But can you microwave coffee? Is microwaving the coffee good? Will the coffee get bad after that, and why?

The answer is yes, you can microwave coffee. The microwave is one of the most useful inventions of all time, isn’t it? We will show you the most proper way to microwave coffee.

I’m sure you also understand, never heat coffee in a microwave with a plastic cup. Learn more about microwaving plastic here.

After putting the coffee into a mug with a suitable material, place it in the microwave to set the heat level to medium. Do not let the heat level be too high. A little above medium is still acceptable.

Next, decide how long you should set the time. The time to heat coffee in the microwave depends on how much coffee is left in your cup. Usually, half of a full cup of coffee takes about 45 seconds. If, after 45 seconds, you are still not satisfied with the heat of the coffee, it is acceptable to reheat for another 30 seconds.

Please note that if your coffee has been added with milk or cream, it is necessary to check to see if the coffee is still drinkable. For example, if a cup of coffee with milk is left outside for hours in hot weather, it properly goes terrible, and you shouldn’t drink it anymore.

Best Way To Reheat Coffee: Stovetop

Although heating coffee in the microwave is quick and easy, coffee experts often do not recommend this method. Instead, if you need to warm up coffee, refer to the steps below to reheat with the stove.

Very simple, kettle, a pot, or a saucepan should be prepared – something you can put on top of your stovetop. Then, pour the coffee into it and set your pan on a burner.

Why Does Heated Coffee Not Taste As Good As When It Was First Brewed?

Of course, it will be hot again as you want, but this does not mean that your coffee will be as good as it was. When coffee is left outside for a long time and cools down, its chemistry will also change more or less. Attempting to reheat the coffee will break down the aromatics eventually.

Although coffee is famous for caffeine, its flavor is made up of about 1000 chemical compounds. Heating coffee after it has cooled will create chemical reactions that affect the taste of coffee. Therefore, after being reheated, coffee will lose its caramel-like flavor and become much more bitter.

3 Tips To Keep Coffee Hot For A Longer Time

Experts recommend that you avoid coffee that cools quickly after brewing in the first place. Here are three tips you can apply

1.   Keep your coffee hot with a thick scarf

Wrap this scarf around your coffee cup. You can also replace the scarf with a jacket or cloth, as long as it is thick enough to prevent your coffee cup from rapidly radiating heat into the outside space.

This is the most manual way and keeps the coffee warm for a short time, but it ensures that the coffee stays warm for longer without losing its distinctive taste.

2.   Use a quality thermos bottle

Thermos is always the first choice to keep any beverage hot or cold for a long time. Good thermos (and, of course, more expensive) can even keep your coffee warm for up to 12 hours.

A cheaper thermos can keep your drink warm for up to 6 to 8 hours. We think 6 to 8 hours is enough for a productive working session without having to get up to make yourself a new cup of coffee or reheat it.

However, be aware that there are many poor-quality thermos flasks on the market. Make sure the thermos you buy is from a reputable brand with expert testing for the best experience.

3.   Cup sleeves can also be handy

The cup sleeves help to insulate our hands from hot drinks and help keep the heat of them. There are many cup sleeves with many materials you can choose from: paper, knitted, or neoprene.
