Starbucks and Aladdin Out of the List… You Wonder Why?

You might be wondering why I have neglected the Starbucks Stainless Steel Tumbler, a highly popular and stylish thermos model, in this review?

That’s very simple:

  • This one cannot be in any way called a top coffee thermos because it leaks badly;
  • Yes, it has a convenient band of rubber around it, but this rubber is very non-durable and spoils too quickly to rate this thermos highly;
  • To make things even worse, I would note that the rubber strap can hardly be restored by cleaning or washing, so if you are planning to use your best thermos for coffee for years, that’s definitely not an option.

Another debatable model is the Aladdin Heritage Plaid Vacuum Bottle.

There has been much fuss about its quality, design, and overall service… However, I cannot share all that thrill, since for me:

  • It looks too retro;
  • It has too few attractive options and add-ons with which numerous thermos models are now abundant for it to be included in the best coffee thermos list;
  • Fans of old school, forgive me, but except for the 12-hour capacity of keeping the temperature of liquids, this thermos can hardly boast any engaging extras.
To crown it all, the thermos lacks corrosion resistance and can be easily scratched, which is surely a failing choice for active users needing a thermos for outdoor activities, travel, and sports – a questionable choice under the condition of abundance of much more durable and stylish items in the market.

Now let’s look at the 16 best-rated coffee thermos items to see why they have won the race and what advantages you may derive from buying them.

1. Contigo AUTOSEAL West Loop Vacuum Insulated Stainless Steel Travel Mug

Meet the winner, it is the Contigo Autoseal West Loop Insulated travel mug made of stainless steel!

I personally use it now and absolutely satisfied with it. Everything is cool about it – a great number of stylish colors, minimalist design of the thermos, and the autoseal function helps you not to leak the liquid between sips.

This pleasant extra makes the thermos highly convenient to use on the go or during driving, which gives it an extra score in my rating. Moreover, I find the double-wall vacuum-insulated stainless steel flask of this thermos safe and secure.

  • Easy cleaning due to opening lid pivots
  • Can be washed in the dishwasher
  • Keeps coffee hot all day long!
  • No sweat, no spill over
  • On the go safety
  • Autoseal protecting from accidental leakage
  • 100% BPA free
  • Without brush aluminum finish
  • If cleaned in a dishwasher often, paint may peel off quickly
  • Hard to fit under a Keurig

All these features together with the lifetime guarantee (though limited) contribute to my sureness in this product’s durability – in other words, this is my choice of the best coffee thermos for 2020.

$47.86  in stock
5 new from $46.86
as of January 27, 2023 7:14 pm

This thermos may also be regarded as the best small coffee thermos due to its extensive heat- and cold-preserving capacity achieved due to innovative technology of double-wall vacuum insulation.
What I like about it most is the “dry hands” effect preventing sweating no matter whether hot or cold liquids are in the thermos.
Added to its profound puncture and rust resistance, these extras make it a durable and reliable partner on all occasions, whether it is a drive to work or a picnic in the mountains.

  • No sweat with cold and hot drinks
  • Dishwasher-safe lids
  • Extensive shutter resistance
  • Sometimes the tip-over spills occur
  • Does not fit many car cup holders
  • Lids sometimes do not seal completely
  • Expensive

Overall, this thermos will guarantee long hours of keeping your coffee hot, easy to clean and pleasant to use – a good choice to make when selecting the best insulated coffee thermos.

 out of stock
as of January 27, 2023 7:14 pm

Many reviewers rated this thermos as the best thermos for coffee ever, and I agree that this thermos is definitely a great choice to make!

What I like most about this model is a variety of fresh, original colors (you can choose among the Coral Pink, Turquoise Blue, Pearl Pink, and other color options) and an ability to disassemble it for cleaning.

It is also impossible to leave stains on its even surface, while the tiny dimensions allow fitting it into the smallest spaces in your bag, rucksack, or the car’s cup holder.

  • Disassembles for cleaning
  • Possesses a pictograph lock
  • No spill over
  • Non-stick coating
  • Seals worse after some time of use
  • Inconvenient to drink from the broad mouth of thermos
  • Over-engineered (too many gaskets and parts)

Easy to clean, lightweight thermos with no-stain effect – what else can one desire from the best hot coffee thermos?

4. Thermos 51 Ounce Vacuum Insulated Stainless Steel Carafe

 out of stock
as of January 27, 2023 7:14 pm

The most important thing to say about this item is that it’s the best LARGE coffee thermos!

Despite its large size and considerable weight, it also promises to keep your coffee hot for 12 hours, while cold liquids stay cold for over 24 hours, amazing!

Its innovative vacuum insulation technology enables such great capacity and is also quite convenient despite its size. I also find it super-easy to clean, and its rubber seals are very durable – an important plus for a thermos like this.

  • Easy cleaning
  • Long temperature-keeping capacity
  • Large mouth for easy filling
  • Elegant and enduring
  • Inconvenient to get the last few drops
  • High price

This thermos is a perfect selection for a large family, since it has outstanding temperature-keeping capacity and a huge volume to enjoy your drinks all day long.

5. RTIC 30 oz. Tumbler

$24.75  in stock
3 new from $19.79

as of January 27, 2023 7:14 pm

What I like most about this thermos is its impressive 24+hours of temperature retention. The majority of thermoses I tested coped with the maximum challenge of preserving heat within 3-4 hours, while this one’s performance is outstanding.

Another benefit for me personally is its perfect fit for a cup holder in the car – too many thermoses were unjustly removed because of my inability to use them when driving.

  • Prolonged temperature retention
  • No sweat on the thermos’s exterior
  • Lower price compared to counterparts with similar features (e.g., Yeti)
  • No dishwasher cleaning, only hand washing
  • No seal, high risk of spills

A reliable and convenient counterpart to some similar but higher-priced thermoses – what can I say? It’s probably the best thermos to keep coffee hot all day long!

6. Thermos Vacuum Insulated 25 Ounce Compact Bottle Beverage Bottle

 out of stock
as of January 27, 2023 7:14 pm

This thermos looks plain at the first sight, and you might wonder why is it the best flask for coffee?

Wait a minute – elegance and minimalism are fashionable nowadays, and having a lightweight, simple, but at the same time perfectly heat- and cold-preserving thermos is great luck!

I like everything in this simple and reliable device – its long hours of temperature retention, the built-in cup allowing me to enjoy a cup of hot coffee anywhere, and obviously, its compact suitability to bags, car cup holders, and even carrying it in a hand.

  • Lightweight and compact
  • Very enduring
  • Long temperature retention
  • Lifetime guarantee
  • No catchy design – only conservative users will find it appealing
  • Hand-washing recommended for prolonged use

Given the benefits discussed above, I find it one of the best coffee thermoses of stainless steel, and I am sure all happy owners of this item will agree with me.

as of January 27, 2023 7:14 pm

I included this thermos into the top 14 rating because of its superb design. It truly differs from all other thermoses I have ever seen, so I rate it as the best thermos for coffee in terms of style and visual appeal.

Designers and promoters of Contigo did their best with this product line, it is essential to take a look at the color options: Stormy Weather, Matte Black, Monaco-Tumbler, Grayed Jade, etc.

I would buy one just for these rich, juicy colors – but luckily, that’s not all Contigo offers in this model. Other pleasant benefits of buying this thermos include considerable volume of liquid (approximately 20 ounces), a leak-proof lid, easy one-hand use, and easy cleaning.

  • Leak-proof lid
  • High volume of liquid
  • Lifetime guarantee
  • Beautiful color options
  • Only hand washing
  • Not to be used in microwaves and refrigerators
  • Sometimes a problem may occur with proper screwing of the lid

What else can I say? It’s a beautiful selection for modern, stylish people with a passion to nice-looking accessories.

FAQs or Did You Know…

Read these FAQs and to understand what you have to keep in mind when considering a certain item.

How to make sure that my thermos is safe?

The quality of content and composition of any thermos matters much during thermos selection, since you pour hot liquid in it. In case the internal cover is made of low-quality, toxic materials, you may be poisoned or seriously intoxicated with hot liquids staying in such a thermos.

Hence, look for thermoses produced in compliance with the Consumer Product Safety Commission’s (CPSC) and the Consumer Product Safety Improvement Act’s (CPSIA) requirements to be fully confident in the quality of your thermos.

Other information you should check is:

  • Whether the thermos contains phthalates
  • Whether it is made without BPA
  • Whether it contains lead.
Is it better to select a stainless steel or plastic thermos?

As you might have seen in this review, all top-rated coffee thermoses discussed here are made of stainless steel, which ensures longer heat- and cold-saving capacity and helps these items keep their promise.

However, their major minus is weight; you can hardly spend the entire day walking with such a thermos in your hands or bag; especially when full, they may be too heavy for walking on foot.
In all other terms, it is entirely up to you to decide depending on your use intentions – there are no feasible differences in quality and length of service.

Is the steel taste of coffee from my thermos normal?

If you are allergic to steel, then you may feel the discomforting taste of steel in your liquids stored in the stainless-steel thermoses. In this case, I would recommend buying a plastic thermos; it has lower heat-storing capacity, but you will not have the discomfort.
If you are not allergic, the problem may be with the integrity of the stainless-steel thermos flask, and you should apply for the exchange of your defected thermos for a new one.

What is the best way to clean thermoses?

It also depends on the producer’s instructions. Some thermoses can endure the dishwashing machine, while others accept only hand-washing.
I strongly recommend hand-washing, since it is not as traumatic as the lengthy dishwasher regime is to your thermos, and will help it serve you longer.

What warranty length is fine for thermoses?

Different producers provide different warranty lengths; the most common is a 5-year warranty for the heat- and cold-saving capacity of the thermos. However, some reliable brands go as far as to provide the lifelong warranty for their products (e.g., Stanley PMI, Contigo, etc.).

What is the best way to clean a coffee thermos?

It is important to clean all the parts with warm soapy water after using your flask. Ensure that you rinse it carefully with hot water. It is recommended that you hand wash your thermos instead of using a dishwasher. There are many methods of removing stubborn stains such as using bicarbonate of soda and vinegar. Dry your thermos by letting it drain excess water.

      Hi! Yes, they are, as I selected only BPA-free thermoses for review. Nickel is quite dangerous for our health, you know!
