I forgo the coffee machine at work and brew my own as well, but just brew a fresh cup on demand, hobo style. Keep grinder, beans and vacuum sealer in an unused kitchen drawer. I never had much luck with thermoses. They seem to "cook" the coffee and give it a burnt, unfresh flavor after a while. Do you run into that?

I haven't experienced that, at least not that I'm aware of. My coffee only really tastes "cooked" when left in the pot on the hot plate too long.
