Sometimes it is unavoidable that the freshly brewed coffee cannot be enjoyed immediately, but only later or at a different location. And this is exactly where the thermos flask comes into play.
Coffee tastes best when it’s fresh and hot. But is it advisable to keep coffee in the thermos?
Maybe you feel the same way: you just can’t find good coffee on the go. It is immensely important for a successful start to the day that you get a delicious cup of coffee in the morning. So what to do? The simplest solution is probably to take your own favorite coffee with you from home. Then you finally know what you have. But what if you want the coffee to stay warm for a long time? Clearly: thermos flask or a practical thermal mug for on the go. But there are huge differences. You should pay attention to this if you want your coffee to be brewing hot for the second breakfast.
How do I recognize a good thermos flask?
A good thermos not only keeps hot drinks warm for a long time, it also cools cold drinks for hours. Also important: the vacuum jug should be leak-proof. Because hardly anything is more annoying than when the nice coffee spills over the documents for the meeting in the early morning. It is also very practical if the heat from the drink in the thermos stays where it belongs, namely inside and not outside and warms our fingers. When buying a new thermos flask, you should also pay attention to the pollutant content. Again and again, thermos flasks stand out due to a very high level of pollution. It is therefore best to ask your specialist dealer specifically.
Which thermos is right for me?
Which thermos flask suits you is not so easy to answer. To do this, you first have to know what purpose the thermos flask is supposed to serve. If you would like to drink your home-brewed coffee in the morning on the way to work, a thermal mug with a capacity of 0.4 liters is probably the right one. If the coffee pot is always ready to hand on the desk, you are well advised to use a vacuum jug. But if you are looking for a jug with a really large capacity, because Sunday visitors are expected, you should reach for a classic pump jug.
Good to know: This is how a thermos flask is constructed.
In most cases, a thermos consists of an inner and an outer shell. The outer shell, which consists of glass in most cases, is usually double-walled. In order to be able to keep the heat really well, the air is removed from the space between the two walls (vacuumed). Since there are now hardly any molecules in this space, the heat can only be emitted very poorly and stays inside. The inner shell usually has another layer that works like a mirror. Thanks to a special material, the heat is actually reflected and can therefore also be better kept inside.
