I know you’re not supposed to reheat coffee in the microwave, but I learned some time ago that we can take, say, two-thirds of a mug full of microwave re-heated coffee, mix in some of the original brew, and the taste comes out pretty good. Now I’m thinking the whole “don’t reheat in the microwave ” thing needs to be reconsidered, freshly studied. It definitely changes the taste of the coffee. That’s true, but I believe some coffees might come out better than others. I just reheated a cup of coffee that I had thought tasted a tad bitter out of the pot, and I’m thinking the taste improved with the microwaving. Too many variables for me to commit even to a hypothesis at this time, but I think there needs to be some research.
