All of a sudden, and without any warning, my Elizabeth and my Niche have decide to rebel against me. The Elizabeth is pulling the shots way too fast (i.e. 18g in 14″). At first I obviously thought it was the Niche, so I calibrated the burrs again and set it a bit finer this time–same result. For those of you who own a Zero my setting is right now at a 9, which I think is very fine after one month of grinding a Colombian medium roast at 13.
I have an 18g VST precission basket, a Lelit naked portafilter, I do my group cleaning regularly and both preset buttons set to Dave’s settings. I tried both with bloom phase and boiler off as well as the 10″ preinfusion boiler on.
How can this be if I haven’t touched a thing ???
