Pepper Grinder Grinds Too Fine? How to Coarsen It

A mill that only makes fine dust isn’t broken — it’s set too tight. Coarseness lives in one place: the nut on top.

The fix in one move

Pepper coarseness is set by the gap between the spinning rotor and the fixed ring. Screwing the nut down closes that gap (fine); backing it off opens it (coarse). If everything comes out powder, the nut is too tight — loosen it anti-clockwise a half turn and test. The background is in how to adjust coarseness and how a grinder works.

Nut position	Gap	Grind
Tightened (clockwise)	Narrow	Fine powder
Middle	Medium	Table grind
Loosened (anti-clockwise)	Wide	Coarse crack

If it still grinds fine

• It won’t go coarse at all. Some budget mills have a shallow adjustment range, and a worn soft-steel burr can stop cutting cleanly — see when to replace.
• The nut won’t turn. Salt or grime may have seized the thread; the top-won’t-unscrew guide frees it.
• It’s every setting, not just fine. Then it isn’t adjustment — work through the troubleshooting guide.

Got the opposite problem? See pepper grinder too coarse. A mill with real range, like the Haomacro premium modern, covers fine dust to steak-crust from the one nut.

Frequently asked questions

How do I make my pepper grinder grind coarser? +

Turn the adjusting nut on top anti-clockwise (counter-clockwise) to widen the gap between the burrs. Loosen in half-turn steps and test until the crack is coarse enough.

Which way loosens a pepper grinder? +

Anti-clockwise loosens it for a coarser grind; clockwise tightens it for a finer one. The nut on the very top is the control.

Why is my grinder stuck on fine even when I loosen it? +

Either the adjustment range is shallow, the burr has worn, or the nut isn't actually moving because the thread is salt-seized. Check that the nut turns freely first.

Can every grinder do a coarse crack? +

Most adjustable mills can, but cheap ones with a limited range may not. A ceramic mill with a proper adjustment covers everything from powder to coarse.
