If you can't remember the last time you changed your espresso grinder burrs then chances are they could be dull. When you grind coffee, your burrs are slowly dulling each and every time you turn on your espresso grinder. This goes for all your bulk grinders too, though their burrs tend to last a little longer. We suggest replacing your burrs every 6 months at the very least.
