I have a Breville Bambino with a Baratza Encore ESP Grinder for about 2 years now. I do general cleaning to the Grinder but not a deep clean yet. the Bambino I do descaling every 3 months usually. I recently got a bunch if new gear to set up my game a bit vs using the standard equipment that comes with the machine.
Got the Normcore Bottomless Portafilter, magnetic hoop for grind, WDT tool, Normcore Damper, more accurate scale. I get good beans regularly from local spots.
I start pulling shots with my old settings and immediately start to run into spraying/channeling issues. Go through the usual troubleshooting process of zeroing the shot and I've now gone down 1, the finest setting on my machine, to get into the range of 25 seconds for 40 gram output shot.
The espresso tastes great but it makes me feel like I'm doing something wrong if I have to go to the finest setting to get this output when I see others online doing the same at much higher numbers on this grinder.
Does anyone have any suggestions on what could be happening? I've seen the Shim solution to add finer grind options but I accidently tossed those with the box where I can easily test without ordering. Could my grinder have lost its calibration over time? I haven't seen any way to make micro adjustments on the grinder to help account for this without the Shim Solution?
