Hey guys,
I decided to try some Ethiopian that was roasted fairy light through the 'spro machine and got mixed results. This was roasted for syphon or plunger use and I don't like the outcome of it through the 'spro.
I get a nice coloured extraction and it is pouring well; the problem lies in that when using a naked porter filter, I get some fly away high pressured pin sized leaks. I know my tamping is good, as I get great results with every other blend/origin I use.
I'm using a machine with group head boilers, at a fairly high altitude. I have the temp set at 89C which extracts at around 92C and am using a synesso two shot basket.
I am trying to establish whether it is due to the roast profile, the light roast, the type of bean or all of the above.
I have roasted some more of it darker to see if I get the same result and the start the elimination process, but it will be a day or three before I attempt to use it.
what are your thoughts on this?
Dave
