You know what would be really cool? Put the thing on a base about a foot high, turn the spout so it faces down and put a valve on it. Then you could set it at 200F, leave it on while dispensing the water, and it would hold the temp for the entire pour!
We should get a definitive answer on how much the water cools once the kettle's off the base and throughout the pour, and also the temps on the slurry during the pour.
