Coffee is always the best when it is freshly made. However, coffee can be safely reheated and enjoyed even after it’s gone a bit cold. The important thing to reheating coffee is you want to be sure you don’t overheat or burn the coffee while it’s reheating.

It is important to note that coffee that has creamer or milk in it should be reheated as the milk can curdle or be soiled.

As we discussed above, coffee can safely be reheated on the stovetop or in the microwave. However, coffee can only safely be reheated if it’s plain black coffee.
