Topic: grounds per amount of water (8 msgs / 160 lines)
1) From: Brandon Kolbe
Hello all,
     I have been lurking for some time and have finally felt the need to
come out of hiding.  I thoroughly enjoy all the information I have picked up
from the knowledgeable people on this list.  I believe it was last month
there was a thread about how much coffee to use per amount of water.
Unfortunately, I am a little confused.  I normally use six 1/8 cup measures
(which should be equal to six of the "blue scoops" from SM)  for 1.5L of
water for my Melitta manual drip maker.  I decided to weigh the six scoops
of coffee today to find out what the actual weight of the coffee was.  The
weight of the coffee came out to approx. 55g.  ( I only have a cheap analog
kitchen scale so I am unsure of the accuracy) which would come out to
I have been curious about how the scoop would contain 7.25g of coffee.  I
understand that the scoop is approx. equal to 2 Tbsp.  Is there an
understood amount of coffee weight per volume?  I guess what is really
confusing me is... grams is a weight and Tbsp is a volume.  Does the weight
of the coffee vary a lot based on the level of roast?  What is the preferred
method of measuring coffee for your brewing methods?   Perhaps I am making
it more complicated than it needs to be...
Happy Roasting!

Welcome to the list!
Someone else may be able to give you a more scientific explanation, but the
bottom line is that you should use whatever tastes best to you.  Presently,
I don't weigh my coffee before I brew, as I'm sure many have, I just know
how much should go in there.  I use a 1/4 cup stainless measuring scoop and
three of them go into the grinder.  For some beans, the scoop is perfectly
level and for other coffees the scoop is over-filled a bit.  This morning,
the Columbian was overfilled a bit and the Yirgacheffe was perfectly level;
both are excellent.
To answer your question, there are a lot of thing that can change the weight
from bean to bean including roast level, origin, density, etc.
Probably not exactly what you were looking for, but I hope it is somewhat
Again, welcome to the list!

A good place to start is 1 gram coffee per fluid ounce water. Then
adjust to your own tastes.
One shaken level blue scoop will usually contain between 9 and 12
grams of whole bean roasted coffee.  The variation depends on which
coffee and how hard you have roasted it.  Small beans and peaberry
beans have a slighly higher "packing factor" as well, so that their
bulk density ends up a little higher. Roasting to darker drives off
more weight.
My usual method involves using one blue scoop for each "2 cups" as
indicated on the side of the coffee pot measure. This amounts to about
10-12 ounces of water. Another way to think of it is 1 blue scoop/mug.

I have most often seen recommendations of between 1gram and 1.5 gram per
ounce of water. That is a general guideline; for some bean types, you might
like 1 gram per ounce, while for other bean types you might like 1.5 gram
per ounce of water.

The SCAA recommends 55g/liter but IME that is usualy enough to choke most
auto drip coffee makers. Works great with press pot though.

Thanks to everyone for the replies.  I am glad to know that the amount of
coffee I use seems to fit in the ballpark with the SCAA guidelines.  If I
was way off I would be willing to adjust the amount of grounds that I use.
Of course, what ultimately matters is my own personal tastes (as has been
pointed out to me).  Also, thanks for the links.  I have found them all to
be very informative.
Happy Roasting,

I was always confused with this.  The SCAA blue scoop that is two
table spoons, should you use that to measure out whole beans or ground
beans?  When I brew both press pot and drip with swissgold filter I
use 1 scaa scoop (2tbs) of whole beans and then grind them.  Is this

Lurk not, lest ye become unknown as a Lurker.
I always used a volume measurement of 3/8 cup of beans in the blade grinder.
That's 3 oz by volume in whatever coffee brewer.
A 10 cup drip pot would get 4 - 5 oz, depending on how I felt after cleaning
up 7-11's equipment for them.
