I don't see any channeling in the puck but wouldn't the flow start later if going finer?

Do you have this same machine?

Where are you looking for channeling , with a naked pf as the extraction occurs or after the shot has done and looking at the puck after the OPV has hit. If the later , thus is telling you little about channeling ( IMHO )

  • Blue Bottle Hayes Valley - Roasted Sept. 11 and rested since Sept. 13
  • Blue Bottle sent a card recommending: Dose - 20g, boiler 201.5F, extraction 32s, yield 20-20.5g
first extraction results:
  • Dose (automatic) 23g
  • Extraction time 32s total, including 7 seconds pre-infusion at 60% pressure
  • Yield - 46.5g (I stopped the extraction sooner than blue bottle suggested because this yielded close to 60mls)
It's not the worst thing I've ever tasted, but i would not describe it as "good" either. For those who are familiar with the Breville I used a grind setting of 24.

Finer grind?

Can you post another video? Also can you describe how it tastes in more detail? What didn't you like?

I would actually coarsen it up slightly and try to get more yield out (from that dose). Also - be suspicious of shots that take much longer than 30 seconds. They're not automatically bad, just maybe could be better.
