Best Thermoses for Coffee in 2021 - Reviewed
Zojirushi specializes in making contemporary, beautiful and useful products. They have more than 100 years of experience under their belt. They started off with hand-blown vacuum bottles so it’s totally on-brand for them to come back and make some seriously sweet steel mugs.
This particular Zojirushi Steel Mug pays special attention to temperature. Able to keep your coffee at 189 degrees for 1 hour and 160 degrees for 6 hours. When it comes to keeping things chilly, it can hold cold temps as low as 46 degrees.
How does the Zojirushi manage this?
Using vacuum insulation, of course. In between the inside and outside layers, there’s a layer of aluminum and copper tightly wrapped around the outside of the inside layer. The aluminum or copper reflects heat (or cold) back in, minimizing how much the temperature can change.
This mug is sleek and comes in a variety of beautiful colors, so it fits with any aesthetic. With its lightweight design and pictograph lock, it’s easy to open when it’s in your hand, but If you’re throwing it in your bag, it has a lock feature to keep it from getting knocked open. All this means that the Zojirushi Steel Mug can easily be the newest accessory to any daily commute.
The Contigo West Loop is a staple for commuters—and it’s no mystery why. Contigo has made quite a name for themselves in the on-the-go lifestyle industry, they operate entirely around conquering everyday problems — like coffee spills.
Contigo’s unique AUTOSEAL technology makes the West Loop travel mug leak and spill-proof, and helps keep your hot coffee hot for up to 5 hours and your cold coffee cold for as long as 12 hours. There’s also a lock feature to eliminate even the possibility of pressing the button inside your bag and releasing any of the heat—or god-forbid, the coffee itself.
Top it all off with the fact that it’s dishwasher safe, sleek, and comes in a variety of designs, colors, and sizes, and, well, it’s clear there’s a Contigo AUTOSEAL West Loop for everyone. It’s even been named the official reusable water bottle of Coachella 2020.
The Thermos brand has become synonymous with insulated travel products, and there’s quite a substantial reason for that. Sir James Dewar invented the vacuum flask, a significant breakthrough in scientific instruments. In 1898, Dewar hired a professional glassblower, Reinhold Burger, to make his vision commercially available.
Reinhold Burger and his business partner, Albert Aschenbrenner, came up with the idea to encase the vacuum flask inside a metal casing, after which a local resident topped off this invention with the name we all know today: Thermos. In Greek, THÉRMĒ means heat, making it absolutely perfect as the moniker for this vacuum bottle.
An American businessman caught wind, and the rest is history.
Today, Thermos is still using the same vacuum sealed technology as more than 100 years ago, but with some modern advancements, like the stainless steel interior and exterior. Cool to the touch with a sweat-proof lid, it also fits most car cup holders (a must-have).
Ideal for the office and on-the-go, the Thermos Stainless King is top-rack dishwasher safe and comes in a variety of colors for every preference. It’s even great for tea drinkers thanks to the integrated tea bag hook!
Hydro Flask is a newer player in the insulated travel mug industry, but it’s made waves since its founding in 2009. Their goal is to make an active, joyful life on-the-go easy with everything they produce. On top of that, their charity, Parks for All, supports the development, maintenance, and accessibility of public green spaces to encourage healthier, happier lifestyles everywhere.
From the office to the gym to the campsite, the versatile design of the Hydro Flask really does work. Available in a variety of eye-catching colors, there’s a Hydro Flask aesthetic to match everyone’s individual flairs.
Six Whole Hours
Whether you drink your coffee hot or cold, the Hydro Flask can help keep your coffee at the right temperature for hours — seriously, the Hydro Flask can keep your cold brew cold for up to 24 hours. When it comes to keeping your joe hot, the Hydro Flask can keep your coffee hotter for longer than any other mug on this list — six whole hours!
It’s all thanks to the innovative TempShield™ insulation. Top it all off with the fact that this beaut can fit under most coffee brewing system spouts, can fit any of three types of lids, and boasts a lifetime warranty. #sold
Stanley, much like Thermos, is another long-time player in the vacuum bottle game. Where Thermos offers a camper vibe, the Stanley company is closely associated with the rough and rugged worker life.
Founded in 1913, William Stanley Jr. was the first to fuse vacuum insulation with the all-steel body that we know and love today. The Stanley Classic pays homage to the original look and feel of Stanley Vacuum Bottles—the larger body and the cup-functioning lid topped off with the old-school lunchbox-style handle are truly classic.
Available in three sizes (1.1qt, 1.4 qt, and 2 qt) the Stanley Classic is a favorite among coffee connoisseurs and adventurers. The largest size is able to keep your coffee for 32 hours. Did you read that? Thirty-two full hours. Don’t even get me started on cold. It can keep your cold brew chilled for 160 hours. One hundred and sixty hours.
That’s more than six and a half days.
Even the 1.1 quart boasts some impressive numbers, able to keep your caffeinated joe heated for 15 full hours, cold for 60. It’s not even the least bit surprising why this old school number is a fave. If you’re looking for performance that can’t be outdone by anyone else, it’s the Stanley Classic.
If you’re looking for a coffee thermos that can handle coffee on the go for everyone, this ENLOY 61 oz. stainless steel option is exactly the vacuum thermos to handle it. Heavy duty and boasting two cups for the lid, the ENLOY is as easy to pour as it is to carry thanks to the included strap.
The patented vent system and splash-proof spout make sharing a breeze, and there’s even a bottom compartment good for storing sugar, tea bags, and more. To keep contents warm, there’s a triple-sealed lid and a double-liner vacuum.
ENLOY may be a relatively unknown name compared to options like Thermos and Stanley, but this large, rugged steel vacuum thermos should definitely be a contender for campers, picnickers, and anyone up to actually share their coffee.
YETI may feel like another long-time player in the vacuum insulated bottle game, but Roy and Ryan Seiders didn’t found YETI until 2006. Despite that, this outdoorsy brand has become well known for its coolers, gear, and, of course, drinkware.
The YETI Rambler is 100% spill-proof, features a no-sweat design, and allows for flexible usage thanks to its unique lid. Give the top a half twist until it clicks and sip from anywhere to gain access to your delicious joe. It’ll stay warmer for longer, too, thanks to the double-walled vacuum insulation!
Pick your favorite color from their wide variety and don’t worry about any extra work because you’ve bought a fancy bottle—the Rambler is dishwasher safe!
If you’re the type that loves a good dramatic flair to everything you own, the Iron Flask Vacuum Insulated Stainless Steel Mug will definitely catch your eye. The powder coat exterior design comes in everything from classic black to neon green, from ombre white to black to a tequila sunrise.
The newest to the game having been founded in 2016, Iron Flask is still in its early years, but they’ve already served 100,000+ customers and have some weighty goals of being a household name for being reliable and affordable. I think we can all appreciate that!
In an effort to curry favor in the market, the Iron Flask comes with three lid types so you can pick your favorite. Whether it’s time for caffeine or time to hydrate with some H20, there’s a lid best suited for the function. Not to mention that this bottle can keep hot things hot for 12 hours and cold things cold for a full 24—those are some impressive numbers from this fledgling company.
Plus, there’s a 100% money-back guarantee, so, no harm in giving this up-and-comer a shot.
Why should You get a Coffee thermos?
If you need a little more convincing about the usefulness of owning the perfect coffee thermos, it goes beyond portability. A quality thermos can be worthwhile for anyone who is looking to cut down on coffee costs. Bringing your own coffee to work from home can save hundreds or even thousands of dollars a year, and give you that same caffeine boost to get through your day.
Thermoses can also help lower your food waste. The coffee you don’t finish while getting ready can be easily transferred to a thermos so you can continue to sip it on your commute—instead of having to throw hot coffee down the sink, you can now enjoy it.
Bringing a reusable thermos to work can also be environmentally friendly if you’re opting to cut out your daily visit to the local coffee shop. Not only does a thermos keep your coffee warmer or cooler than a single-use paper or plastic cup, reducing paper and plastic waste is an important step in lowering our carbon footprints.
Here are some tips that will keep your coffee warm and your mornings running smoothly.
- Prime your mug by pouring boiling water in your mug 5-15 minutes before putting your coffee in to keep your coffee hotter for longer. Here is a video explaining how and why you should prime a thermos.
- Even if a travel mug claims to be dishwasher safe, washing it by hand with a bottle brush can help lengthen its life by protecting it from harsh dishwasher detergents. Daily use can make your tumbler susceptible to coffee stains. Here is a helpful video that shows how to remove lingering smells from steel thermoses.
Hopefully, answering those questions has narrowed down what type of coffee thermos you want. Here are some of our favorites so you can begin comparing and shopping!
The best coffee thermos for each person will vary based on individual priorities. I’d take the ENLOY on a picnic in a heartbeat thanks to its massive size, but the Zojirushi SM-SD48XA Steel Mug is a great option for the average commuter because of its sleek design and ability to keep drinks warm for hours.
On the other hand, if your coffee-warming needs are more suited for long treks outside, the Stanley Classic Vacuum Bottle would be a better fit thanks to its ultra-impressive numbers.
If aesthetics are important, the Iron Flask colors are dazzling.
Whichever coffee thermos you choose, just make sure it’s one you can envision yourself enjoying every day. Happy caffeinating on-the-go!
