@indigo Oh pshaw. I had read about brewing at lower temperatures, and whn I got my Aeropress decided to use a little digital thermometer and be a human thermostat. But the kettle was leaking anyway; I had repaired it once with Sugru and that slowly deteriorated. It had reached the point where it leaked all over the counter, and rather than doa whole new Sugru, I bought a new one.
Moral: make your kettle leak first.
