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.

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.

Pros
  • Disassembles for cleaning
  • Possesses a pictograph lock
  • No spill over
  • Non-stick coating
Cons
  • Seals worse after some time of use

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.

Pros
  • Easy cleaning
  • Long temperature-keeping capacity
  • Large mouth for easy filling
  • Elegant and enduring
Cons

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.

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!

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.

Pros
  • Lightweight and compact
  • Very enduring
  • Long temperature retention
  • Lifetime guarantee
Cons
  • No catchy design – only conservative users will find it appealing

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.

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.

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.
