The shape of this dial

The top line is the universal grind index every BrewMark recipe uses. The bottom line is the JX-Pro’s own dial. The connectors show how one maps onto the other.

Where the lines bunch, the dial is compressed — small moves count for more

Settings by brew method

Start at the recommended setting, brew, then move within the range by taste. Sour or weak means go finer; bitter or harsh means go coarser.

1Zpresso JX-Pro grind settings for espresso, moka pot, AeroPress, pour over, drip, Chemex, French press and cold brew
Method	Setting	Range
EspressoFine. Aim for a 25–30s shot and adjust from there.	68 clicks	40 clicks – 105 clicks
Moka potFiner than filter, coarser than espresso. No tamping.	112 clicks	105 clicks – 116 clicks
AeroPress (short steep)For 1–2 minute recipes. Go coarser for longer steeps.	118 clicks	116 clicks – 119 clicks
Pour over — V60 / coneThe reference point for most published pour-over recipes.	120 clicks	119 clicks – 126 clicks
Pour over — flat bottomKalita, Orea and similar. Slightly coarser than a cone.	126 clicks	121 clicks – 138 clicks
Drip / batch brewAutomatic brewers. Coarser to suit the longer contact time.	134 clicks	126 clicks – 152 clicks
ChemexThe thick filter needs a coarser grind to avoid stalling.	152 clicks	138 clicks – 170 clicks
French pressCoarse. Too fine here is the usual cause of a muddy cup.	179 clicks	168 clicks – 186 clicks
Cold brewCoarsest setting you have. 12–18 hours of contact.	192 clicks	186 clicks – 200 clicks

Curvesplineconical burrs, fitted with a monotone curve

That is the resolution you actually have to work with on the JX-Pro. Where the number is small, a single step moves the cup more than you would expect — so change one at a time and taste before moving again.

Dialing in the JX-Pro

External adjustment makes this the easiest hand grinder to actually dial, because you can count clicks without disassembling anything. Its filter range is generous, which is a mixed blessing — small click changes do less than you expect at the coarse end and more than you expect near espresso. Move in larger jumps for French press, single clicks for anything under filter.

Convert a grind setting to the JX-Pro

If a recipe quotes a setting for a different grinder, this maps it onto the JX-Pro’s dial using the same curve the chart above is built from.

How these numbers were worked out

Every grinder gets mapped onto a shared 0–100 grind index, where 0 is espresso-fine and 100 is the coarsest useful setting. Five reference points on the JX-Pro are placed on that scale — espresso, moka, filter, French press and coarse — and the settings in between are interpolated.

The JX-Pro’s five reference points have been checked against the manufacturer’s published grind chart and cross-checked against an independent source, and that check is written down in the repository. It is one of 46 models, out of 78, where that is true.

Because the JX-Pro uses conical burrs, the curve between those points is fitted with a monotone cubic spline rather than straight lines. Conical burr dials are rarely linear, and the spline guarantees the curve never doubles back — a coarser index always produces a coarser setting.

The result is that “medium-fine” resolves to a real number on this grinder rather than a vague instruction. It is a starting point, not a guarantee — burr wear, bean density and roast level all move the target, which is why every row above gives a range as well as a number.
