold beverage chilled for over a day (or a hot drink hot for around 12 hours). That means your beer won’t get ruined riding around in your car with you after your fill. The guys behind the MiiR Growler also ditched the threaded cap idea to avoid leaks that both cause you to lose beer and ruin its carbonation in the process. Plus, for every growler sold, they’ll provide one person with clean drinking water, so you’ll even feel better next time you drink up (wasn’t sure that was possible).
