New grinder? Looks like someone used oats to clean it

So you put coke in your grounds and then proceeded to show us under the veil of a question?
Very good. Very good. Enjoy

It could just be the silverskin that covers the coffeebeans or residual silverskin that was lodged in the grinder from a previous set of beans. How do your beans look?

Snort it and find out 👀

If it’s more tan colour it’s coffee chaff (coffee skin that still stuck to bean inside on light roast). If it’s pure white it could be something like coffee grind cleaner (like Grindz or similar).

Just to cover all the (oddball) options, is it possible that something fell into the grinder before/during the grinding process?

Please FWD to circlejerk and report about the bricks of cocaine packaging in the coffee not being sealed properly.

Try to buy some cheapo super dark roast beans and grind them. If after several time you still see those white stuff, then it’s not the silverskin of the bean.

After looking at the surrounding in your picture I can almost certainly say that it’s dust. 😂

Sorry, I snuck in and itched my head so some of my dandruff got in there.

Change your coffee beans to a different supplier, grind 5-10 seconds from those, throw it away, grind 5-10 seconds and check. If you get the same thing, I suspect you had a small stone in a previous batch of coffee beans that either chewed from your grinder ceramic stones or broke them. If this is the case i would not buy coffee again from the last suppliers.

If it’s consistent then the burrs have probably become misaligned or blunt. I usually start seeing more chaff in my commercial grinder when the burrs need replacement soon.
Or you’re not grinding fine enough. New grinder owners tend to have a hard time finding the zero point with stepless grinders.
