Hi all. Iím settling in to ownership of my Bezzera BZ10 and Sette 270W and am happy to be in the ballpark. Iím yielding a solid 2:1 shot that most of the time tastes great. The rest is ok, but could be better.
I recently bought a naked PF to help with the diagnosis, which has confirmed what I thought was happening. Iím consistently getting a doughnut extraction like in the video. Looking at the puck afterwards, there are pinholes at the side to indicate channeling.
Iíve played with grind amounts and have settled on 17.5g in the standard 16g Bezzera basket. Any less and itís sloppy, plus I have a hard time levelling it as it sits below the surface of the basket. Any more and itís on the screen.
Iím starting to think my tamp is too small for my basket - 58mm tamp for a 58.94mm basket.
Before I go and spend more money, Iíd love to hear some advice on which way to tackle this. Work on my tamp to try get the edges compacted better? Get a new tamp? Buy a new basket? My tamp is a Clean Machine, flat bottom with square edges, 58mm tamp. Any tips?
