Topic: some specifics for cupping (5 msgs / 140 lines)
1) From: John
This is from Boyd's Coffee and certainly differs from the approach I've
been using. I think I'm going to do this with our next cupping and see
how everyone reacts.
Cupping
 Cupping is the traditional procedure in the coffee industry to evaluate
the quality of sample of green coffee. Individual cups of varietal
coffees are prepared according to established guidelines. The purpose is
to compare the samples with the buyer's needs for roasting and blending,
or to match the quality of a sample to a stated purchase agreement. At
least two samples of each coffee are compared for consistency and
likeness.
 Blends of roasted coffees are also cupped. The formula of coffees used
in a blend may change from delivery to delivery, so blended coffees are
cupped to assure that the "blend profile" is consistent.
 
To cup coffee: 
Prepare a sample by placing 10 grams of fresh-roasted ground coffee in a
cup that holds 6 fluid ounces.
 Smell the aromatic components released from the sample to evaluate the
dry aroma
..
 Pour nearly boiling water over the ground coffee.
Smell the aroma from the cup immediately after adding the hot water.
Let the sample steep for 3 to 5 minutes, then stir briefly.
While stirring the sample, take a long, deep sniff to evaluate the wet
aroma
Skim and discard the coffee foam from the surface of the sample. 
Take a spoonful of the beverage into your mouth and slurp it to spread
the fluid evenly across the tongue and into the back of the throat,
covering your entire palate.
 Hold the brew in your mouth for 3 to 5 seconds and then spit it out.
Slid your tongue across the roof of your mouth to evaluate texture of
mouth feel.
 The four standard characteristic evaluate by cupping are aroma, flavor
acidity and body. Very specific terminology is used to evaluate those
characteristics. Note, acidity in coffee is a desired flavor
characteristic that adds sparkle and vitality to the beverage. 
 Example, aroma can be descried as floral, spicy, fruity, winey, sweet,
woody, nutty, musty or earthy. Flavor can be sweet, fruity, sour,
bitter, rich, smooth, sharp or balanced. Acidity can be bright, vibrant,
sharp, thin, mild, flat or neutral. body can be full, thick, heavy,
buttery, thin, medium, flat or neutral.

I followed that procedure a couple times after reading up on 'cupping'. One
thing it didn't mention was tapping the grounds, which tend to form a crust
on the top, after infusion to aid their settling to the bottom. But seems to
still be a problem, for me anyway, grounds getting slurped with the brew.
I've switched to multiple Press pots for cupping comparisons. May not be the
'official' cupping method, but seems to work fairly well.

The thing that most attracted me was the consideration of the dry aroma
and appearance. The slurping has been a part of our cupping already
since we have a couple of olive oil gourmets in the group.

Smelling the dry grind is definitely part of cupping and the sensory
enjoyment in day to day brewing. Slurping technique or not slurping wasn't
what I was alluding to. I find myself doing it sometimes just drinking a cup
of coffee (much to Debi's displeasure, especially if we have company:-) It's
the slurping of the grinds themselves that are still in the brewed samples
while doing the cupping the traditional vs. Press way!

Ah, the light comes on slowly (the electric bill climbs) and I finally
get it. My problem is my two French Press are large (as in electric bill
size) but I can now justify buying a couple of tiny guys at the grand
opening of Barnes & Noble next week in McAllen (We're big time now folks
we have a Strabucks!) and it will prevent Carolyn from spending it all
on books!!
