Strictly speaking, one shouldn't boil (100°C) water to make coffee†. The SCA recommends a water temperatures of 200°F ± 5° (93.0°C ± 3°): * https://sca.coffee/research/protocols-best-practices https://sca.coffee/research/protocols-best-practices Of course the temperature you make coffee at, and the temperature you serve coffee at, and the temperature you drink coffee at, may not all be the same. One should also keep in mind the serving container: some retain heat more than others, and so the temperature drop gradient may be different and should probably be considered as well. † Making (black) tea is something else.
