We got in the office some kind of coffee-machine, I think it's Moccamaster CD Thermo, and it has 2 thermoses, to keep a coffee warm/fresh for certain period of time.
Thermoses are good and easy to use. I think they do great job in terms of electricity economy... But does it really good for a coffee quality? According to the specs, they say, it's keeping temperatures between 80°-85° and meeting the requirements of the ECBC/SCAE/SCAA, what does it really mean? It may be there are facts, which I haven't found, rather than too broad explanations, or opinion based thing.
I understand, that caffeine is not burning at temperature coffee is left at, and it does not evaporate. But for how long it's acceptable to keep coffee in thermoses, without loosing the taste/smell and quality of coffee?
