Here’s a sneak peek of our lineup of top mugs that keep coffee hot!
If you know me, you know I love a pipin’ hot cup of coffee. None of this lukewarm crap that technically “passes” as coffee. When I finally resigned to the fact that I am a daily coffee drinker, I immediately needed to solve for finding the best coffee mugs to keep coffee hot.
Sometimes it’s because I’m commuting to work and won’t be able to dig into my freshly brewed cup for awhile. And sometimes I accidentally forget my coffee is even there (I KNOW!) because I’m in flow or deep focus for long periods of a time (it happens—usually when I’m loving my work).
Those, plus the fact that coffee flavors change as it cools, are factors that started my search for the best travel mug to keep coffee hot for hours.
After 12 years of coffee drinking un-ironically (high school was a weird time for me), I’m ready to share the best coffee mugs to keep coffee hot that I’ve found!
What to look for in a cup that keeps coffee hot
There are five main factors to consider when shopping for a coffee mug that is built to keep coffee hot.
- Insulation. Double walled or nothing, regardless if you choose plastic, glass, or stainless steel.
- Size. Do you drink 20+ ounces of coffee on a regular day or are you more of a one-cup kinda coffee drinker? Keep this in mind as you search for the right hot coffee mug for you.
- Durability. Accidents happen. Especially for families with young children, you might consider avoiding glass coffee mugs that keep coffee hot, for example.
- Ease of cleaning. If it can’t be tossed in the dishwasher, we’re probably not going to recommend it.
- Your commute needs. If you work from home, a spill-proof lid might not be essential. For those who walk, ride, or drive to their place of work, make sure you triple-check that the lid won’t accidentally become the demise of your bag contents.
5 mugs that keep coffee hot all day—or long enough!
The Foxlee household residents are big fans of double walled coffee mugs, not only because they look sharp and classy, but they work incredibly well as a cup that keeps coffee hot. Because of the double wall glass construction, each glass has thermal properties that help keep hot drinks warmer and cool drinks cooler.
As a bonus, they’re lightweight compared to their ceramic counterparts. The double walled insulation also means they’re easier to hold (the second layer of glass is cool to the touch) and they’re less likely to yield exterior condensation (sayonara, coasters).
You can practically keep coffee hot all day in Hydro Flask’s 12 oz travel coffee mug. Although the lid is not leak proof (for true commuters, their coffee flask is a way better investment), their signature TempShield insulation technology keeps drinks cold or hot when used with a lid. Similar to the Bodum double walled mugs mentioned above, Hydro Flask uses a double wall, vacuum insulated technology that guards the temperature of your drink.
This is a good mug to have in your kitchen if you work from home and need a cup that keeps coffee hot without a commute.
Klean Kanteen’s coffee mug is, hands-down, the travel mug that keeps coffee hot the longest—up to eight solid hours in my experience. It’s leakproof lid locks in the temperature from the get-go, so there’s no need to optimize for afternoon access to a microwave. It tastes just as good as a 3p afternoon-slump-energy-boost as an 8a necessary-wake-up-aid.
I generally prefer the locked lid design of the Hydro Flask travel coffee mug to Klean Kanteen’s twister, but I can’t deny that Klean Kanteen’s product works consistently as one of the best coffee mugs to keep coffee hot. Even if a slightly unsightly product can keep coffee hot all day, I’m here for it.
Also, how cute are all those colors?! Is it unreasonable to have a cup that keeps coffee hot as an accessory for every outfit…?
Here’s a secret: If you keep your coffee in a well-insulated coffee carafe, then every pour that follows will be kept hot!
Think about it. If you are planning to drink more than 8-12oz of coffee in a day, and your goal is to keep coffee hot all day, it’s better to keep the bulk of the freshly brewed coffee together in a well-insulated carafe and pour as needed.
We have a coffee carafe from Saint Anthony Industries that we love, but unfortunately is discontinued. Thanks to the addition of a silicone lid to further aid insulation, this option from Fellow Stagg actually feels like an upgrade as a way to keep coffee hot all day. We still love and recommend the double-walled coffee snifters from Saint Anthony’s as the vessel of choice when pursuing this method of keeping coffee hotter, longer.
Smaller pours + hotter coffee diminishes the likelihood of your coffee cooling too quickly. Hot mug win!
5. Contigo Autoseal (16 or 20 oz)
There’s a lot of hype over Contigo’s Thermalock system—and for good reason. We’ve found that Contigo’s lid technology does the job to keep coffee hot. If you’re looking for a larger container to tote your coffee-to-go, this budget thermal coffee mug from Contigo is a great option to consider—you can get it for as little as ~$12!
It’s a little too big for MY personal taste, but this travel coffee mug works perfectly when David and I are sharing one mug in the car for road trips, for instance!
Coffee mugs to avoid if your goal is to keep it hot
Do ceramic mugs keep coffee hot? Sort of. Ceramic has less thermal conductivity than glass because its more porous, but unless your mug is double walled, you’ll still suffer from a ceramic coffee mug releasing heat too quickly (making your coffee contents cool faster AND harder to hold) than the suggestions above.
Similarly, “tin” mugs look ultra-cute and campy, but they fail when it comes to avoiding lukewarm coffee. Coffee mugs made of any other kind of metal are likewise not optimal for heat insulation. Single-walled metal a great heat conductor and thus the exact opposite of what you want. (“Your travel mugs are metal” you may object. But they’re not single-walled metal. Inside all of the above metal mugs look just like that double-walled glass. So they’re mostly air.)
Plastic is actually a very good insulator, on the other hand. The issue is that most of us have grown up (reasonably, in my view) at least a little skeptical of the safety of combining very hot water and plastics. When I’ve had plastic travel mugs (Stanley makes some nice ones) they’ve been pretty good at keep things warm. But plastic is prone to staining (not a great look) and sometimes does impart a bit of a flavor.
As a rule of thumb, no matter what material your coffee mug is made of, make sure it is double-walled and not single-walled!
