Set a 1Zpresso J-Max between 1.6.6 and 3.8.1 for pour over, per Honest Coffee Guide's compiled 1Zpresso J-Max chart; inside that, a V60 cone wants the tighter 1.6.2 to 2.8.4 band. Start in the middle of the window and adjust on taste: finer if the brew drains fast and tastes sour, thin or weak, coarser if the bed stalls, the brew takes far longer than usual, or the cup tastes bitter.
1Zpresso J-Max pour over settings, and the bands either side
| What | Setting on the 1Zpresso J-Max |
|---|---|
| Pour over window | 1.6.6 to 3.8.1 [1] |
| V60 cone, the tighter band inside it | 1.6.2 to 2.8.4 [1] |
| The AeroPress band on the same chart | 1.3.2 to 4.0.3 [1] |
| The French press band on the same chart | 2.8.1 to 5.0.0 [1] |
| Full grind range of the grinder | 0 to 1190 microns [1] |
The neighbouring bands are there for context. If your pour over 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 pour over wants this part of the dial
Pour over is percolation: water passes through the bed once, under gravity, and the grind sets how fast the bed drains. Drawdown time is the tell, and it is the number to watch before you argue with the taste.
Dial it in from the chart in 3 steps
1. Set the middle of the pour over window above and brew once, changing nothing else. 2. Taste against the two failure directions: finer if the brew drains fast and tastes sour, thin or weak, coarser if the bed stalls, the brew takes far longer than usual, or the cup tastes bitter. The full logic is in the pour over guide and the pour over ratio. For the rest of the recipe, see what to do when a pour over is too slow. 3. Move in small steps and write each attempt down; the free dial-in logbook exists for exactly this. Keep the pour pattern the same while you change grind. Pouring technique moves drawdown as much as a couple of settings do.
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. The full 1Zpresso J-Max grind settings chart has every other brew method on one page.
