1Zpresso J-Max: espresso grind setting
Start at 100 clicks from zero for a medium roast. Finer is fewer clicks.
Where to start
- Light roast: 96 clicks from zero. Medium: 100 clicks from zero. Dark: 104 clicks from zero.
- Usual espresso range: 70 to 145 (clicks from zero).
- One small step: 2 clicks from zero, about [object Object] µm of burr movement.
- Zero point: Zero is the first resistance turning toward fine, not the tightest point (1Zpresso); units vary by up to 10 clicks, so shared click counts are approximate.
The light and dark starting points are two small steps either side of the medium one: our rule of thumb, not the maker's.
