I am looking for a replacement for my coffee maker at my office. I used to have a nice, albeit cheap, machine that brewed into a glass lined thermal carafe. My wife went to clean it, and the lining shattered. She was kind enough to replace it, but with a stainless steel lined thermal carafe. This does not keep my coffee warm enough for long enough. By mid-morning I am sipping luke warm brew. I have searched the internet, but cannot find anything but steel lined. Does anyone have any suggestions on what equipment I should look into?
