The best way to enjoy your coffee is while it is still hot and fresh because this will keep you alert and energized throughout the day. Before you can achieve this, you will either have to make a fresh pot of coffee each time or store certain quantities in a thermos flask. In both cases, you will always need to make new coffee every day due to the fact that coffee can get stalled easily, but the latter will ensure this does not happen within a few hours.
A Thermos for storing coffee, milk, beverages, and other liquids in its vacuum can ensure that your drink stays hot or cold for a long period. As a result, you can enjoy your perfect brew at work, school, or while on the go. It is an inexpensive method of keeping your coffee hot for indoors and outdoors activities, while at the same time providing ease of usage.
For the best result, you need a Thermos that can retain heat for at least 8 hours, does not spill or leak, and has a size that is suitable for the environment you are going to use it. Due to the variety of these products, it becomes difficult to find one that meets these criteria. On the other hand, our thermos for coffee buying guide will make it easier for you, while ensuring that the thermos you get is of high quality.
Before we proceed, let’s understand what a thermos is.
What is A Thermos?
First designed by Sir James Dewar in 1892, a Thermos also known as a vacuum flask or Dewar bottle is an insulating container that preserves the coldness or hotness of contents stored in it for a long period. Mostly used to store coffee, tea, cold or hot water, It can maintain its temperature for a few hours before it finally drops or rises.
This is made possible by the nature of their construction where one of two flasks is placed within the other. They are both joined at the brim and separated by a vacuum (Insulator). Between both materials, there is no air to transfer heat and as such, a Thermos can minimize heat transfer due to conduction and convection.
Additionally, to minimize heat loss through radiation, a Thermos is usually coated with silver. If this is not done, the inner flasks will be able to radiate heat towards the contents of the bottle and as a consequence, heat will be able to escape. Conclusively, the vacuum minimizes heat transfer, the tight stopper prevents air from entering or leaving the flask, and the silver lining prevents convection.

Why Should I Get A Thermos?
There are several reasons why you should get a Thermos because this Vacuum flask is extremely beneficial to both children and adults. Due to the fact that they come in different shapes and sizes, they are not limited to use within a certain place or location. It could be in the school, at home or work, camp, or while traveling, here are some reasons why you should get a Thermos:
1. To preserve heat and cold
The main purpose of a Thermos is to minimize heat transfer or loss. That being the case, a Thermos will save you the time required to brew another cup coffee in a cold weather because it can still maintain the original taste of the coffee stored in it. Also, food stored in a good Thermos does not easily get cold therefore, you can keep your food hot and fresh in a Thermos till whenever you need it.
2. To cut cost and save money
If you are a lover of caffeine and can’t go a day without a few cups of coffee, then you need a Thermos. This is because it can preserve heat and it is very portable hence, you can make your coffee and store it there. What this does is save that extra cash you would’ve spent to buy several cups of coffee. You may feel it’s just a few dollars, but add it to your year’s expenditure on only coffee and that might be hundreds of dollars.
3. To prevent dehydration
It is a known fact that we tend to drink more when we have a bottle of water around us. While this may be our brain playing a trick on us, it can help prevent dehydration since you will not have to wait till when you’re thirsty before having a drink. You can go cycling, camping, and running with a Thermos which will prevent dehydration that can lead to muscle cramps, fatigue, dizziness, and headaches.
Features To Consider Before Buying
Before you dish out money to buy a Thermos for coffee you may be unimpressed with, there are certain features you have to put into consideration before settling for one.
This because while they may all have the same principle of operation, each is made of a different material which determines its quality. As a result, how long it’ll minimize heat loss and serve you will be determined by these features.
The first thing you’ll have to consider is the size of the Thermos you plan on buying. This must be in relation to where you intend using it.
For instance, do you need a Thermos for home or workplace? School, traveling, or camping? and so on. In the home or office, you’ll definitely need a large Thermos that you can serve several cups of coffee or tea from.
On the other hand, if you plan on going hiking or camping, you’ll need a Thermos that is small and portable in size. This will allow for ease of usage and movement while at the same time keeps you hydrated and refreshed.
Most importantly, the size will determine its price thus, there’s no use paying less for a small Thermos you’ll be using only at home or paying more for a larger Thermos you’ll have difficulty carrying about.
Some Thermoses come with a glass vacuum while others come with a metal or steel vacuum and the major difference between both is their durability. A metal vacuum will be able to withstand the impact of hits and falls for a long time without cracking while a glass vacuum will easily crack on contact with hard or sharp objects.
There is also plastic Thermos, but this type can only serve as a food or liquid container since it can’t preserve heat for hours.
Alternatively, a glass or plastic vacuum may be cheaper than a metallic build, but the latter is better. It can retain heat for a longer period but may be quite pricey.
For this reason, you need to determine how much you’re willing to spend for a Thermos because this will help you decide if you should settle for a less expensive material that is not durable or a more expensive and long-lasting material.
3. Heat retention
Sometimes specified by manufacturers, is how long their Thermos will be able to retain heat which is usually from 3 to 24 hours. Although in real-life operation, this retention time might be lesser, it can still give you an idea of how long your coffee or tea will remain hot before it becomes warm.
Additionally, if you do not trust the manufacturer’s claims, you can rely on the reviews and recommendations of customers who have already purchased the Thermos.
Now, depending on the purpose of your purchase, you can determine if the Thermos will serve you well. That is to say, if you want a Thermos that is in the form of a mug which is suitable for going for a walk with, then 3 to 5 hours may be a good buy.
On the other hand, this heat retention time is not suitable for a large Thermos meant for the home or office, since it needs to retain heat for long hours.
4. The Lid
One more feature you have to consider is the lid of the Thermos. Here, the lid or cup must be made of the same material as the body of the Thermos.
This will allow it to prevent heat loss through convection where the passage of air into and from the Thermos is not allowed. As a consequence, the liquid will tend to lose its heat slowly.
Moreover, a Thermos that has this type of lid will be fastened securely thereby avoiding spills when shaken or when it falls. Even with a tight-fitting, it must also be easy to loosen and fit back easily without leaking as is the case of thermoses that use corks as an opening.
With these in mind, the better option for a lid is one that has similar material to the body and is in the form of a screw cap.
The flask warranty is also of importance especially if you’re going to spend a couple of dollars on a large Thermos that is made of steel. Some Thermos come with one year to five years warranty, and depending on which is a better bargainer for you, you can decide whether you should settle for the flask or not.
Keep in mind that if it has a long warranty, you can assume that it is a product that has been built to last to a certain degree.
Additionally, you can always be on the safe side by being able to return the product if it leaks or does not retain heat to the hours specified by the manufacturer.
What’s more, there are some that do not offer any warranty and as such, you are not covered if problems occur while you’re just trying out the product for the first few days or weeks. On this note, it’d be best to settle for one with a warranty.
How to Choose the Best Thermos
A wide collection of Thermoses means you have a variety of shapes, sizes, and designs to choose from. Although this is a good thing, it also comes with a downside and that is, the difficulty in choosing the best Thermos from this collection.
You may pick one that offers less value than what you paid or be lucky enough to find the right product that does not leak or spill. Now, to ensure that your chosen Thermos is the best buy, keep the following tips in mind.
A Thermos may have a plastic, glass, or steel vacuum. Each of these has an advantage over the other and also a disadvantage.
Of all three, the cheapest is a Thermos with a plastic vacuum because its build material cannot retain heat for a long time. Likewise, a glass vacuum is cheaper, easier to clean, and can retain heat longer than plastic but it is the most fragile.
In the same vein, a steel vacuum on a Thermos is the most expensive of the trio, most durable, and has the highest heat-retaining power.
As a result, if you want the best and you’re willing to spend the extra cash for a Thermos that will last for a long time and also keep your coffee hot, then you should settle for a Thermos made of steel.
The size will determine the amount of liquid the Thermos can contain. In that regards, you should choose a Thermos based on where you intend using it or taking it to.
If you plan on going for a walk, run, climb, and other outdoor activities, then you need a moderately sized Thermos whose size is comparable to that of a water bottle. A Thermos mug may also be suitable for going on a short walk.
On the other hand, you need a large Thermos at home, office, or for business purposes. This is because they can contain more liquid and can serve a larger number of people from one full fill.
Asides having more than enough content to last you for hours or through the say, it can slow down heat loss thereby maintaining the taste of your coffee.
Buying a Thermos that is more expensive than another may at first translate to it having more value, but this is not entirely true. Nowadays, the price of a product does not always equate its worth and as such, you may pay more for a defective product and pay less for a product that may be more useful to you than the later.
Whichever is the case, the price should not be a major determinant in deciding the best product to buy. The best may either be a cheap product or an expensive one and your ability to ascertain which is better is based on the unbiased reviews and recommendations of customers.
On the other hand, a product will always have negative reviews since human wants are insatiable hence, you need to weigh the good and bad reviews then make a decision.
4. Listen for hollow sounds
To check the quality of the Thermos you have chosen, and ascertain if it has leaks or breakage, you can listen for hollow sounds.
This can be done by placing the opening of the flask near your ear and if a sound is heard, then it does not have leakages in it. On the other hand, if there is no subtle sound, it is most likely a defective product.
Now it may not be a thing of worry if there this defective Thermos has a product warranty since you can always get a replacement.
On the other hand, it’ll be a total loss to you if there was no guarantee of replacement if defective. For this reason, always settle for a Thermos that has a Warranty which will ensure you get a replacement if damage occurs within the stipulated time.
How do i make sure that my thermos is safe?
To ensure your thermos is safe for use, ensure that you clean it properly before and after use. In the case of a stainless steel thermos, you may need a baking soda or vinegar to maintain it and avoid corrosion.
Moreover, you should ensure that is left to dry in a clean place to prevent odor and rusting.
Is it better to select a stainless steel or plastic thermos?
A stainless steel Thermos is more expensive than a plastic thermos, but it can retain heat for several hours. On the other hand, a plastic Thermos cannot retain heat for a long time due to the nature of its material.
For these reasons, it is better to select a stainless steel thermos over a plastic Thermos for your coffee because it minimizes heat transfer.
Is the steel taste of coffee from my thermos normal?
No, it isn’t. This is because Steel is not porous and as a result, it cannot add flavor to your coffee. That being the case, the taste may be as a result of the poor construction of the Thermos or a thermodynamic reaction between the coffee compounds and the metal.
You can easily eliminate this taste by cleaning your Thermos vacuum with a solution of vinegar and water.
What is the best way to clean thermoses?
Thermoses should be cleaned on a regular basis to prevent odor from forming from leftover content. A Steel Thermos can be cleaned by adding vinegar to the flask and shaking vigorously. It can then be rinsed with lukewarm water.
Also, you can clean a glass Thermos by adding warm water and soap, then shaking vigorously. Finally, rinse your Thermos with water after a final wash.
What warranty length is fine for thermoses?
Some Thermoses come with a limited time warranty to cover certain cases in defective products while others have a lifetime warranty.
In either case, a 5 to 10-year warranty is good enough for Thermoses as this is a long time which will ensure that you get good value for your money while the product is free from defects in materials or workmanship.
