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 get 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 10 best-rated coffee thermos items to see why they have won the race and what advantages you may derive from buying them.

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.

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, reliable partner on all occasions, whether it is a drive to work or a picnic in the mountains.

Pros
  • No sweat with cold and hot drinks
  • Dishwasher-safe lids
  • Extensive shutter resistance

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 cupholder.

  • Disassembles for cleaning
  • Possesses a pictograph lock
  • No spill over
  • Non-stick coating
Cons

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 enable such great capacity, while one-handed use 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 the thermos like this.

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

What I like most about this thermos is its 24+ hours of temperature retention, which is truly impressive! 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 to a cupholder in the car – too many thermoses were unjustly removed because of my inability to use them when driving.

Pros
  • Prolonged temperature retention
  • No sweat on the thermos’s exterior
  • Lower price compared to counterparts with similar features (e.g., Yeti)
Cons
  • 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!

I find everything about this HappyGo thermos perfect – it’s fairly priced, has a sipping cap that also functions as its cap, and has the vertical lock lid for convenient use thereof during travel.

Its 12+ hours of temperature preservation are also quite impressive, though previously reviewed thermoses can definitely boast more hours of keeping your coffee hot or ice-cold.

Thus, I find this thermos to be the best coffee thermos for work – durable enough for you to enjoy your hot morning drink while you’re getting to the workplace.

Pros
  • Simple cleaning
  • Light weight and portability
  • Wide mouth
  • No-sweat effect during ice storage
  • Disassembles for thorough cleaning
  • No leaks with a sealing lid
Cons
  • Shorter temperature retention as compared to Yeti or Thermos brands
  • The cap and plug look simplistic and cheap

Overall, it is a very nice thermos to keep coffee hot, and I can readily call it the best thermos bottle for hot coffee because it does not lick. It fits my cupholder perfectly, and it keeps all its promises – a secure and durable thermos to acquire.

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 cupholders, and even carrying it in a hand.

Pros

Thermos has always been the global leader of thermos production, and I find this model amazing with its stylish appearance and simple elegance, truly the best thermos flask for coffee one may dream of.

Besides highly attractive looks, it also impresses with extraordinary durability: over 24 hours of cold retention! The promised 12 hours of keeping coffee hot are also working time – these characteristics make this thermos an ideal choice for a variety of purposes.

Pros
  • Available in different sizes
  • The use of patented vacuum insulation ensures long temperature retention
  • The lid is a cup for convenient drinking

I included this thermos into the top 10 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 enough 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.

Pros
  • Leak-proof lid
  • High volume of liquid
  • Lifetime guarantee
  • Beautiful color options
Cons
  • 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.

The final thermos that got into my top 10 is the thermos bottle from North22. Though it cannot be called a thermos in the full sense of this word and the producer prefers to call it a vacuum insulated bottle, it is indeed a good-working thermos.
I found the wide mouth and two lids the most enjoyable part of it, since this design makes it much easier to drink from this item. This feature makes it universal for the use on the move and in everyday use.

Pros
  • No condensation on the surface of thermos
  • Two different kinds of caps for flexible use
  • Long temperature preservation
Cons
  • Non-durable and highly vulnerable to dropping
  • Heavier than plastic insulated bottles

My conclusion is: this thermos is highly user-friendly because of its adaptivity. Exchange the usual cap for the cap with a top straw lid and enjoy your drink when driving or walking – with this thermos, flexible use becomes real.

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.).
