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.
Here is why the grind turns uneven and how to fix it.
This article will teach you:
- What makes a grind uneven
- Why burrs wear
- What to check first
- When to replace parts
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.
What You’ll Need
- A brush and cleaning tablets
- Replacement burrs if needed
- Your owner’s manual
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.
When to Look a Little Deeper
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.

Wrapping Up
Uneven grind is usually burrs or buildup. Here’s the recap:
- Clean the burrs.
- Reset the grind setting.
- Inspect the burrs for wear.
- Pulse a blade grinder for evenness.
Clean and check the burrs first, and consistency returns. You’ve got this.
When the test points to the part, shop coffee maker parts for your model and confirm the fit with the full model number before ordering.
