Topic: coffee dosage, was Re: +sour notes in coffee? (19 msgs / 609 lines)

course.
I back-calculate my coffee amount from my chosen caffeine dose of 600.00 mg
per day. This works out to 10.1111 grams green coffee (8.5944 g roasted) per
12.0000 oz of water.
OK getting serious now, I just did an estimate based on number of brews per
roast. I probably have not changed the dosage much over the years. But this
is what works for my cowboy coffee which yields the strongest and best brew
of any of the methods that I have tried. Quite coincidentally, an estimated
caffeine content of 2% of the green weight comes out exactly 200 mg per 12
oz mug. Also coincidentally, this volume of whole roasted beans makes a
level fill in a standard 2 tablespoon or 30 ml measuring cup.
As for the decimal places, one of my former coworkers always expressed his
calculations in at least 6 significant digits, even though the raw data was
only 2 or 3 digits.

we are a bit on the strong side in terms of what we brew for general 
consumption here (in a technivorm). we use between 50-55 grams with 
32-34 fl ounces of water. So averaging it is roughly 10.5 grams 
coffee per 6.6 ounces water. wow, maybe we should back off a little. 
then again, it's personal preference and I like this brew a lot - 
doesn't have that liquor-like taste of too-strong coffee.
Tom
PS: we use the blue scoop we sell, the scaa scoop for measuring. i 
don't like tablespoons or other wide measuring spoons because the 
"heaping" amount above level is very subjective. Whatever you measure 
in, i think it is better if it is flat, not rounded or heaping. my 
.02 cents...

I've found that 4 level Technivorm scoops of beans produces about  
4-1/2 scoops of ground coffee, which makes a nice strong 1L. carafe.   
I can always dilute it to taste.

Last spring I asked this same question - ratio of coffee/water - and there
was a substantial discussion. The recommendations ranged from 1 gr coffee
/ 1 oz water to 1.6 gr coffee / 1 oz water. Tom is in that range, though at
the upper end: 55 gr coffee / 34 oz water = 1.6 gr coffee / 1 oz water.

I use 50-55 grams of coffee per liter of water, but I have gone as  
high as 60 g/L. With my Technivorm, I usually use 50 grams, but  
lately I have been using 53-55 grams. I almost always use 55 grams in  
my vacuum pot.
Normally I measure the coffee to the gram on the same scale I use for  
roasting. I did a quick test with my Technivorm scoop and Sandy's  
4-1/2 scoops comes out pretty close to 50 grams.
I have a collection of scoops from various places. The long-handled  
metal one I got from Intelligentsia makes the most repeatable  
measurements and is my favorite. I do not have the blue one from  
Sweet Maria's, but it appears to be very similar, albeit with a  
shorter handle.

Leo,
I fill my Technivorm with water to just above the "10" mark and I have a
metal 1/4 cup scoop that I use to measure the beans.  At least 3 level
scoops per pot of coffee.
Is that what you were looking for?
Hope this helps ...

I use 1/3 of a cup per full French Press. I think I weighed it once and it was well crud my mind just went blank sorry maybe I will wiegh it tomorrow eh? any thoughts on amount of coffee for an 8 cup cory vac pot. I just stole one at a local thrift store (grin) I am thinking I read somewhere it was 50 gm (or to taste of course) . if the cups were 4 oz then that would be pretty close to 1.5 gm per oz of water.

I always assumed that my 0.72 grams roasted per oz water (vs 1.0-1.6) was on
the light side, but not by over 100%. One thought is that I spent most of my
life BC (before coffee) drinking tea. So I maybe unconsciously brew on the
edge of overextracted and dilute. It seems like a good time to experiment
with the coffee/water ratio.

I just weighed a blue coffee scoop of beans and it was
about 10.8 gr if that helps.

Is this for a single scoop or is it an average of multiple scoops?

10.8 grains!  That's just a pinch of coffee. You must like your coffee =
very weak!

1.00 gram = 15.4 grains

That's for a single scoop and it should be grams g. Thanks
for the correction in the other message.
I just weighed a less dense bean and it came out to 10.1 g.
So there's a pretty wide variance when using scoops. And in
that small of a scoop it's difficult to get exactly the same
amount of beans each time. I suppose that's why anal retentive
people like me use a little scale.

You will get a few tenths of a gram deviation over multiple scoops even with
the same bean. It is better to measure out 5 or 6 scoops and calculate an
average using the total weight and the number of scoops. I use a scale at
home, but knowing the weight for various types of scoops is useful
when traveling and a scale is not available.

I only weigh the beans if I am making a small amount of coffee.  For a
9-cup morning  pot of coffee, I use 1 and 1/2 scoops of decaf (Harar)
plus 3 scoops of whatever regular coffee I am brewing that day.  I
know that I'll be getting somewhere between 44.4 and 45.6 grams total
coffee. On the average, it'll be "real close" to my 45 gram target.
And that's close enough for me!
