I don't know your machine, but if you go to www.davidlebowitz.com, David
went to Illy's university of caffé and did a terrific article about the
science of coffee and why things do or do not happen. Just go to his site
and search on Illy or espresso and you'll learn a lot. As I recall, it had
to do with pressure and the time that the steam spent on the coffee.
