This is interesting. They seem to do the inverted method with the AP but are a bit light on the details (as you'd expect). But only use 12g of coffee?
I've always been aiming for 18g, but more often than not end up more like 20g. What's recommended for AP? I also weigh my beans once ground, do you think there is a difference between weighing whole beans, and ground beans?
I settled on the following:
"normal" way up AP with dry filter (i.e. no pre-soak)
18g scoop of beans (usually this means a level scoop using the AP provided one).
Grind medium-fine. For reference: it took about 180 rotations of my hario skirton to grind it. The "setting" was 1/3rd of a turn of the holding screw from the biting point.*
Dump into AP and rattle to level it out - doubt this makes any difference..
Boil kettle and wait for all bubbles to stop.
Pour into AP up to the number 4 mark.
(using AP stirererer thing) do ten back-forth north-south, then turn 90 degrees and do 10 east-west. OCDlulz.
Wait for water to filter to number 2
Press remaining water out with a slow press of about 20seconds.
Who process takes about 10mins.
The bestest best I've had from my AP is an inverted brew for 20mins. But I don't have the patience.
*by this I mean tighten until you feel it "bite" then unscrew for 1/3rd of a rotation.
