If I'm in the mood, I put the (other 5 cups of) coffee in a thermal carafe. If I am lazy (usually), I reheat as needed in the microwave. Reheating coffee and popping corn are the two biggest uses of that electricity hog. Now comes the Too Much Time part.
My microwave has a built-in turntable. Since I like the handle of my cup to "arrive" at about 3:30 or 4 o'clock when the coffee is heated, I actually did some timing. My turntable rotates at 1 revolution every 44 seconds.
Heating cold coffee: 132-sec = 2:12 = 3 revs
Heating freshcoffee: 22-sec = ½ rev
On my microwave, these times deliver my cup of coffee the way I like it (150ºF /65ºC). I don't have a probe for my microwave so I kept my instant digital thermometer on the ready till I got it down. My coffee maker brews at about 150 but the addition of cream and a cold coffee mug brings the temp way too low for a good cup of coffee.
When I nuke a cup directly from the coffee maker, I put the cup on the turntable over at 10 o'clock and it is delivered at 4 o'clock. Ya see... at 4am I am not equipped to locate the handle of the mug that easily. I'm lucky I remember the coffee is in the microwave if I miss the beep!
Speaking of morning grogginess...
- has anyone else poured the ground coffee into the water door rather than into the filter basket?
- has anyone else poured fresh, steaming coffee into the sugar bowl instead of the mug?
