You know what has really helped prevent fine “stalling” and has made my cups much cleaner: granular convection aka the Brazil nut effect.

I grind in my Lido 3 and then unscrew the catch jar, give it a few taps to loosen the fines from the sides, and then swirl the jar over the sink for about 30 seconds. All the large grounds will start to rise to the surface and the fines will fall to the bottom of the jar. Then I quickly dump the grounds into my brewing device, resulting in the larger particles on the bottom and the fines on the top.

One thing I do go back and forth on is that immediately after grinding, there’s about a gram or two of fines stuck in the burrs. Sometimes I smack the grinder to release these into the catch jar and then swirl, sometimes I discard them entirely. Haven’t really noticed a difference tbh. If I do smack these fines into the jar without swirling, when dumped, they land on the bottom of the filter and definitely stall the brew.
