Comment on Brewing Espresso with Ultrasonic Assistance by Elliot Williams

In reply to Mr Nobody.

Certainly there must be something more complicated that simply adding an ultrasonic actuator to the process.

Have you considered trying to reduce the unfortunate effects of gravity on the extraction process? I only drink espresso that's been extracted in freefall. By specially trained penguins, who because of their ear anatomy, don't vomit on the way down.

Sure, it's a little more complicated than just putting a filter in the cone. But the taste!
