Why does reheated coffee taste bad?

Reheated coffee tastes bad because reheating changes the chemical composition of the coffee and totally impairs the taste of the beverage. While most of the flavor is fixed in place when your personal coffee is brewed, reheating will restart the reaction and result in a flavor change.

Even inside the thermos, the drink starts to “spoil” and should be discarded, especially if it has sugar.

You can store your coffee in a thermos – unsweetened, of course – but not for long. It can be used if you are suddenly working and don’t want to get up all the time to get coffee. But, as said, it should be consumed as soon as possible, even if it has been placed in the bottle right after preparation

Although it is a very common practice among some people, it brings short-term health harm. Despite keeping it hot, this will only spoil its flavor, burn it, or accelerate its oxidation. 

In addition to causing the degradation of substances present in the coffee, responsible for the aroma and flavor of the drink, reheated coffee changes its characteristics of origin, leaving the drink with a bad taste, bitter in the mouth.
