When I pulled my shot this morning it was topped with a good half inch
of crema. But while I was grinding the coffee for that shot the knob
fell off my forty-three pound grinder and in the time it took me to
get the knob back on and turn it off it ground enough for a second
shot. Well I am getting low on greens, I will order tomorrow, so I
decided to go ahead and use the extra ground coffee for my afternoon
shot. Low and behold: No crema. Doesn't taste as good either.
Anyway a imputed correlation based on an N of two, which should not
be calculated because N is less than three, a loss of crema predicts a
loss of flavor.
