I tried 15.5g for water level 4 (weigh it next time) and at a 15 grind on Rancilio Rocky. 15 was too fine (it was not the size of sea salt). I didn’t time it exactly because I was fiddling with the equipment and this was my first attempt (don’t read anything into that). Next time I’ll do better. The cup was a bit bitter but it was definitely cleaner. Must try the 9 minute french press technique.
I tried it again: 16g on 25 grind (or was it 20?). I weighed the 220g of water. I still brewed it a few seconds too long because I was fiddling with the initial stir and creating the vacuum seal but it was much better.
