How big is a big bottle? 40 ounces? 64 ounces? How about a whopping 128 ounces? That’s how big the aptly-named DrinkTanks Juggernaut Insulated Beer Growler and Water Bottle is. At 128 ounces, the DrinkTanks Juggernaut is capable of carrying a full gallon of your favorite beverage (or meal) inside its vacuum insulated stainless steel walls, where it is capable of remaining cold for up to 24 hours or hot for up to 12.
The Juggernaut is truly a sight to behold. It dwarfs the huge 64 ounce growlers which previously seemed so massive. DrinkTanks also offers much more than size: with their nifty Keg Cap Accessory, the DrinkTanks becomes a super portable keg capable of dispensing beer at the press of a lever where-ever you go.
In this review we’ll be taking a look at both the DrinkTanks Juggernaut and its Keg Cap. We’ll explore how this bottle manages to be as versatile as it is massive.
Getting To Know The DrinkTanks Juggernaut: Bottle & Keg Cap Testing
Right out of the box, a DrinkTank is an impressive sight. Absolutely gigantic, our Juggernaut looks like the big brother of every stainless steel bottle we own. The really big brother: at 128oz, it is literally twice as big as the largest water bottle (the 64oz growler) that you can readily find available at most outlets. As far as the bottle goes, it is definitely of high quality construction, justifying its high-end price tag.
Manufactured with 18/8 food-grade stainless steel and double-wall vacuum insulation, DrinkTanks offer quality insulation. In our testing, the Juggernaut stood up to its claims of 24 hours cold or 12 hours hot. During our chilled ice water test where we left the DrinkTank Juggernaut sealed on our countertop for 24 hours, we found that although the ice had melted after 24 hours, the water was still refreshingly cold. In the heat testing it actually outperformed its advertising, as our coffee was still too hot to drink after 12 hours.
The lid of the DrinkTank seals with some help from two stainless steel clamps. You set the heavy, stainless steel lid into place, then position the bars of the clamp and fasten for an extremely tight and leak-proof seal. The design of the DrinkTanks lid (not the Keg Cap) has a 100% stainless steel system which ensures the bottle’s contents never touch anything but high food-grade stainless steel. This completely eliminates any worry of leaching or plastic contact. While the lid does incorporate some plastic gaskets, the design of it makes sure the gaskets do not touch the contents.
Your Portable Keg – DrinkTank As A CO2-Charged Beer Growler
While beer certainly isn’t a primary focus here at Hydration Anywhere, we certainly enjoy a pint now and then. The DrinkTanks Juggernaut is a massively versatile bottle, so it is good for whatever you want to carry in it – water, coffee, tea, hot soup, beer. Beer growlers are a fantastic way to enjoy some cold beer in locations where refrigeration is in short supply. More than likely, your favorite local microbrewery is happy to fill your growler for you, letting you enjoy delicious craft beers straight from the tap without being chained to the bar.
We don’t live in the best location for popping over to the local brewery, so although there is one in town, we have yet to fill our DrinkTank from anything but bottles. While beer aficionados will probably find this act blasphemous, the situation arose where we wanted some cold beers at the end of our long hiking/camping trip but we weren’t about to carry a whole cooler along just to enjoy a few frosty pints at the end of the night. Instead, we opted to test out the Juggernaut and its Keg Cap.
This was our second encounter with just how huge the Juggernaut really is. At 128oz, a complete six pack of beer (72 ounces) just gets us a little over the half-way full mark! So we bought two six packs and began filling it up. According to DrinkTanks’ instructions, you should leave at least a pint (17oz) out of the bottle before charging it with the CO2 to use the keg tap. So we poured in about 8.5 beers for 102 ounces, leaving a little wiggle room. That’s a lot of beer!
Let It Flow: Charging and Using the CO2-Powered Keg Cap
Once we figured out how it worked, using the Keg Cap was remarkably easy. We might recommend that DrinkTanks includes a little instructional pamphlet, as it wasn’t entirely self-explanatory at first. However, we found a very helpful video (see below) which demonstrated just how incredibly simple it is to use the Keg Cap.
All you have to do is take one of the two included CO2 cartridges and screw it into the included injector. You then simply press down on the injector on the Keg Cap’s valve to charge the bottle for use. It only takes a very brief press to get the bottle adequately charged. It is easy to overdo it – the first time we did it, it got too pressurized and released some pressure from the valve as soon as we took it off.
Although over pressurizing it might have changed the taste of our beer a bit, we decided to pour one out for testing as soon as we had charged it up. It came out pretty frothy, but after settling was exceptionally delicious. Pouring beer from the spout is easy, although it is important to note that is is a bit leaky after you’ve finished a pour. Be sure to hold it over the glass for a few seconds to catch any drip after you’ve released the pour lever. Still, even with this in mind, it seems to surprise us every time and manage to drip a bit.
The Ultimate Field Test: Hiking & Camping With the DrinkTanks Juggernaut
When full, the Jugeernaut is heavy. Empty it weighs about 3.6 pounds. If you filled it to maximum capacity, you’d be adding an additional 8 pounds! 11.6 pounds is quite a bit of weight to haul, no matter how delicious and alcoholic the contents might be. As we prepared for camping, we managed to pack the Juggernaut into a giant camping backpack, but we had to pack around it and make a lot of accommodation. We looked into removing the handle, but learned that while possible, doing so voids the lifetime warranty included with every Juggernaut. In general the handle is quite useful, as the bottle would be incredibly unwieldy without it, but for packing purposes the massive handle took up quite a bit of extra space.
Although it was a bit cumbersome, once it was packed away we didn’t even really notice the Juggernaut until nearly 16 hours later when we reached our campsite. After setting up camp, we decided to bust out the Juggernaut and some insulated tumblers to pour a few pints from the Juggernaut. Slapping on the Keg Cap, we pressurized the bottle and poured out a round of delicious beers. To our delight, they were still nice and refreshingly cold. We had taken the extra step of giving them plenty of time to chill before filling the Juggernaut up the night before.
As soon as we had enjoyed about half of our beers, we were definitely celebrating our decision to bring the Juggernaut along with us. Despite its bulk, it is fun to use and does a great job of storing and dispensing your beer. We found that we needed to recharge the bottle several times before we had drained the beer. But overall, we didn’t even expend an entire CO2 cartridge, which DrinkTanks says are good for 3-5 growler fills. If they do last 3-5 growler fills, this is a decent value, with replacement packs of 6 cartridges costing around $16.
The Biggest Bottle
Without a doubt the DrinkTanks Juggernaut is the single biggest growler bottle we’ve ever reviewed or owned. It may actually be the largest bottle available on the market, as it claims in its advertising. We even gave it the honor of ranking among our Best Bottles picks, distinguishing it as Biggest Growler Bottle in Best Bottles 2017.
This gives the Juggernaut a particular distinction. Anyone who wants maximum capacity will end their search with the Juggernaut. It is just as big as you get. It backs up its huge size with a sizable wide-mouth lid providing enough clearance to easily admit large ice cubes or even hot chunky soups or any other meal that can make its way into the Juggernaut’s vast reservoir. The huge capacity combined with quality insulation make the Juggernaut immensely versatile and applicable for storing all kinds of stuff – and lots of it.
So despite the focus on beer which the Keg Cap brings along with it, we look at our Juggernaut as a massive multi-purpose container only limited in utility by our imagination! The Keg Cap just provides a helpful suggestion and a neat, novel, and useful utility with its ability to help preserve and pour delicious tasting beers in unusual locations.
One challenge the size of the growler bottle brings with it is cleaning. You’ll definitely need some kind of bottle brush to get any scrubbing action in the interior of the Juggernaut. While that is typical enough for water bottles, what is unusual is the huge size has made it pretty much impossible to wash my Juggernaut in the sink. Instead, I’ve had to take it outside and use the garden hose to get it properly cleaned!
Too Big? Try Half-Size
If you like the features of the DrinkTanks Juggernaut and its Keg Cap but aren’t too excited about having a huge bottle that holds an entire gallon, you might be excited to learn that DrinkTanks also offers a bottle in a traditional growler size. Just like the Juggernaut, the smaller model is fully compatible with the Keg Cap since it uses the same type of lid and fastening system.
Traditionally, a bottle referred to as a “growler” tends to be 64 ounces. This was the criteria we used when we reviewed growlers for our Best Insulated Growlers article. While we haven’t had a chance to reivew the 64 ounce DrinkTanks personally, if it is simply a scaled down version of the Juggernaut (and why wouldn’t it be?) then it is likely to be a high quality growler.
Conclusion & Review Summary
Aside from having the distinction of being the biggest bottle you’re going to find anywhere, the DrinkTanks Juggernaut is a well-constructed, well-designed, and extremely useful product. It is massively durable, manufactured exceptionally well, and lives up to its advertised claims. This is good, because it has quite a hefty price tag exceeding $100 for the Juggernaut itself with the Keg Cap costing an extra ~$45. This is pretty pricey, but DrinkTanks has not skimped on the construction or design. They also include a lifetime warranty with every purchase, so customer support is backing up the investment.
Without a doubt something of a niche product, the Juggernaut and its Keg Cap are something that will likely have a vast appeal to certain people and little to others. If you have any use for a massive insulated bottle, the DrinkTanks Juggernaut is the massive insulated growler bottle to have.
Certainly in a class all its own, we have to give the Juggernaut high marks for its novelty, its quality execution, and its daring in being the biggest bottle in town. There is nothing else quite like it. We award it a solid 5/5 stars.
