http://thermal-carafe-coffee-makers.info Get yourself a thermal carafe coffee maker and you won't have to put up with that ugly burnt flavor that coffee gets after sitting in a glass carafe on a heated burner for a couple hours. The thermal carafe helps your coffee retain its heat for a long time. If you use the basic carafe that comes with your cofee maker, it will probably maintain heat for 4-6 hours. But you can buy more advanced stand a lone units that keep it hot for as long as 24 hours.
