    I think it burns the oils.....  I know you can burn the oil in the beans when over roasting them.   Coffee has the oil in it, and I would suspect it burns in the microwave.  Hope this helped!

    I don't know, but it pisses me off!  No, just kidding, but it is annoying.  I think it's just because it's no longer fresh, but that's not a very helpful answer!

    If you are leaving it in too long it will evaporate some of the water making it stronger and if it gets too hot it changes the molecular structure and burns the oils.
    If it is yesterday's, or last week's, coffee it may be bitter to start with from having spent too much time before the coffee maker's heater shut off.

    Taste it before putting it in and try heating it for only the minimum length of time to get it hot enough to enjoy rather than close to boiling. Start with 1 minute for a large mug, then 30 second bumps if you want it hotter.
