MiiR growlers feature our double wall vacuum insulation technology which keeps your cold liquids chilled for 24+ hours or your hot things hot for 12 hours.


We have stripped away all threads normally required to close a vessel by designing an innovative clamp system that prevents leaks and nasty gunk found on threaded growler closures from beer residue.

Gives back

We believe in the simple idea of building amazing products that give back. We call it the Growler for Good as each MiiR growler provides one person with clean drinking water. We will even prove to you the impact of your purchase as each growler comes with a unique tracking braclet that has a printed ID number.


You can register this number on our website and in 6-18 months we will prove to you the exact water project you helped fund; complete

Premium stainless steel

We source the highest quality from Korea. Why? Because it's the best. Beer is also birthed in stainless steel, so stainless growlers are a natural.
