Hi all,

Just bought my first grinder...a Mazzer Mini Electronic A.

Is there anything in need to do to "break it in" correctly? Or, is it good right out of the box?

Thank you in advance,

Steve

Oh, btw, I just bought a Alex Duetto II as well. Is there anything in need to do right out of the box as a break in? Or, is it just plug and pour? Thanks!

Your Alex will be "pretty much" plug and pour. You will need to find a temperature range that is right for the beans that you use. Typically with PID'd machines there is an offset between the temperature that is measured by the PID and the temperature at which the coffee is brewed - so your indicated temperature may be different from what you actually want to brew at by a few degrees. Other than that it is a matter of developing your skills to optimize technique for that machine.

Most grinders benefit by running some "throw away" beans through them to "run in" the burrs. It varies by grinders as to the appropriate amount. Perhaps a Mazzer user can comment here.

Observation suggests burrs do have a seasoning period. Since this coffee will not be getting consumed you can use 2 or 3 pounds of inexpensive lightly roasted coffee. I would avoid dark roasted oily beans as they will make a mess in the hopper and grind chamber. Fill the hopper up, grind a half pound then let the grinder rest for a half hour to cool. Run a couple pounds through it, clean it out, fill it with good beans and start using it.

With the M7D I ran a pound of throwaway beans through first, and I've had to tighten the grind noticeably since I set it up. Seems to be stable after 8lbs or so. I should have got more crap coffee to run through the K30 before I started using it. Getting some dosing inconsistency right now.
