I am a big fan of tea and anything tea related, therefore I am also interested in water kettles, and Kenwood Response Kettle might have just become my favorite one. First of all, it lets you choose to end the boiling process at 80 degrees Celsius, which is ideal for brewing tea and best of all, its exterior gradually changes color from blue to red as the water becomes hotter. The Response Kettle, once it’s reached the desired temperature, can be set to maintain the heat for as long as you want, therefore eliminating the need to reheat when you need a refill.
