Steep
Method
01Grind coarse
Like kosher salt. Too fine and the press silts; too coarse and it tastes thin.
02Heat the water
93°C — just off a local boil. If it was a rolling boil, let it sit about 30 seconds.
03Bloom, then fill
Wet the grounds, stir, wait 30s. Then fill, lid on, plunger up.
04Steep 4:00
Leave it alone. No peeking, no extra stirs.
05Plunge slowly
Steady pressure, about 15–20 seconds. If it fights you, the grind is too fine.
06Pour now
Don’t let it sit on the grounds. Decant the pot and drink it while it’s sweet.

Hot water added in the cup after you plunge — same extraction, gentler cup.

Sweet spot for most roasted coffee.
Grounds keep about twice their weight in water. Pour off when the timer ends.
