I am currently using 40g coffee to 500g water which is 12.5g coffee to 1g water but I have seen things like this https://www.olympiacoffee.com/blogs/blog/how-to-brew-like-olympia-coffee#:~:text=For those of you who,use 16.7 grams of water. which suggest using a little more. Does it even matter to adjust the ratio precisely if I don’t have a precision grinder and am using a Krups blade grinder? I am trying to get things as precise as possible.
When I switched to pour-over, I didn’t want to futz with figuring out the proper ratio, so I bought a grinder that produces pre-measured amounts, and a pitcher with measurement lines. So I go with the “2 cups” measurement on both.
…and yes, I know that I’m doing it wrong. ;-P
If you like your coffee you are doing it right
