Getting a mix of fine powder and coarse chunks in the same grind? An uneven grind ruins extraction, and it usually points to worn burrs, buildup, or a setting that has drifted.

Why the Grind Is Uneven
- Worn or dull burrs that no longer cut cleanly.
- Buildup between the burrs skewing the gap.
- A loose or drifted setting.
- Blade grinders, which chop rather than grind evenly.

How to Fix an Uneven Grind
- Clean the burrs. Remove buildup that throws off the gap.
- Reset the setting. Confirm the grind adjustment is seated and consistent.
- Check burr wear. Inspect the burr edges for dullness or chips.
- Grind in short bursts. On blade grinders, pulse and shake for a more even result.
Pro Tip: Burrs are consumable. After a few hundred pounds of coffee they dull and grind unevenly no matter how clean they are, so worn burrs are worth replacing on a quality grinder.

Because grind quality ties to the burrs, it helps to check them, and reviewing a stuck burr, dull blades, or jammed beans can reveal the cause.
When to Call a Pro
If clean, correctly set burrs still grind unevenly, they are worn out. Replacement burrs restore consistency on grinders designed for it; otherwise replace the grinder.
