Topic: How much caffeine is too much? (15 msgs / 627 lines)
1) From: Pete
Well, yesterday I went crazy roasting 3 batches of different beans.  When I 
was done, I made each one to see the difference in taste, out of the 
autodrip as well as expresso machine.  6 shots later, and about 3 cups of 
autodrip, and I found myself unable to goto sleep until after 2am.
That got me to thinking..... How much caffiene is too much?http://www.msnbc.msn.com/id/6631177/Thoughts?
I have always figured too much would be when my head explodes, but I guess 
others may think differently.  And whats this moderation business anyway? 
Pffft!

Evidently, we can safely assume that a possible answer is at least:
6 shots and about 3 cups of autodrip
:-)

Here is a data point for your caffeine question.
   I drink 3 to 6 full pots of coffee per day, every day.  The pot is a commercial BUNN 64 oz size.  I use a 
BUNN VPR machine that has been tweaked to provide water in the 204 degree range to the top of the 
basket at the start of the brew cycle.  Usually have a couple of cups of brew right before I go to bed.  I 
have no trouble sleeping

One must consider how strong they brew their coffee.  Most people who visit
my house dilute my TV brewed coffee by at least 1/3.  Three to six pots of
weak coffee can be handled better than one full pot of very strong coffee.
I am not making a disparaging remark about the strength of Rich's brew.  I
have no idea how strong he brews his coffee.  I just know that I have had a
lot of "brown water" in my day that has little caffeine in it.  They say
that espresso has less caffeine, but I know that 3 double shots gives me
more of a buzz than drinking a TV pot of coffee.  I make this comparision
because there is about the same amount of ground coffee in both.

I should have added that I brew the coffee to the point that I can not pass sunlight through a clear 
glass 12 oz mug of brew.  I like strong coffee.  Most people will not drink coffee that I have made.  I 
tend to like the flavor of the darker roast levels which does reduce the available caffeine though.

Pete,
Quantitatively, too much caffeine in humans is 150 to 200 milligrams per
kilogram of body mass.  See source below.
Fromhttp://en.wikipedia.org/wiki/Caffeine#Caffeine_intoxicationIn cases of extreme overdose, death can result. The median lethal dose
(LD50)
of caffeine is 192 milligrams per kilogram in
rats.[57]The LD
50 of caffeine in humans is dependent on weight and individual sensitivity
and estimated to be about 150 to 200 milligrams per kilogram of body mass,
roughly 80 to 100 cups of coffee for an average adult taken within a limited
timeframe that is dependent on
half-life.
Though achieving lethal dose with caffeine would be exceptionally difficult
with regular coffee, there have been reported deaths from overdosing on
caffeine pills, with serious symptoms of overdose requiring hospitalization
occurring from as little as 2 grams of
caffeine.[58]
[59] [60]
[61]  Death typically occurs
due to ventricular
fibrillationbrought
about by effects of caffeine on the cardiovascular system.

Les, 
I'm curious how many blue scoops you put in your TV for a 10 cup pot. And how fine do you grind. I use 4 blue scoops when I make 7 cups in my presto scandanavian. I think my grind is average (2 full turns on a zass). Does that sound like a strong brew in your book or is that brown water?

Reading that article indicates to me that all of us should increase
our consumption of Sweet Maria's coffee, which as I understand it, are
chock full of anti-oxidants!
Who's making a Harvey order?!?

It's different for everyone. It's like alcohol ("regardless of how  
much or how little you drink, if drinking causes you any problems you  
have a drinking problem")--if  after drinking caffeine you feel  
jittery, queasy or can't sleep, it's too much for you at that  
particular point in time.  Depends on what meds you're taking, how  
well hydrated you are, what your blood sugar levels are (fasting or  
reactive hypoglycemia--often caused by hunger or by sugar overload-- 
can mimic all the symptoms of caffeine overdose, except that the  
"hypoglycemia headache" is missing from the latter), other stressors  
in your life. I've gotten shaky and queasy after drinking a cup an  
hour while working nonstop 11-5 without food; I also can normally  
knock back a double breve before bedtime (having had a couple of cups  
of drip and at least a double shot earlier in the day) and still fall  
asleep before finishing my nightly silent prayers.  A friend of mine  
boasted once she could drink all the coffee she wanted at any time of  
day with no ill effects---we fed her an entire small moka pot full,  
took her pulse and B/P, and got readings of 68 and 110/65,  
respectively.  (She's a reporter and drinks seven cups or more a day).

My son had been complaining lately that I must be under-roasting my  
beans because the little 4-cup Mr. Coffee pot he's been brewing  
himself in the morning (with 2 heaping Technivorm scoops of grounds)  
gives him no "buzz" at all.  (He gets up before we do and doesn't  
want to use the Technivorm and leave half the pot over, nor does he  
want to brew himself an Americano though he pulls excellent shots  
when his friends ask for them).  I asked him how he was grinding, and  
he said whatever setting I had currently on the SMP.  I then opened  
up the filter basket lid and laughed myself silly:  the grounds were  
in a #2 paper filter cone.........which in turn was sitting in the  
Swissgold basket filter!  I pointed to the note I had posted directly  
above the machine: "Do not use a paper filter if metal mesh basket  
filter is present; if not present, use a paper basket-shaped filter."  
He sheepishly admitted he never checked first to see if the mesh  
filter was in there.  I took what was left in the little pot, poured  
it into a large mug, pulled a double shot into it and handed it back  
to him.  This morning he told me that after following my  
instructions, the coffee was finally strong enough. Duh.

Dunno about Les, but I use 4 heaping or 5 level  brown TV scoops per  
8 "cups" of water in my Technivorm.  Most people have to dilute the  
resulting brew.

Test the limit?  What limit?  I am just glad that if I get pulled over on
the way home, there isn't a blow test for caffeine!

I follow the TV instructions, and they say 'more coffee doesn't make the
brew better, it makes it worse'.  I also haven't disputed their logic, yet!
I am still choking the filter with coffee (tends to happen when I make a lot
at once, like 10c) with grinder (Rocky) set at +45.  Maybe my paper filters
suck.  Anywho, I am afraid to add more than the TV recommended amount as is!
