What is the temperature of coffee in coffee makers?

The only way to answer this is to brew a pot of coffee and take its temperature. The most important information is not the temperature of the brewed coffee, but the temperature of the water doing the brewing; which should be between 190- 205* F. Any colder, and the coffee grounds will not release enough of their inherent flavors. And any hotter, the coffee will be over extracted, releasing unpleasant, bitter flavors into the final product.
The check the brewing temperature, place a digital thermometer into the stream of water from the shower head, and wait at least fifteen seconds for an accurate reading. (Do this without any coffee being brewed) If the temperature is too cold, buy a new machine. Or you could use a Coffee Press instead--the coffee is richer, thicker, and the temperature is controlled by the user.
