If you’re short on time, here’s the quick list. Keep reading for more details on each one and how to decide on the right coffee thermos for you!

Which coffee thermos is best for your lifestyle?

The thermos that works best for you will depend on what you want it to do. Do you need it to be leak-proof so you can toss it in your bag or are you looking for a thermos that is easy to drink your coffee from while you drive?

The answers to these questions will determine the best thermos that will fit for your needs.

Having a nice coffee thermos can save you money in a few ways. It may be an incentive to make your coffee at home to try out unique and fun coffee recipes.

Also, many coffee chains offer a discounted price on your coffee if you bring your own reusable cup. Using a stainless steel travel mug is better for the environment than single-use coffee cups, so it is a win for the environment and your wallet.

This article is looking at size, use, vacuum insulation, and cleaning to compare different thermoses on the market today so you can pick the best coffee thermos that fits with your lifestyle.

Coffee Thermos Size

coffee thermos

How much coffee or tea do you drink? Are you going to be sharing the contents of the thermos or is the thermos just for you? Are you looking for a travel mug that is easy to use?

Thermoses come in all shapes and sizes, so these questions will determine if you need a larger thermos or if a travel mug would be best.

Use

Thermoses come in all styles too. You want a thermos that best fits your lifestyle and capacity needs. Smaller, more lightweight tumbler-style thermoses are best for activities like commuting or a walk during lunch.

If camping or longer hikes are on your schedule, a bigger, more robust thermos with a screw-on lid would be the best coffee thermos to keep your beverage secured. 

Stainless Steel Thermos vs. Plastic Thermos

Insulation is the key factor when it comes to maintaining the temperature of your coffee. The best insulation is vacuum insulated with double stainless steel walls. Most vacuum insulated thermoses can keep coffee hot for 5 to 12 hours.

Plastic insulation is not as effective as vacuum insulation and will only retain the temperature of your coffee for a couple of hours.

Cleaning Your Thermos

4 different coffee thermoses

Many thermoses can be washed in the dishwasher, but the brand may recommend cleaning them by hand to make them last longer. You can check the manufacturer’s recommendations to see what they recommended best for the thermos you choose.

A mild detergent and a brush or sponge are all you need to clean a steel thermos. They can be soaked in water and dish soap if they have coffee stains or set-in odors. Vinegar and baking soda can be used if an odor or coffee stain is particularly stubborn.

There will be a reaction if these two chemicals are used together (think about that 5th-grade volcano experiment and then determine if this is a road you want to go down!)

I live in Minnesota where the winters are brutal. Our mail person has to walk their route (awful, I know!) and given the nature of my job as a blogger, I order a lot of items and therefore have a lot of deliveries each week. To keep my delivery friends happy, I leave out hot water with tea and hot cocoa packets for them to use.

I bought this carafe back in 2019 and use it all winter long. Outside. I fill it up in the morning with boiling water, set it outside in frigid weather (often times below 0) and when I dump it out at the end of the day it is STILL steaming.

It doesn’t leak, is easy to use and best of all keeps things hot!

Pros:

  • Keeps liquid hot for 12 hours
  • Easy to clean
  • Found on Amazon

FAQ

Will a thermos keep coffee hot overnight?

Some of them will and some of them will not. The best thermoses are usually vacuum insulated and made of stainless steel and can keep coffee warm for up to 24 hours. Most thermoses do not reach the 24 hour mark. A common range for most insulated thermoses is between 5 to 12 hours. The cold retention on thermoses will typically be longer than the heat retention. 

You can help your steel thermos retention out by priming it. Fill it with hot water for about 10 minutes to warm up the inside of your thermos before pouring your coffee in there. If this is not done, your drink can cool down a few degrees when you pour it into the thermos. Priming is not necessary for cold drinks, but if you are switching from a hot liquid to a cold liquid priming is a good idea or your beverage will warm up when you pour it into the thermos. You can prime your thermos for cold drinks using cold water or ice.

What is the best material for a thermos?

Stainless steel is considered the best material for thermoses. Stainless steel does not transfer as much heat as other metals making it a good insulator. It is also resistant to acidic drinks and has a neutral effect on odors and flavors.

Vacuum-sealed stainless steel thermoses have two layers of stainless steel. These are the best when it comes to insulation and heat retention for your coffee. Thermoses with a stainless steel inner layer and a plastic outer layer will not last as long and are prone to breaking.

How do you use a coffee thermos?

Priming your thermos is an important step that many people skip. Stainless steel is a cold material. If you want to keep your coffee hot for longer, it is best practice to warm up the cup before pouring your coffee in will help keep your coffee hot for hours. 

If you are a cold brew person, filling a thermos with ice and cold brew can make sure you have the best iced coffee all day long.
You can pour coffee or tea directly into thermoses, especially if you are using a travel mug. However, if you wanted to try one of the latest coffee recipes or tea each time you pour another mug, you can use it as a hot water thermos. This is good to do if you have several people using the same steel thermos for hot water to make different drinks.

How do you clean a coffee thermos?

Many thermoses are labeled as dishwasher safe, but hand washing may extend the life of the container. You can always check the brand’s recommendation for cleaning. This is important since some warranties might be voided if the thermoses are put in the dishwasher.

A mild detergent and a brush or sponge are all that are needed to clean a thermos and the lid. You can soak them if needed. For stubborn coffee stains, a mixture of baking soda and vinegar is best. These two chemicals cause a reaction, so be mindful of that. Stainless steel does not like bleach, so that should not be used for cleaning a thermos. 

Why does coffee taste different in a thermos?

Some serious coffee purists may say holding coffee in a thermos for a long time is an abomination because coffee oxidizes with time. Vacuum-sealed flasks can keep coffee hot for long enough that it basically slow cooks the coffee for too long. This affects the taste of the coffee and can make drinking coffee out of a thermos less appetizing for some people.
