Random gusher/choked pour diagnosis
Just recently, with the same grind/dose/tamp using the same batch of beans, I have randomly been experiencing occasional gushers and also choked pours.
Maybe 1 in 15-20 shots.
I am fairly confident it is machine/grinder related and not a usage issue.
My guess at potential problems are:
1) Pump on the way out (doesn't sound any different)
2) Worn grinder burrs
3) OPV playing up
Before I start replacing parts I thought I would check if any of these are more likely or if it could be something else.
I have an Iberital De Recanvis which has ground about 400g per week over the last 7 years for me.
However I bought it from a Coffee Snob and don't have any information about its previous history.
Quaha single boiler, likewise I've had for 7 years but don't know the history of.
Sounds like it's probably down to worn out burrs on your grinder mate...
Most likely generating random quantities of fines along with correctly sized cuttings.
A new set of burrs shouldn't be too expensive and may get you back into coffee nirvana territory...
Certainly can't hurt...
No, not too expensive.
Just wanted to check it was a likely source of the problem before purchasing.
