It matters because the actual coffee flavor is extracted from grind better at higher temperatures. I'm not a scientist but I trust those that have done the research and they say that the optimal temperature for hot water in a coffee pot is between 195-200 degrees or just a little under boiling.
Coffee brewed below this temperature is thin and sour. Coffee brewed above this temperature is bitter and acidic. Hot coffee is normally held in serving pots at 180ÂºF. The recommended initial temperature in the cup is 170ÂºF and, as we all know, is too hot to drink. Coffee is either cooled by adding cream or by waiting for a few minutes before drinking.
