Coffee Thermos FAQ
How does coffee thermos actually work?
Do you prefer to bring your lunch from home?
If you do, then you’ve also notice that it’s hard to keep hot things hot and cold things cold… Unless you have one of those magical devices.
So what are these magical devices?
Thermoses, of course. And they definitely are magical when you think about how they can keep things hot and cold for extended periods of time. There is however a science to this.
If you have ever used a thermos before, you already know what we’re talking about. If you have filled it up with hot soup in the morning, you’ll be able to eat hot soup at lunch.
Likewise, if you fill it up with a cold drink, a cold drink will remain cold for hours later. So what science is this?
Well, the science behind this magical temperature retaining ability is a vacuum.
No, it’s not the kind that you use to clean your floors, however, it’s the kind that simply means the absence of air.
Thomas is basically a bottle with a double-walled container inside it. The air between both these walls is sucked out to construction creating a vacuum.
Instead of containing some kind of heating element to keep things hot or Thomas is designed to keep things hot but not long heat to escape.
Heat can be transferred through the air and to keep heat from escaping you need insulation. The best insulator possible is a vacuum because there is no air.
So there’s no air to transfer heat, heat is retained and kept exactly where you want it, which is in your drinks.
Thermos also keeps cold things cold in much the same way. It doesn’t contain any kind of cooling device, however, the same vacuum that keeps things hot also keeps things cold.
The heat that might otherwise transfer to the cold contents of the thermos is prevented from reaching it because of the vacuum between the double walls.
Thermoses today are constructed from more sturdy materials and it was years ago.
The first thermos featured metal exteriors with glass interior walls and these thermoses often end up getting broken when they were accidentally dropped.
Modern thermoses, however, are made up of interior plastic that helps reduce heat transfer. Some of them contain layers of Styrofoam that reduce heat transfer even further.
So if you use a modern-day thermos, then you can fairly and certainly, hours later enjoy hot soup or cold lemonade.
Is thermos safe to use?
In some parts of the world, enjoying certain drinks such as Yerba Mate is a part of the local culture.
So in this case, it is not unusual to see people moving around with thermos.
In fact, they make faithful allies that allow you to enjoy a hot drink virtually anywhere be it at work, the beach, the park, or between your traveling sessions.
One of the most popular types of the thermos is aluminum ones. This is because they are durable and practical.
The shockproof aluminum thermos was a welcome substitute to the previous, more widely used glass interior ones.
The sad reality is that high-quality aluminum thermos flasks are expensive and the market is now flooded with products made out of cheap and more budget-friendly materials.
Unfortunately, cheap steel thermoses are not resistant to the corrosion caused by hot water.
As time goes by, the impurities from the corroding metal are transferred to the water and this leads to certain health complications.
Therefore thermoses that are made from cheap metals should be avoided at all costs.
Stainless steel thermoses are probably the highest quality and the best possible flasks out there.
However, those that are made from low-grade steels are usually 15 times cheaper than higher-quality ones and are not suitable for food contact and contain impurities in the composition such as mercury and lead.
So if you’re going to invest in a thermos, make sure that it is made from safe stainless steel material and is BPA free.
How long does thermos keep coffee hot?
If you’re wondering exactly how long a thermos can keep drinks hot for, you are not alone.
Depending on the type of thermos you are using, the materials it is made from and obviously, the quality of the product, the heat retention times will vary.
However, when investing in a good thermos bottle, it should be able to keep your hot beverages hot for approximately 6 to 8 hours.

The mixture should sit in the bottle for a couple of hours, thereafter, you should scrub the bottle and lid as well.
Not only is the solution good for cleaning but it is just as good at removing odors that soap and water usually cannot.
