    Reheating coffee doesn’t make it bad, be it in the microwave, on the stove or hot plate. Not finishing your coffee and letting it get cold just to reheat it later definitely makes it worse.

    This is not something subjective, oxidation is very real. If you don’t believe me, peel an apple and let it sit for the same amount of time as you let your coffee sit and then you will see the effects.

    When you brew coffee you extract all these oils and goodies from the beans thst have been protected by the antioxidants and expose them to air. While they will not turn to vinegar, they do oxidize and therefore degrade quite rapidly.
