1Zpresso J-Max french press grind setting: the verified range

As an Amazon Associate, Barista Life earns from qualifying purchases.

Set a 1Zpresso J-Max between 2.8.1 and 5.0.0 for french press, per Honest Coffee Guide's compiled 1Zpresso J-Max chart. Start in the middle of the window and adjust on taste: finer if the cup tastes thin or sour after a normal steep, coarser if the plunger fights you and the cup is muddy with sediment at the bottom.

1Zpresso J-Max french press settings, and the bands either side

The neighbouring bands are there for context. If your french press sits at one end of its window and still tastes wrong, the answer is usually a different variable, not another step in the same direction, because past that edge you are grinding for a different brew method.

Why french press wants this part of the dial

A French press is full immersion behind a metal filter, so the grounds sit in the water for the whole brew and nothing fine gets caught on the way out. Coarse is not a style choice here, it is what keeps silt out of the cup and the plunger moving.

Dial it in from the chart in 3 steps

1. Set the middle of the french press window above and brew once, changing nothing else. 2. Taste against the two failure directions: finer if the cup tastes thin or sour after a normal steep, coarser if the plunger fights you and the cup is muddy with sediment at the bottom. The full logic is in the French press ratio and the French press grind size chart. For the rest of the recipe, see French press tips. 3. Move in small steps and write each attempt down; the free dial-in logbook exists for exactly this. If the cup is gritty at the coarsest setting on the chart, the problem is burr alignment or fines, not the number on the dial.

How the 1Zpresso J-Max adjustment reads

The 1Zpresso J-Max uses an external dial read as rotation.number.tick at 8.8 microns per click. Find your zero before trusting any chart: with the hopper empty, close the burrs until they just touch, call that zero, and count from there. A zero point calibrated differently from the chart's shifts every range by the difference, which is behind most complaints that a chart is wrong.
