Topic: Coffee Crema Extraction Times (4 msgs / 66 lines)
1) From: Mark Neuhausen
It is nice to learn that an old dog can indeed learn new tricks.  I started
the low and slow barbecuing about three years ago, espresso coffee 18 months
ago, and now the fresh roasting of the coffee beans.  My daughter brought
back a couple pounds of organic shade grown beans from Ecuador that got me
more interested and then over the edge.
I really like coffee crema because of the ease to make it with an espresso
machine.  Just fill the cup two-thirds full and I'm done.  But I had noticed
that the taste was more bitter than espresso from the same beans, and saw a
comment in this newsgroup about over extracting.  In rereading the coffeekid
last night for something else, I saw that the coffee crema extraction time
is to still be the 20-25 seconds, just like espresso.  Duh.  Of course.
Just enjoyed an excellent coffee crema today from some Indian Monsoon
Malabar AA full city that was delicious with no bitterness.
I must admit that the quality of my life has significantly improved since I
got interested in food and coffee.  And I really do enjoy being a gourmand
rather than a gourmet.

Mark, So what did you change to get the additional volume of water but in
the same time?  Coarser grind?  Dan

I do not know about Mark, but a coarser grind was my solution to bitter 
Cafe Cremas.  If you use the fine grind I do for tampless espresso, it 
produces a rather overextracted Crema.

This is a multi-part message in MIME format.
I kept the same grind, and just polished the surface of the coffee with =
my tamper.  I use a Solis Maestro and have gone one grind coarser than =
they show for espresso so that I can tamp at about 30 lbs to get a 20-25 =
second extraction.  The same grind and no tamp gives me about six ounces =
in the same time period.
And if Santa is good to me, I will have to learn what is the correct =
grind for a French press (coarsest setting per the grinder's =
instructions) and for a vacuum pot (I assume the drip setting).
