I use a 2 minute steep time and a grind a little bit coarser than I =
would use for an electric drip maker 6 tablespoons of beans for 8 cups =
of coffee.

3) From: John Brown
i grind as fine as i can and still have resistance when i push the 
plunger down after a two to three minute wait for the coffee to steep.  
i become a coffee barbarian by decanting the rest of the coffee into a 
jar and put it in the fridge for latter.
the Porkert grinder make a very good grind for the FP, but not quite 
good enough for the Moka pot.
the Porkert grinder cuts the bean by two methods, first is the auger 
with a rough grind then the flat burrs that finish the grind.

Try a coarse grind in your French Press and compare it to your fine grind.  Think you'll be pleasantly surprised at the difference.  A little sweeter coffee.

"...some of the veterans on the list might shorten my learning curve."
That's half the fun, that learning curve- especially the ones coming
down out of the mountains on I-70, west of Denver Town. It's kind of
tight as it is if your dx/dt is very large.

RayO,
dx/dt ... that brings back some pleasant old memories!  I don't think =
I've seen
that written in years (decades?).  Calculus was one of my favorite =
subjects in
high school & college ... I probably have even used it some since then.  =
Thanks
for mentioning it!
BTW, don't you want to have a high 2nd derivative (I forgot how to write =
that!
dx2/dt2 ???) going into those curves ... that's where the fun is!   :)

8) From: Frank Parth
Dave,
That second derivative was written d2x/d2t. This is the formula for acceleration. As a physics/math major I had to 
learn a lot of that "material". And I remember it even after 35 years.
Ciao,
Frank Parth

dx/dt is just velocity, Dave. dx/dt (dv/dt) is acceleration. In simpl=
e
turns, you have dy/dt, + or -, depending on right or left turn. dx=
/dt is
referred to as "jerk"- the rate of change of acceleration. New drivers have
to learn the application of the clutch and brakes to keep dx/dt low.
It's not comfortable. dx/dt of a bullet is extremely high when you fi=
re a
gun or you're in a Corvair that hits an Oldsmobile wagon head-on (ouch!)
Sure bent up my  Corvair convertible and the Olds.
On glare ice, the (-)dx/dt wouldn't have been too great even pumping =
the
brakes as the witnesses stated. Sudden increase of deceleration when I hit
the southbound Oopsmobile.
Cheers and 73, -RayO, aka Opa!

I remembered the 2nd derivative being acceleration ... & I even came =

the notation.  Not bad for an old guy!  
I also knew about the 3rd derivative, although I don't recall the term =

It is relevant to this mailing list though ... my wife doesn't know a =

that is like i remember the square root of 2 [1.414] and 3[1.73]  of 
course it is not carried out to the last decimal

I learned calculus back in 1968.  Not really anxious to revisit that =
stuff.  I won't ask any more coffee brewing related questions here.  =
Sorry for intruding on the list.  I'll figure out the answers to my =
questions on my own.

Why?  you are as welcome as any body else.  ask away, maybe some  one 
has the answer

Please don't be put off by a wandering thread - 
doesn't happen all that often. I am relatively 
new to the list also, and I hesitated to respond 
to your post about brewing with a vacuum pot. I 
have only used my (new) Yama 8 cup pot a few 
times. I'm having to experiment also - but even 
when the coffee comes out a tad weak it is still 
a great cup. I am finding that I need to put in 
about 8 level teaspoons (whole bean) into my 
grinder and then filling it to the 8 cup line 
with hot water. I have been following Tom's 
recommendations for brewing times, about 1 to 
1-1/2 minutes before removing it from the burner. 
I think I may go to 1-1/2 to 2 minutes just as an experiment.
Love watching the process, though!
Let us know how things go - there are plenty of 
ideas and tons of experience on this list - I think it will be worth your=
 time.
Warm regards,
RG

15) From: Eddie Dove
Brian,
The Vac Pot Guru I am not, but I do have a Yama 8-cup, a Bodum 8-cup
and the Bodum eSantos.  I don't use them very often, but I do like the
brew I get from them.
I use the same grind I use for the Technivorm drip ( maybe more course
) and steep for 3-4 minutes depending on the coffee, but I use a glass
rod filter.  If you are using the Yama cloth filter, you can use a
finer grind and steep for less time.  Generally, I wait until all of
the water has traveled north before adding and stirring the coffee.
You may wish to try a courser grind and longer steep as it might make
for a sweeter brew of the nectar.
I hope this is helpful.
Respectfully,
Eddie

Tarvus:
I use a Bodem vac pot, but this should apply to your Yama as well.
Most places say extraction time should be from 3 to 5 minutes. Once
enough water has gone up to saturate the grinds extraction has
started. Extraction continues until the last of the water has gone
down. The time it takes for the water to go up depends on how high the
flame is. This will also effect the time between turning the fire off
and when the water starts down. The time it takes the water to go down
depends on how course the grind is and how much grinds there is.
I try to do things the same each time (as much as I can)changing only
one thing to see the effect it has. I started with 35 grams of coffee
grinding at the drip setting on a Solis Miestro. The trip up took
about 25 seconds(from enough water to stir the grinds to air bubbles
coming up). I waited one minute and turned the fire off. About 30
seconds later I saw brown in the bottom. About 45 seconds later it was
sucking air into the bottom. The coffee was good but a bit week, so
next time I increased to 40 grams, then 45, then 50. Each increase
resulted in an increase in the time for the trip down and finely
resulted in stalls. I was not able to use that much coffee until I got
a Rocky grinder.
You should have no problems with your Zass.

better cup than a fine grind and 6 tablespoons?  Obviously I will =

What is a better cup?
That depends who is doing the tasting. Many would tell you that it
would be espresso. I would say it doesn't get any better than I make
in my vac pot, others would say something else. You will have to
decide for yourself.
