Use of dark, oily beans in Rocky RancilioI've read a few back postings, but can't get enough information to
make a presentation to DH regarding my desire/wish not to put oily
dark beans in the Sivlia espresso and Rocky burr grinder.
My arguments are:
I can taste dark-roasted and/or oily beans 'a mile-away.' If any
remains in the grinder or if the oil sticks to the grinder, I will be
able to taste it. Then there is the pyschological aspect of it; if I
don't taste it, I will be examining the taste of the espresso each
time I drink it to see if I 'can' taste it.
I feel that cleanliness will be a more important part of the use of
the Silvia due to the fact that each time it is brewed, the
portafilter will have to be washed vs. rinsing between two pulls of
the same grind. (He would be using it for his dark grind as well as my
light-medium grind.) One may ask why I would use light-medium roast
-- I like very strong coffee, hot as Hades, and with half-and half.
"Shallow Gold," they call it in Vienna, I believe.
Years ago I saw what dark oily beans can do to a grinder. I went
through several grinders, a couple of Brauns, as I recall. They were
always gooked up and would just give up. I realize that the Braun and
Rancilio has no comparison in operation.
When we bought the Silvia, DH felt that the Saeco (even though it
stopped working) was good enough. He didn't have to tamp, it which he
said he liked, and it always had good crema. He says he liked it
better than the Rocky - for covenience and taste. We have not had good
crema yet. He has tried surfing as suggested by coffeegeek and I
believe I had him convinced this morning to install a PID. (These are
things I cannot do - I can hardly pick up this new portafilter.)
However, later this morning he said that he had bought some dark oily
beans. Probably most of you feel that there is no problem with this,
but can you help me with a reason NOT to use oily beans other than I
have suggested; something that might appeal to an 'engineering mind.'
Thanks,
Humbly,
