Best Thermos to Keep Coffee Hot Reviews

1. Stanley Classic Vacuum Bottle

Stanley Classic Vacuum Bottle took the market by storm the first time it appeared. And it has held its position as a top product in the thermos market especially for being a reliable product.

Known for its durability and reliable performance, this is the best thermos to use if you seriously want to keep coffee hot for over 12 hours.

This one is made of 18/8 stainless steel, a material well known for its durability and resilience. The green finish doesn’t just give this vacuum thermos the “feel good” look.

It’s more like a standard finish that adds to the overall strength of the thermos so that it can stand up to just about anything.

Because it weighs just 29 ounces unfilled, Stanley Classic Vacuum 1.1t is one of the most lightweight thermoses in the market right now.  In terms of capacity, it can hold up to 32 ounces full. Such an amount of coffee may not be enough for a big serving, but a liter is sufficient for a family of 3 or 4.

You will love this thermos because it can keep your coffee hot for 24 hours. And just in case you want your coffee served chilled, you can take advantage of the 120 hours of icing that this vacuum thermos offers.

Pros

  • A high quality thermos made of stainless steel
  • Can keep coffee hot for 24 hours
  • It’s cheap

Cons

  • The handle is a bit loose
  • The capacity may be small for some people

2. Thermos Stainless King Insulated Beverage Bottle

One of the best things about this thermos is that there is no limit to when and where you can use it. It’s a good choice for backpacking, hiking, cycling, and beach getaways, just to mention a few.

This thermos features a double-wall stainless steel build with zero air spaces between the two walls. With the air spaces completely stripped from the wall, what’s left is a vacuum space.

This is what helps to keep your coffee hot or cold for long. Moreover, the stainless steel used to design this unit isn’t just sturdy and resilient. It’s also durable and has a decent heat retention. And this thermos weighs just 2 pounds, which means it’s easily portable.

This thermos has a capacity of 68 ounces. So, it’s such a perfect size for serving a small as well as medium-sized family. The unit has a very decent heat retention. It ability to keep coffee hot for 24 hours means you don’t have to warm the beverage every time you want to drink. Simply cook once, pour in the thermos, and then keep it hot for longer.

Pros

  • This thermos has an excellent heat retention
  • It has a large capacity than Stanley Classic Vacuum Bottle
  • It’s durable because it’s made of high-grade stainless steel
  • Great design and it’s available in different colors

Cons

  • This thermos tends to lose its rate of heat retention over time
  • The exterior paint isn’t durable and is highly likely to start chipping over time 

3. EcoVessel PERK Vacuum Insulated Bottle

EcoVessel PERK Coffee Bottle is one of the well-made vacuum thermoses that you can use to keep your coffee hot. It features a premium grade 18/8 stainless steel construction.

This material makes the bottle durable, so you can use it for a very long time before you itch for an upgrade.

The bottle’ triple insulation is, by all means, its biggest selling point. At the very least, the insulation helps to keep your drink hot for up to 8 hours and cold of up to 36 hours. I wish the bottle worked the other way round.

But if you don’t mind keeping your coffee hot for just 8 hours, then this should suffice for you.

One of the things that I love about this vacuum insulated bottle is that it’s versatile. It’s not just a unit for keeping your coffee hot. You can also use it to keep water and tea hot or cold. And if you prefer to drink some fruit infusion hot or cold, you can use this bottle to optimize the warmth.

Although this vacuum bottle doesn’t feature a carrying handle, it’s still lightweight enough to carry in your hand. Plus, it’s compact, so it should take a very small space in your backpack.

Pros

  • It’s BPA free with no traces of liners or phthalates
  • Lightweight, hence easy to carry around
  • It’s a versatile thermos, able to keep coffee, water, and tea hot/cold

Cons

  • Keep coffee hot only for a short time
  • It would be better if it came with a loop handle

4. Zojirushi SM-SA60-BA Mug

I have been using Zojirushi SM-SA60-BA Mug for three months now. And I must admit that it lives up to the hype. The stainless steel build is the mug’s most impressive feature.

This construction ensures the strength and durability of the unit. So for the price you get a high quality bottle that will last for a very long time.

It has a capacity of just 20 ounces. In my opinion, a volume of 0.5 liters is big enough for one person, so you can bring your favorite coffee, regular or bold, with you wherever you go.

Plus, this mug is downright lightweight. It weighs just 7.2 ounces, which is nothing you can’t handle.

Even with the safety lock disabled, the closing lid should lock the bottle and stay tight until you loosen it yourself. But I recommend taking advantage of this lock because it helps to ensure that the lid doesn’t open accidentally.

Bold white coffee/tea has the tendency to stick on a mug’s surface during cooling. This makes the mug hard to clean. Fortunately, Zojirushi addresses this issue by adding a nonstick coating to the interior of this mug.  Thus, you can easily clean this bottle, no matter how many hours you’ve had coffee stored in it.

Pros

  • It comes with a manual, just in case you’ll need it.
  • Lightweight and versatile; you can use it for camping, hiking, backpacking, road trips, or even for office.
  • There is an air vent on the mouth piece for smooth flow of coffee
  • Keeps coffee hot for at most 24 hours

Cons

  • The capacity may be small for some people

5. Contigo AUTOSEAL West Loop Travel Mug

Contigo is a household name that has been in the limelight for ages. And it’s still a popular contender in the market because it designs the best thermoses that keep coffee hot and cold for hours.

The AUTOSEAL West Loop is their one such well-designed options. Because this travel mug is lightweight, you can easily bring it with you wherever you go.

As much as this model is a popular option in the market, and apparently Amazon’s current best choice in the travel mug category, it doesn’t have the best heat retention. To be clear, it can keep coffee hot for just 5 hours and cold for not more than 12 hours.

This may be fine for some users. But clearly, the temperature optimization isn’t as good as that of Stanley Classic Vacuum Bottle.

The auto seal technology may not be this mug’s strongest selling point, it still plays an important role nonetheless. After all, you don’t want your coffee spilling from the mug, especially when it’s in your backpack. Auto seal locks in your beverage in the mug well, so you never have to worry about spillage. 

Pros

  • This coffee mug is spill proof
  • It has a capacity of 20 ounces, which is enough for a solo user
  • Made of high quality stainless steel for strength and durability
  • Available in over 20 different color options

Cons

  • Doesn’t have the best heat retention
  • Can keep coffee hot only for a short time
  • It’s a bit costly than some similar mugs with the same functionality  and level of performance


Different people have different needs when it comes to heat retention. Some people only want to keep their coffee hot for just a few hours, which make a mug like Contigo AUTOSEAL West Loop a good option. Others like to keep coffee hot for a long time, and, as such, Stanley Classic Vacuum Bottle can be a good choice.
