Extraction question ...

...  The other thing that came through louder and clearer than ever before is that the pressure you use for the tamp ultimately reflects the flow rate of the coffee.  Never before was the relationship of the fineness of the grind and the pressure of the tamp so clearly revealed to me as this exercise demonstrated.

Mission Accomplished!

Don't. Adjust. The Tamp. Pressure.

Only. Adjust. The. Grind.

Ok ... update.  Today I pulled another shot ... I tamped very lightly ... it poured well.  The next shot I pulled I tamped a bit firmer than normal and it was a little slow.  I made one more revolution to the coarser side for the next day's extraction.
...
Espresso pulling ... who said that this was not a fine art?
 

Whoa Nelly!


Keep the coffee volume, distribution, and tamp consistent from shot to shot. Too many variables ruin a shots!

Ok Shaun and Robert ... I think I get you now.  DO NOT ALTER THE TAMP PRESSURE!

Correct?

It's a teeter totter towards the same place.
