1Zpresso J-Max — frequently asked questions
Is the 1Zpresso J-Max a manual or electric grinder?
The 1Zpresso J-Max is a manual hand grinder with 48 mm conical burrs.
How much does each click change the grind on the 1Zpresso J-Max?
Each click on the 1Zpresso J-Max changes the grind by about 8.8 microns, so you can dial in small steps.
What grind sizes can the 1Zpresso J-Max produce?
At its coarsest the 1Zpresso J-Max reaches about 1400 µm, covering 20 of the brew methods we chart. Its finest setting isn't published, so we don't state one.
Can I copy grind settings from another grinder to the 1Zpresso J-Max?
Not directly — every grinder's scale is arbitrary, so a number that works on one model won't match the 1Zpresso J-Max. Match the micron range instead, using the chart above.
