You recently denigrated Starbucks, remarking that what they do to a bean is
criminal. Unfortunately, what I do to a bean is worse. I got myself a
Starbucks Barista machine, which makes coffee not as good as Starbucks
in-store coffee. It still makes me happy, yet I realize that I am distant
from the Coffee High End.

Are you familiar with espresso issues, ie., pressurized portafilters vs.
nonpressurized, how to avoid bitter shots, etc. ?
