Best Thermos For Coffee (Keep Your Coffee Hot With These Flasks)

Wouldn’t it be great if you could enjoy home brewed coffee in the car, at work, or even out in the wilderness when camping? Now you can with the best thermos for coffee, no longer will you be limited to drinking your favorite coffee at home, grab one of these flasks and sip on your cuppa Joe from absolutely anywhere.

In a previous article “How To Keep Coffee Hot” we briefly talked about thermos flasks as being an option to keep your coffee hotter for longer. Since that article was published, a few readers have asked us which coffee thermoses we recommend, so as a spin-off from the previous article, we decided to write a full review of some of the best thermoses for coffee we could get our hands on.

How To Choose The Best Thermos

Not all coffee thermoses are equal, in fact, you’ll find that there is a huge variation in both quality and price when choosing the best thermos for coffee. If you want your coffee thermos to last through the daily barrage of knocking, commuting on public transport and thorough cleaning you’ll want piece of mind that the thermos you have chosen is up for the job.

To ensure your new coffee flask ticks all of the boxes we have briefly covered some of the best features that any coffee thermos should have to be a worthy companion when you leave home.

Does Size Matter?​

​When choosing the best thermos for coffee, you’ll quickly discover that there are many different sizes to choose from, with sizes starting at small 16-ounce thermos mugs up to larger 40+ ounce beasts that can caffeinate a small army, okay not quite but you get my point.

​The size of your coffee thermos boils down to what you will be using your flask for; are you drinking just for one, or are you sharing your coffee with others? Even if you’re not sharing I would recommend buying a coffee thermos that can hold more than one cup, a 16-ounce is a great size – let’s be honest when have you only had 1-cup!

​The best thermos for coffee is going to keep your coffee hot for almost all of a working day. So with a larger flask, you’ll be content knowing that you’ll have enough piping hot coffee to get you through that painful Monday in the office (the better-insulated flasks might even pour you a hot coffee on your commute home).

Thermos Construction

​Most of the best thermos flasks are manufactured from double-walled stainless steel, or sometimes plastic. Stainless steel is going to be the better option as far as we are concerned, and it will resist corrosion, rust, it will have no problem with both cold and hot temperatures and resists odor; plus it’s the best choice to hold up against the daily wear and tear of commuting to and fro from work.

Is A Handle Useful?

​Depending on the size of the thermos flask a handle can be extremely helpful, the larger the size, the harder it will be to hold (especially with cold hands) firmly. However, remember that a handle will make it a bit more difficult to slip snugly inside of your backpack so if you intend on taking your coffee flask with you to work a handle might not be as important than if you were sat around a camp fire with cold, numb fingers.

​With that being said some of the best thermoses feature a removable handle, providing you with the best of both worlds.

​Insulation Is A MUST

​Let’s be honest if your flask doesn’t keep your coffee hot then it’s pretty much useless. Insulation is a must when choosing the best thermos for coffee, luckily enough most of the better coffee flasks feature vacuum-sealed double-walled insulation. To put this into layman's terms for the non-techies, air is sandwiched between the outer walls of the thermos flask, when sealed the vacuum created will then remove air from in between the walls which in turn will virtually eliminate the convection process and temperature change.

​Cup And Lip

​On nearly all thermoses for coffee, the lids have been designed to also act like a cup and most of the better thermoses will feature an insulating cup that will keep your coffee hot while at the same time not burning your hands.

​You will also find that the pouring lip will vary from thermos to thermos, some will be a simple screw cap while some of the best coffee thermoses will feature a twist and pour function that will allow you to pour without having to move the stopper.

​However, it’s important to keep in mind that the best coffee thermos should be able to fully come apart for deep cleaning, especially the pouring spout and cap sections to avoid the accumulation of bacteria and old coffee residue. If the thermos can't be easily broken down into its different parts such as the rings, stopper, spout, and lid, we recommend that you look for one that can.
