There’s almost no drink that’s made better with boiling water. At boiling point, things burn and things get bitter.
The goldilocks “just right” temperature for most hot drinks are 10-20 degrees cooler than 100 degrees Celsius. The teas are sweeter, and the coffee richer.
Stopping the kettle earlier, or having a variable temperature kettle, makes hot drinks orders of magnitude better.
Tiny margins can make a huge difference. Especially at boiling point.
