Why Should You Get A Coffee Thermos?
A well-built thermos can give you a head-start every day. You can quickly make coffee when in a hurry and sip it on the go. You won’t have to scald your mouth on a boiling hot cup of coffee or throw a half-full cup into the bin because you don’t have the time to enjoy it and it will become cold. A thermos also works well for those who enjoy camping.
When choosing a thermos, consider your coffee-drinking habits and then make a choice. A thermos which isn’t constructed using good-quality materials starts leaking after a few days or will fail to keep your coffee warm. It is not only suitable for travelers or campers, but you can also take it with you to school, office, picnics, evening walks, casual dates, etc.
Its compact build allows you to enjoy your coffee anytime, anywhere. The features to consider are also determined by where and how you are going to use it. There are a plethora of designs available on the market today; you just need to think carefully and make the right choice. To help you with that, we have compiled a list of a few essential factors to consider before purchasing the best thermos for coffee.
Important Factors To Consider Before Buying The Best Thermos For Coffee
Thermal flasks can be extremely handy as well as cost-effective if you take your hot drink or coffee to work in them, instead of spending money on costly coffee shops like Starbucks. You can use a thermos to take anything with you, ranging from soup to green tea. It is very useful for regular coffee drinkers who like to enjoy their cup without any rush.
You can get a taste of your coffee wherever you go. But there are a few things you need to check before you purchase a thermos. You need to be sure of what you are going to use it for. For example; are you buying it to regularly carry with you on your way to the office or for hiking tours? Do you want to use it for cold coffee or other cold drinks or only hot beverages? Here is a detailed list of a few factors you need to keep in mind to make the best out of your purchase.
1. The Size Of The Thermos
Are you going to be the sole user of the thermos, or do you plan on sharing it with your camping partners or a date? You even need to consider the quantity of coffee you usually brew and drink. If you are looking to buy a shareable thermos, or you like drinking a lot of coffee, you should choose a thermos which offers great capacity.
You also need to know that a large thermos means it will be heavier and take up a lot of space in your bag. But at least you will have enough coffee to help you get going. If you like keeping it compact and light, it is better to opt for a smaller thermos. If you travel often, we recommend you to go for a thermos that can fit in any vehicle’s cup holders. The size of the thermos also determines its price, so think before you make a decision.
2. Insulation Properties Are Important
Insulation determines for what length of time the thermos can maintain the temperature of a beverage (hot or cold). The way a thermos is constructed determines the insulation’s effectiveness. Some of the high-quality models are made with double-wall stainless steel, and are vacuum insulated. However, there are some low-quality models available which are made using tin or plastic. These are no match to the stainless steel ones when it comes to insulation.
Plastic or tin thermoses work well for commuting or other short-term use, but they start leaking after some time and also struggle to retain a beverage’s temperature. It is known that plastic is not a good conductor of heat. Thus it is better to invest in a stainless-steel best coffee thermos.
This is the main difference between a plastic thermos and a high-end one. Everybody likes their coffee hot, so if you are not struggling with your budget, it is advised you invest in a good-quality coffee thermos. If you want to keep your beverage hot for more than a few hours, as some people need a thermos for overnight use, you will need to spend more money.
3. Design And Other Features
While size and insulation are some of the major considerations, there are other features you need to consider as well. The way a thermos is designed can affect its ease of use. Everyone appreciates different things, so there is no right or wrong here. You just need to find what you value the most in product design.
You may also want to check if a thermos has handles to make it easier for you to carry it around (it is a great feature if the flask tends to get hot). Some models come with a free carry bag to keep the thermos wrapped up and prevent any sort of leakage.
You might also want to choose a thermos which comes with a warranty or a cash back guarantee. It is important to consider, especially if you are buying online. The warranty and easy return policies are for your assistance if you are not able to test it beforehand. You can send the product back and demand a refund if it doesn’t work properly
4. Evaluate The Delivery System
You must consider how you are supposed to sip your coffee from the thermos. Does it come with a metal straw, a sipping hole, or an adjustable mouthpiece? Does the lid come off, allowing you to use it as a small cup to pour coffee into.
You also need to consider the grip it provides. You should be able to handle using one hand while driving or going down a busy lane carrying your other belongings
When buying products for regular use, considering these small factors is necessary, no matter how futile they may seem. The one which is easy to handle is definitely the best thermos for keeping coffee hot.
5. Envision Using It Regularly
If you are a coffee addict, you will probably use a thermos almost every day, so make sure you are not bothered by its quirks. For example, can it be put into the dishwasher or does it need to be washed by hand? Does it come with small, finicky components that are tough to clean? Do odors and stains stick to its interiors?
If you are buying a thermos just to drink coffee, then the left-over coffee smell may not irritate you as you will use it solely for coffee. But if you are purchasing a thermos to pour in different kinds of beverages every day, you need to make sure that its cleaning process is easy.
6. Beware Of Spills
The best coffee thermos can be tilted, shaken, dropped, flung from a balcony, or steeped on without even a single drop of liquid spilling from its seal or lid. Unfortunately, many models do not meet this standard. You have to make sure to analyze the product’s technology and read online reviews or else opt for a reputed high-end.
There are a variety of thermos flasks available online, and you can choose from the cheapest to the most costly one. It is easy to assume that the higher the price the greater the quality and build of the product. But this is not always the case. You can find sundry cheap thermoses which function really well and offer features just like any highly expensive thermos.
It is recommended that you check customer reviews to figure out if the promises made by the manufacturer are legitimate. The next section of our guide lists some of the most popular coffee thermoses available online. We have tried covering products of different price ranges to make sure you are able to find a thermos which fits your budget.
8. Lid Of The Thermos
The lid or seal of the thermos is another important factor to consider. As already mentioned, the quality of the lid determines if the thermos will leak or not. People assume that a costly thermos manufactured by a popular company will not leak. Sadly, this is not the case. You need to go through customer reviews to find out if its lid functions properly.
You will also see several coffee thermoses which come with a cap which can be turned into a small cup. If you like to sip your coffee in a cup, you may consider buying this. Such cups come in handy if you are outdoors and do not want to carry a cup with you separately. Make sure that the cup is made of the same material as the thermos and can effectively retain heat.
Some thermoses feature corks to keep them closed but are usually not that effective and prone to leakages. Instead, screw caps are a better option because they stay in place. Overall, the lid should be secure as well as effective. It shouldn’t come off easily, should be easy to clean and resistant to leakage. It should tighten with ease and fit the thermos perfectly.
Make sure you check the return policy of the product if you are buying online. Sometimes a defective product may be delivered; you might get a broken lid that does not fit the thermos accurately. It’s not that the model itself is defective, but the specific product you got may be a defected piece, wrongly delivered.
9. Material Of The Thermos
The material of the thermos is another crucial factor and can have a tremendous amount of impact on its durability and effectiveness. As mentioned earlier, flasks made of stainless steel are common and popular as they are reliable, easy to clean, and offer great heat retention.
On the other hand, thermoses made of plastic or glass should be avoided as they are more prone to leakage, breakage, rust, and do not retain heat as well. You should also make sure that the thermos is well insulated. Double-walled flasks work incredibly well to keep your beverage hot or cold. Even a vacuum sealed thermos is a great choice to keep your coffee warm for a longer time.
10. Heat Retention
Heat retention refers to the amount of time a thermos can keep your beverage hot or cold. It varies from 4 to 5 hours to as long as 12 to 14 hours. If you plan on using your thermos for more than one meal or plan on sipping your coffee while hiking, then you will require a thermos which keeps your drink hot for a long time.
But if you intend to use it just for lunch or breakfast, as you rush through your morning routine, you won’t need significant heat retention. If you are looking for a thermos for both hot and cold beverages, then you need to check how long it can keep a beverage cold. You need to be careful, as some thermoses are not made for storing cold beverages at all.
Now that you know about the factors to keep in mind before you purchase the best thermos for coffee, it is time to check out some of the most popular thermoses available on the market. You’ll get a lot of choices when it comes to thermoses; of various sizes, colors, designs, and prices. You need to narrow down which features are the most important to you before shortlisting any product.
The products listed here are the cream of the crop. We also dug up customer reviews online to present a non-biased guide. The list covers both cheap and expensive thermoses, so that everyone gets a good option according to their budget.

FAQs on Coffee Thermos
Before you go ahead and make your purchase, here is an additional FAQ section to clear some last minute moment doubts:
1. How do you get rid of unpleasant smell inside a coffee thermos?
You can get that nasty smell out of your coffee thermos by using just two ingredients; vinegar and hot water. Just pour half a tablespoon of vinegar into the thermos, and then fill it with hot tap water. Seal the carafe by putting back its lid and shake it well. Let the mix rest in the thermos for 25 to 30 minutes, then empty it and rinse it a couple of times with regular water. Let the thermos dry for some time before using it.
2. Can you clean a thermos using bleach?
Not at all! You shouldn’t use bleach to clean a thermos made of stainless steel. Bleaching agents can prove very harmful when used on thermal flasks and thus need to be absolutely avoided. Before buying any model, check the cleaning instructions on its manufacturer’s official site. Some thermoses and lids are dishwasher-safe.
If not, it is recommended that you use a mixture of vinegar, baking soda, and hot water to get rid of unwanted stains or smells in your coffee thermos. It is advised that you watch videos that instruct you how to clean a thermos to not make any silly mistakes.
3. What is the best thermos to keep coffee hot?
There is no clear answer when it comes to listing the best coffee thermos. It depends on what an individual’s requirement and budget is.

Ideally, coffee should be served at around 180 to 185 degree Fahrenheit (if you follow the recommendations of the National Coffee Association of the USA). Other experts in this field recommend that at such a high temperature, the full expression of its subtle flavors is crushed. They argue that to taste coffee’s inherent flavors, like sweetness and acidity, it needs to be served at temperatures ranging between 120 and 140 degree Fahrenheit.
