Pro tip: my 43rd bag of the year was the one that finally made me check my burr
I counted 43 bags since January before I noticed all my shots were pulling 4 seconds fast, and it turned out my grinder burrs had gone dull without me catching it. Check your burr date if your shots suddenly run quick, has anyone else had a burr die quietly on them like this?
Did you see that post about burr life going down faster if you grind light roasts? That could explain why yours died so quiet, those beans are way harder on the burrs.
