Is It True That Reheating Coffee Makes It Taste Strange?

No, but it can produce compounds that can change the taste of the coffee.

Coffee can taste different when you reheat said coffee because of the chemistry between the compounds in your coffee, precisely a combination called furfuraldehyde. This compound can cause the amino acid proline to change how it tastes – proline can make a tomato taste nuttier or pineapple taste sweeter. Reheating your coffee can release enough heat from the liquid phase of water molecules in your mug to drive up its temperature and produce furfuraldehyde that can give off this unique flavor.

There’s also another possibility worth thinking about – maybe something else happened while you were microwaving before drinking it again out of habit? The microwave can cause chemical reactions between other molecules in whatever food or drink you’re heating up and can be a little unpredictable.
