We understand that anyone starting out on their coffee journey is faced with what seems like a mountain of equipment and paraphernalia to purchase.

You can even decide to dismiss the coffee scale, the gooseneck kettle, and the siphon coffee maker, but what do you do when you want that first-class coffee on the go?

Well, coffee thermoses allow you to keep your hot coffee nice and drinkable even if you’re challenged with a dull commute or you’re out hiking for hours. Equally, these thermoses will keep your iced coffee or cold brew cooler for longer. Or if you’re a mate drinker and you are considering buying an ideal thermos, the following thermoses will let you have that delicious mate anywhere and anyplace.

Now, we’ll be reviewing the best and most reliable 11 options at your disposal. As usual, we’ll also include a brief and pointed description so you can see at a glance what you need when you’re buying these coffee thermoses.

Last but certainly not least, we have another entry from the incomparable Hydro Flask. The lifetime warranty offered is proof of reliability and trustworthiness. But what makes this mug so good?

The 16 oz. capacity is adequate for a large coffee. If this doesn’t seem like the best fit, you can find this flask in a 12oz or 20oz variant. Overall dimensions of this 16oz model are 2.9 x 2.9 x 7.5 inches so you’ll get a small and squat flask despite that generous capacity.

Multiple colors allow you to find something ideal for your liking.

Since it’s dishwasher-friendly, you won’t have any inconvenience with any clean-up.

If you want a travel mug that’s built to last for years, then you should invest in the Hydro Flask and kiss goodbye shopping for coffee thermoses on a yearly basis.

  • 16 oz
  • capacity with a wide mouth
  • Safe to pop in the dishwasher
  • Lifetime warranty for complete peace of mind
  • Quality control is questionable

Bottom Line: If you want a sleek and compact travel mug that’s a snap to keep clean, try this Hydro Flask.

Now putting our reviews aside, it’s time to focus on the key things you should consider when comparing coffee thermoses.

II. Things You Should Consider

Check out these factors when it’s time to purchase a thermos and you will maximize your chances of finding the right flask for you.

  • Capacity
  • Insulation
  • Lid
  • Ease of Use
  • Washability
  • Design and Color Schemes


One of the first things you need to clear up is what size of thermos would make the best fit for you.

To determine this, you should ask yourself a few questions:

  • Do you need to carry the flask for long periods of time?
  • Are you the only person who will be using it?
  • Are you using the thermos outdoors?

If all you need is a small mug of coffee or a travel-friendly container for a short drive, you can easily get away with one of the 12 oz. or 16 oz. flasks.

Maybe you work from home and you don’t want to endlessly run to and from the kitchen.

Or perhaps you have a lengthy commute or you might spend long days hiking.

In all of these situations, it would make sense to get a travel mug that’s still compact enough to carry but robust enough as well when it comes to durability.

There’s no right or wrong answer here. All that counts is establishing the right size for you.


Once you have chosen the appropriate capacity, you should check which thermos on your shortlist stands up on the insulation front.

Regardless of whether you opt for a stainless steel thermos or a glass one, the crucial thing is that it’s properly insulated and will keep that coffee either piping hot or ice-cold for as long as you need it.

The best thermoses have double-walled insulation and they’re vacuum-insulated.

Cheaper plastic thermoses might be serviceable for short-term use, but they’ll struggle to keep your drinks hot or cool for more than a couple of hours.

So, you should honestly examine your intended use so you’re not duped by the marketing hype.

While it might sound attractive, do you honestly require your coffee to stay warm for 24 hours? In what kind of scenario you could leave your coffee without drinking it for that length of time?

If you need a flask that gives you more freedom, whether you work long hours overnight, or you spend long stretches of time driving and unable to stop off for coffee, there are plenty on our list that delivers enviable insulation.


Not all lids are created equal, even those labeled as spill-proof.

Contigo and Zojirushi mugs both have stellar reputations on this front. Here at BestCoffee, we use travel mugs from both brands, specifically for the strength of the seals and their completely spill-proof nature.

Whether you want to store your coffee in your bag or in your pocket, looking for one with a great lid makes the difference between daily convenience and a nasty spillage.

As well as considering how the lid seals, you should also give some thought to how easy it is to clean. With the Contigo, for example, the lid is quite tough to keep completely spotless. Don’t be tempted to just clean these mugs out every once in a while either. You should blitz them thoroughly after every use to prevent germs and bacteria from gathering.

Ease of Use

Next up, you shouldn’t overlook how easy the travel mug is to use.

Here, you really need to personalize things to get the best fit. Think about where you’ll be using your mug, whether you plan to drink from it while driving if you need to carry it for long periods, and whether you’ll be drinking hot or cold coffee.

By getting particular and narrowing your purchasing decision down to focusing on only what you want from a thermos, you have a far stronger chance of finding the right one the easy way.


Now, not all travel mugs are easy to wash. Given the number of traps for germs and bacteria––especially in and around the lid––you should check whether the mugs on your shortlist are dishwasher-safe. We list this for each model we review so you can compare them and choose the best one for you.

Design and Color Schemes

While you won’t be shopping for thermoses primarily based on design, aesthetics is a bit important when it’s time to decide which thermos to get.

More importantly than the choice of color schemes are the bonuses such as a cap that doubles as a cup, or a carrying handle, or such as how easy it is to clean the inside.

Again, rather than seeking a one-size-fits-all solution, focus on what you want and don’t want in a travel mug to find the best one with ease.

Now, before we wrap it all up, we’ve assembled some of the most frequently asked questions we get about coffee thermoses here at BestCoffee.


1) Why should I bother buying a coffee thermos?

If you commute to work and want your drink to stay hot or cold on your journey, a thermos makes great sense. They also work well if you like sipping safely on coffee in the car or when you’re out camping or hiking. Even within the home, these mugs can be a convenient bonus, especially if you struggle with mobility.

2) What’s the difference between leak-proof and spill-proof?

Spill-proof travel mugs will automatically default to their sealed state. With spill-proof mugs, you need to physically close the mug to prevent spillage. Once closed, the spill-proof mug will perform the same function.

3) Are all thermoses dishwasher-friendly?

No, they’re not. Check and read the product description to see if it’s dishwasher-friendly or not.

4) How can I get rid of the smell in my coffee thermos?

All you need is some vinegar and hot water.

Pour just a bit of vinegar into the bottom of your flask then fill it up with hot water.

Put the lid on and then shake it up. Leave the mixture to sit for 30 minutes.

Empty it and clean it with fresh water.

Then, allow it to air dry.

Any offending smell should be gone.

5) Can I use bleach to clean my thermos?

No. Avoid all bleaching agents. If your thermos becomes stained, use baking soda and hot water as a safe alternative that should see off any discoloration. Alternatively, look for a dishwasher-friendly model.

IV. Conclusion

Well, if you started today with no idea about coffee thermoses or wondering why you might need one, then we’re sure that has changed now.

Anyone with an active lifestyle or with a simple desire to enjoy great coffee wherever they are would benefit from one of these insulated flasks. Whether you love hot coffee or iced coffee, you can keep it at its best for hours on end with one of these thermoses.

Now, before you head off today, we’d ask you to take a moment to bookmark BestCoffee. We’re here to bring you nothing but the best gear and the most reliable resources so you can become a home barista and avoid those crippling monthly coffee shop bills.

Grab yourself one of these coffee thermoses and witness how you won’t have the need to hit the coffee shop when you’re out and about. Take your favorite blend with you saving time and money while saving the environment.
