Woke up at 6:00 a.m. itching to tackle the grinder distribution issue. So, let's move straight to some closeup views.Out of the chute
As the burrs spin, they disperse the grounds in a spiral pattern, like a small tornado out of the chute. That can clearly be seen in the picture above. Notice how fine and even the grounds look when they come out, and how evenly they are dispersed. It is like grains of salt. Settling
As the grounds settle, one can clearly see the mound's spiral character. Notice the crater at the top, and the spiral galaxy imprint in the background. This is very different from the Mazzer Mini with a doser. There, the grounds are tunneled through a 1" wide chute on their way to the doser. Versalab Grounds - Closeup
There are practically no clumps in the image above.

There are huge rocks coming out of the Mazzer. The contrast with the M3 smooth and even grounds mound is startling.The Preferred Barista Technique With the M3
As I was concerned with the crater in the middle of the mound, I tested three Barista leveling and distribution techniques. First
: Stockfleth. This is a circular sweep of the basket using the index finger. I did it clockwise to be in sync with the grinder's spiral dispersion direction. Result: No channeling, though it took longer than usual for the puck to saturate its center. That resulted in somewhat slightly uneven extraction.Second:
Schomer. A sweep across the basket rim in four directions NSEW. No channeling, but still, the center takes longer to saturate than usual.Third:
No distribution at all, just leveling the puck in one sweep across the rim. Bingo! Even saturation across the puck and no channeling. The resulting shot was fantastic.Out of the grinderMy preferred method at this point - just one sweep to level the puckThe result in the cup
Wow! What do you do when your grinder tells you "step aside espresso boy, and don't mess with me". Andy and Jim were right. One can get very lazy and sloppy with this wonder of a machine.
However, I do not intend to role over and die. In the coming days I will try to see if there is a distribution technique that will do even better.
