Well, technically the steam has dropped in temperature by the time it reaches the coffee. The temperature in the kettle of an espresso machine is roughly 212°F, too. It has a longer way to reach the portafilter though, so yeah, the temperature is a little too high in a bialetti, but it's a great invention for easy to make coffee. A rustic one, but great nonetheless. The early espresso machines hit the coffee with 260°F steam, too.
