Best Thermoses for Keeping Coffee & Tea Hot | And Cold Drinks Cold!

Drinking coffee is one of life's great culinary pleasures. I prefer mine with a little bit of frothed fresh soymilk, but that's besides the point. Unless you're specifically having cold brew or iced coffee, the heavenly juice of the coffee bean is best enjoyed hot. Pouring your coffee into just a regular old mug might be good for a few minutes, but after the first few sips the temperature has drastically dropped along with the vibrant flavor notes. That's why anyone making coffee to-go (or even at home) should invest in a good thermos.

Why Not Just Use Any Coffee Thermos?​

There's a huge difference between a high quality hot liquid thermos and a low quality one. A high quality one will keep your coffee hot for hours upon hours. You could literally pour your brew at 9AM and still be sipping at 12PM, while still enjoying it at peak flavor and temperature. It's quite an amazing experience.

With an ordinary cup or mug your coffee is going to be getting cold in as little as 5-10 minutes. You're then stuck with a sludgy and lukewarm liquid void of all of the original flavor and aroma.

There'a also the bonus of going into your favorite coffee shop and asking them to fill up your mug instead of a paper or plastic cup. Not only is this obviously ideal for environmental reasons, but some places will actually charge you less for the coffee or tea if you don't take one of their mugs.​

Can You Use These for Other Things?

Even though we've picked thermoses that are the ideal size for coffee, tea, or other hot drinks, it is also possible to use them for hot soup. There are indeed other types of thermoses that work better for soup due to their size and accessory parts. However, if you carry an extra soup bowl or mug with you you can simply just prepare your soup in the morning and enjoy it hot in the afternoon.

We've compiled an entire separate post on the best thermoses for keeping food warm or cold if you need something a bit more versatile.

What Makes These Products Different from Each Other?

What separates these products out from the rest of the market is their insulation power. If you go to your local dollar-store and pick up any thermos, it's not likely to be well insulated.

The sealing mechanisms for some of the thermoses below are also rather high-tech, specifically on the first Contigo. Even if they aren't high-tech, most of the mugs we've selected have decent sealing mechanisms which is another critical component to keeping liquid hot.​

Our Picks for Best Thermoses for Keeping Coffee Hot

Contigo Autoseal Insulated Stainless Steel Vacuum Mug

Contigo AUTOSEAL West Loop Stainless Steel Travel Mug , 20 oz., Stainless Steel

The Contigo is the a sleek and simple example of an insulated vacuum thermos. It's tall and thin which makes it easy to fit into cup holders. By having a vacuum seal lid this thermos allows you to keep hot drinks hot up to 7 hours and cold drinks cold up to 18. Unlike other thermoses which can require two hands to properly open the lid to take a sip, the Contigo's ergonomic button allows you to do it with just one, making it ideal for multitasking.

What We Love About This Thermos!

  • Autoseal lid mechanism makes opening and closing the thermos super easy - and also keeps it super tight!
  • Extremely long insulation times.
  • Easy to fit into cup holders with tall and thin design.

Contigo Stainless Steel Vacuum Snapseal 

Contigo SnapSeal Byron Vacuum-Insulated Stainless Steel Travel Mug, 16 oz, Gunmetal

This other Contigo thermos is the more basic version of the Autoseal unit. Instead of coming with a spring loaded vacuum sealed button, it comes with a tight snap seal which the user just flicks up or down to take a sip or to close it up. It has a bit less insulated power than the Autoseal, but will still keep your hot beverages like coffee hot for up to 6 hours. Consider the SnapSeal model if you want something that's a bit more simple.

What We Love About This Thermos!

  • A simple yet very effective budget minded model for keeping liquids warm or cool.
  • Ergonomic grip sleeve makes it easy to hold onto and reduces likely-hood that you'll drop it!
  • Well insulated and lengthy keep warm and cool times.

YETI Rambler Vacuum Tumbler

YETI Rambler 20 oz Stainless Steel Vacuum Insulated Tumbler with Lid (Stainless Steel)

The Yeti is one of the most popular insulated thermoses on the market. There's not much to say about it other than its a really solid insulated tumbler cup. Because its so popular, there's also tons of accessories for it and many different models. Some of the accessories include different lids (such as a magnet sealing lid) and a handle for easy sipping. You can't go wrong with a Yeti!

What We Love About This Thermos!

  • Reliable and solid insulation technology!
  • Has tons of different accessory options available on the market including a handle and different lid.
  • Extremely popular and well recognized brand name.

AVITO Stainless Steel Coffee Mugs with Lids

Stainless Steel Coffee Mugs with Lids - 14 Oz Double Walled Insulated Coffee Beer Mugs - Set of 2 by Avito - Best Value - BPA Free Healthy Choice - Shatterproof and Spill Resistant

We wanted to include two simple mugs on this list because there is something a bit different about drinking your coffee from a mug compared to a tumbler or thermos. It offers more of a "home-ey" slow sipping experience rather than the feeling of being always on the go. Unfortunately, classic ceramic coffee mugs offer a great sipping experience, but are lacking in the heat retention department. These stainless steel mugs offer the best of both worlds.

What We Love About These Mugs!

  • Offers insulation and the original coffee drinking experience due to the shape of the mug.
  • Handle makes the experience easy and ergonomic, doesn't require a lot of gripping power.
  • Beats a ceramic mug in insulation power any day of the week!

Simply Modern Cruiser Tumbler Flask

Simple Modern 20oz Cruiser Tumbler - Vacuum Insulated Double Wall Coffee & Tea Cup - 20 ounce 18/8 Stainless Steel Silver Travel Mug - Simple Stainless

The Simply Modern Cruiser Tumbler is quite similar to the Yeti, but it is manufactured with a wide range of color options. This is great for the user who is aesthetically minded, but still wants to keep their coffee warm! They're also manufactured in a wide variety of sizes all the way up to 36 oz!

What We Love About These Mugs!

  • Offers insulation and the original coffee drinking experience due to the shape of the mug.
  • Handle makes the experience easy and ergonomic, doesn't require a lot of gripping power.
  • Beats a ceramic mug in insulation power any day of the week!
