Best Coffee Thermoses In 2020

Investing in coffee thermoses can be a step in making your mornings easier. It keeps your coffee warm while being portable so you can bring it anywhere. This article will go over what you should look for in a thermos and compare eight of our favorites. Keep reading to figure out which is the best coffee thermos for you!

Why should You get a thermos?

A quality thermos can be a worthwhile investment for anyone who is looking to cut down on coffee costs. Bringing your own coffee to work from home can save hundreds or even thousands of dollars a year, and give you that same caffeine boost to get through your day.

Thermoses can also help lower your food waste. The coffee you don’t finish while getting ready can be easily transferred to a thermos so you can continue to sip it on your commute. (Instead of having to throw hot coffee down the sink because you had no time to enjoy it). Bringing a reusable thermos to work is also environmentally friendly.

Not only does a steel thermos keep your coffee warmer or cooler than a single-use paper or plastic cup, reducing paper and plastic waste is an important step in lowering our carbon footprints.

What to look for in a thermos

It is important to buy a thermos that matches your coffee drinking habits. Here are some questions that you can ask yourself while perusing through the selection of thermoses available.

  • How much coffee do really I drink? If you need one pot minimum to keep your eyes open during that morning meeting, maybe opt for a larger, 61 oz. thermos. If you can get away with less coffee, then perhaps opt for a smaller, standard-sized thermos. A large one would take up unnecessary space and waste the contents that you do not drink.
  • How will I be transporting my thermos? Will your thermos be sitting nicely in the console of your car or will it be bouncing around your bag while your standing on the train? If your thermos is going to have a commute of its own in the morning, you may want to opt for one with a well-reviewed lid to ensure that the coffee makes it to your mouth, and not just all over the expensive electronics of your bag.
  • How long am I expecting my coffee to stay warm for? Higher-end thermoses tend to have better insulation than cheaper ones, so if you want your coffee to stay warm through the work day, it may be worth it to invest in a high-quality one. If you think you will drink your coffee within two hours, then you probably don’t need to pay for one with the best insulation.
  • How long do I want my thermos to last? Like any purchase, you get what you pay for. A high-quality, more expensive thermos may have a glass or stainless steel interior. While thermoses with plastic or tin inserts may be cheaper, they are ill-equipped for keeping beverages warm and degrade faster than glass or steel ones.

While the aforementioned utility features like size and insulation are the most important in terms of the quality of your thermos, chances are you’ll be carrying around your thermos every day, so you would want it to be fashionable! Here are some things to consider when choosing how you want your thermos to look.

  • Ease in which the lid opens/closes.
  • Color/design
  • Dishwasher-safe or hand wash only
  • Strap/handle
  • Brand

Thermos tips!

Here are some tips that will keep your coffee warm and your mornings running smoothly.

  • Prime your mug by pouring boiling water in your mug 5-15 minutes before putting your coffee in to keep your coffee hotter for longer. Here is a video explaining how and why you should prime a thermos.
  • Even if a travel mug claims to be dishwasher safe, washing it by hand with a bottle brush can help lengthen its life by protecting it from harsh dishwasher detergents. Daily use can make your tumbler susceptible to coffee stains. Here is a helpful video that shows how to remove lingering smells from steel thermoses.

Hopefully, answering those questions has narrowed down what type of coffee thermos you want. Here are some of our favorites so you can begin comparing and shopping!
