Green tea brews best at 70–80°C — boiling water makes it bitter. Set the CALM Kettle 27450 to 70°C or 75°C for a perfectly balanced, non-bitter cup. How much quieter is it than a regular kettle? The CALM 27450 holds Quiet Mark certification — independently tested and verified to be significantly quieter than uncertified kettles. Noticeably calmer during boil, ideal for early mornings and open-plan living. Can I turn the sounds off? Yes — the soothing soundscapes are entirely optional. The CALM Kettle works as a standard variable-temperature kettle without them. Does Keep Warm hold my chosen temperature? Yes — once boiling is complete and your set temperature is reached, Keep Warm holds the water at that exact temperature for up to 15 minutes. What's the best temperature for pour-over coffee? Most speciality coffee is best brewed at 92–96°C. Set the CALM Kettle to 94°C for an ideal starting point — the precision of the 5°C increments lets you dial in your favourite extraction.
