MiiR 64oz Insulated Stainless Steel Growler Review

MiiR Insuated Stainless Steel Water Bottle Review PhotoHydration isn’t always about clean water! Although, we admit, it usually is. But sometimes you want to to pour yourself a nice, refreshing, ice cold beer. And sometimes you want that same beer to still be ice cold 24 hours after you poured it. It’s in times like those that you would want to have the MiiR 64 Ounce Growler. Weighing in at 1.9 pounds and with a price tag around ~$55, the MiiR Growler is a pretty substantial bottle.

Featuring double-wall vacuum insulation, the MiiR is the perfect vessel to keep your beer frosty – and in no short supply. Of course, the stainless steel MiiR doesn’t discriminate, and functions equally well no matter what you decide to put it in: be it a beer, a smoothie, or just a sizable container to carry your ice water in while hiking, the growler’s insulation performs admirably.

Although the MiiR Growler made our list of Best Insulated Growlers, we thought we should give the particular product a bit more attention, so we’ve put together this in-depth review to help you get to know the MiiR Growler.


Staying Frosty with the MiiR Growler

Stainless Steel MiiR Growler In Use Pouring BeerWhile staying cold might be the main draw for beer lovers, the MiiR’s double walled vacuum insulation manages to not only keep your cold drinks cold for over 24 hours, but also keep your hot drinks hot for 12 hours! That means you could fill it with cold beer for your camping trip on Friday morning, and that beer will still be chilled and ready for you on Saturday night. After you’ve downed your beer, you can brew up some coffee and pour it into the growler to still be hot and ready to drink in the morning. Hallelujah! Not only that, but because of its vacuum sealed nature, as long as you keep the lid sealed and you’re not sneaking swigs here and there, your beer will remain carbonated! When you and your friends finish up the last chilled can of brew around the campfire or on the fishing boat, you can be the target of all their jealous rage with 64 ounces remaining, cold as can be.

The double walled insulation also means that the MiiR Growler doesn’t sweat. That’s right, no condensation, so it’s easily stashed in your backpack without needing to worry about getting everything else soaked. The 18/8 medical grade stainless steel construction insures that there will be no metallic taste to your ice cold beverage, as stainless steel is completely non-leeching and an ideal container material. Easy to clean and superbly durable, stainless steel is one of the best options for growlers or water bottles of any size.

The Many Uses of a MiiR Growler

MiiR Growler and MiiR Tallboy In Use At BeachBut it’s not just for keeping the colds cold, it can keep things piping hot for over 12 hours. Anything from hot tea to fresh soup! Combine this with the fact that the MiiR Growler is a 64 ounce gargantuan, you open up some real possibilities. That could be over four bowls of soup kept heated and fresh on the go for over half a day. Or the hot cup of tea you want at the end of the trail without having to build a fire.

The lid on the growler was a little unintuitive at first, but I learned to love it over the course of using the growler. Incorporating a flip-top which clamps down to form a leak proof seal, the lid manages to be both easy to open (once you get used to it, anyway) while also totally leak proof. While I did struggle with opening it a bit, after a few times it became second nature to pop the lid open to get a drink.

The 64 ounce capacity is something of a blessing and a curse. While we wouldn’t have it any other way than maximum storage, it does mean it can be a bit hard to work with the MiiR growler if you’re taking a drink. If you’re filling the MiiR Growler up with intent to share, it might be wise to bring some extra drinking vessels. MiiR actually makes some matching stainless steel insulated cups which are perfect to accompany the growler, such as the MiiR 16oz Tall Boy or the 16oz Stainless Steel Pint Cup.

Another minor gripe with the MiiR is its opening. The mouth is somewhat narrow, which can make getting larger ice cubes a bit tricky. But the opening is not so small as to make this a serious issue.

A Conscious, Charitable Buy


After hearing that for each MiiR Growler purchased MiiR provides one person with clean drinking water for 1 year, it warmed my heart for over 12 hours. But seriously, how great is that? According to Water.org 1 in 10 people lack access to safe drinking water. Anything you can do helps, and the fact that MiiR offers to help people in need each time someone buys one of their outstanding products is the cherry on top. The Growlers also include an “Impact Bracelet” which has a code you can use on MiiR’s website to track exactly what your individual purchase has helped accomplish.

It even helps the planet by reducing waste in the form of disposable bottles, directly contributing to lowering pollution. Of course, this is a property not unique to the MiiR bottle, but any reusable water bottle, and hopefully the reason why you’ve already sworn off bottled water!

Review Summary

MiiR 64 Ounce Growler in BlueThe MiiR 64 ounce Growler is a great buy. Not just for me or you, but for humanity. I’d hope that their sales encourage other companies in charitable endeavors as well. Aside from helping people in need, getting a MiiR Growler would be doing yourself a favor. It does it’s job extraordinarily well, and is great for bringing beverages (Or even soup!) to work, to a campsite, on a boat, or just to the backyard and consuming them as should be consumed.

The MiiR is a handy thing to have around. Toss it in your car full of water and know you’ve always got a way to hydrate on the go. Include it in your hiking gear as your main vessel for water – or fill it with a refreshing beer to enjoy at the end of the night. Coffee, soup, tea, a smoothie, a milkshake, or a margarita: your imagination is the limit.

Stacked up against other growlers, the MiiR is well-manufactured, made from quality materials, competitively priced, and features an awesome lid design which is both practical and leak-proof. The MiiR is great. In fact, we think it is one of the best insulated growlers on the market.

We award the MiiR Growler a solid 5/5 stars.
