acc. I used to turn off the coffee pot after it made coffee

and warm up what i needed next in a microwave.

These days I use a (hard) insulated cup with a lid and warm up whatever i need on the stove.

I introduced my son to grinding his own beans. So he thought I was being a specialist.

He frowns on my use of a jug-cup and rewarming on the stove.

Hell I got so used to waitresses (27 years) keeping my coffee warm that

I don't like coffee cooling off anymore.
