Whether you’re commuting to the office or working from home, there’s no denying the convenience of using a thermos for your coffee. Not only does it allow you to enjoy your beverage on the go, but it also helps to preserve the freshness and flavor of your coffee for hours. When you brew your coffee directly into a thermos, you can be sure that it will stay piping hot without sitting on a hot plate and developing those bitter flavors that can ruin an otherwise perfect cup of joe.
And let’s not forget about iced coffee! With a thermos, you can take your favorite cold beverage with you and enjoy it all day long without the need to constantly add ice. Simply brew your coffee ahead of time and chill it in the fridge before transferring it to your thermos. The insulated walls will keep your drink cold and refreshing for hours, making it the perfect choice for a long day at the office or a fun outdoor adventure. So whether you prefer your coffee hot or cold, a thermos is a must-have accessory for any coffee lover on the go!

With their excellent performance, trusted brand names, and leak-proof design, you really can’t go wrong with any of these options.
Hot Coffee Thermos Test
Each thermos was preheated with hot top water while I brought water up to a simmer. Just for the record, the tap water measured 125 degrees F with a digital thermometer. Each pre warmed thermos was filled with water that was brought to a simmer and the thermoses were sealed. The temperature of the water was measured after 8 hours.
The Results
Thermos – 174 degrees
Zojirushi – 166 degrees
Bevu – 165 degrees
Yeti – 165 degrees
The Thermos Stainless King was the clear winner in the keeping hot drinks hot test. All the others held their own and kept their drinks very hot too. The design of the Thermos has a narrow neck that helps slow down heat transference as well as a secondary lid – the cup that helps retain heat.
Cold Coffee Thermos Test
I love a good iced coffee, especially in the summer. We tested the thermoses with water that was chilled in the refrigerator to a chilly 41.5 degrees F. The thermoses were pre chilled with cold tap water, but we also added 2 narrow ice cubes to each thermos – the kind made to be put in narrow openings of water bottles. We measured the temperatures after 8 hours.
The results
Thermos – 40.8 degrees
Zojirushi – 40.8 degrees
Bevu – 40.8 degrees
Yeti – 40.6 degrees
Each of our top picks performed exceptionally well with the Yeti doing just a little better than the others. One of the things I like about the Yeti is you can use full size ice cubes in it because of its wide opening. All the others would need the narrow ice cubes. I could even put a 2″ square ice cube in the Yeti.
Our Recommendations for Best Coffee Thermos
Thermos Stainless King 16 oz.
The classic thermos. I have so many different sizes of Thermos brand insulated bottles, and they always perform. The stopper doesn’t even need to be removed to pour, and the second lid makes for a convenient cup to drink out of. I’ve tossed these in my to go bag on a daily basis – they never leak and keep hot drinks hot for hours.
Yeti Rambler with Hot Shot Cap 18 oz.
This is my favorite of the bunch aesthetically. The hot shot cap is easy to drink out of and this also doesn’t leak, something we’ve been waiting for from Yeti for a while in a size that goes into a daily commuter bag. The convenience of being able to use full size ice cubes means your cold drinks stay icy all day without needing special ice molds.
Bevu DUO 10 Oz.
The Bevu bottle was by far the easiest to carry around. Your finger slips into the loop in the cap and makes for an easy to carry bottle. It also has a very pleasing texture, the Bevu is covered in a matte finish silicone that also provides a nice grip.
Zojirushi Stainless Steel Mug 16 Oz.
The Zojirushi was the only thermos we tested that had a locking mechanism. You can also drink right out of this by flipping the lid open. This particular model is stainless steel on the inside – other Zojirushi’s have a non-stick coating that didn’t appeal to us.
Ice Cube Sticks Mold
These are the ice cube molds that I use to make ice cubes to fit into the narrow necks of most insulated thermos bottles.
Cleaning your Coffee Thermos
Some of these say you can put their thermos right in the dishwasher, but I recommend hand washing. I use the OXO bottle brush to clean my thermoses and it works great. For stubborn stains I use Bottle Bright Tablets because sometimes staining will happen with coffee or tea. These tablets are all natural and work overnight to restore your thermos to like new condition.
We hope you find the vacuum insulated thermos that best suits your needs.
