Definition
Kettle temperature is the easiest thermal input to set, but it is not always the exact temperature the water has when it reaches the coffee.
Why It Matters
It anchors the thermal workflow, even though later losses may change the actual brew temperature.
Page Context
Kettle temperature is part of the Brew Supply AeroPress Wheel and helps brewers describe the temperature set on the kettle.
