How to Warm Up Cold Coffee?

Problem: Cold Coffee

Today, I made a great cup of coffee as usual.  I used my coffee grinder to make fresh coffee grounds from whole bean coffee.  I used filtered water, and brewed my coffee in a coffee maker with a cone filter for maximum flavor extraction.  Here are details on how to make a great cup of coffee.

I got distracted in my workshop, and found that I had about 1/4 cup of cold coffee.  I like my coffee hot.  I have tried heating up cold coffee in the microwave, but it tastes terrible.  What can I do to warm up cold coffee without making it taste bad?

Update June 1, 2015:  I tried some further testing of heating up coffee in the microwave- I found that if the coffee is still fresh (less than an hour old) and if you don't microwave it too long that it still tastes OK.  Still, I think adding hot water is the best way to heat up coffee, but briefly microwaving it can work too.

Solution: How to Warm Cold Coffee without Making it Taste Bad

When I end up with cold coffee that I want to warm up, I make a sort of "Cafe Americano".  I heat up a small amount of water to boiling, and add the boiling water to the cold coffee.  This does make the coffee a bit weaker, but the flavor is still good, and the coffee is hot again.

I use an amount of water slightly less than the amount of cold coffee.  For the cold coffee shown in the pictures, I microwaved the water for 1:30 to get it boiling a little, and then poured it into my cold coffee.  It was a little weaker than the original coffee, but still drinkable.  Give this method a try next time you end up with cold coffee that you want to warm up.
