Hi Jackstar,
Unfortunately it's not feasible for me to swap grinders with my friend temporarily.
An update for those interested.
I was determined to understand what's going on and started keeping a log of my extractions from 11/2.
I used the same technique each time, same dose, same boiler temperature, and persevered with the same grind settings until I was able to pull several consistent shots.
Some observations:
- after some initial variances I seemed to reach a level were my extractions were very consistent - after I changed beans and dialled in the grind, the inconsistencies returned.
- ambient temperature and humidity does not seem to significantly affect extraction.
- despite paying particular attention to how I handle the grinds and using a distribution tool, i consistently get channelling and spritzing.
I feel I have hit a level of consistency now with the occasional outlier which I can't explain.
I've not put around 1kg through the new burrs...
Perhaps my new burrs are starting to wear in.. but in any case I'm much happier than I was a week ago.
