MiiCoffee DF64 Single Dosing Coffee Grinder FAQ
What grinder burrs come supplied?
A: It comes with Italian made ItalMill 64mm flat burrs. It's made of standard hardened steel.
How low is the retention?
A: After one spin we swept out all the coffee grinds left behind from the top and bottom burrs and any areas that could cause an exchange of retained coffee. We then weighed this collected coffee. In the case of the sample it's weighed 0.5 of a gram.
How good is the grind consistency?
A: It's very good. We visually checked grinds using magnifying glass and they are pretty uniform. However the most important factor is taste. Using Rocket Espresso R58 with bottomless shots we have achieved SCA Gold Cup Standard results for Espresso with a refractometer tests.
How is the burr alignment?
A: The burr chamber and top burr unscrew and are removed together as one piece. They sit on a bed of three springs. The springs tolerances seem perfectly adequate and when the top adjustable collar is screwed down onto the top burr and chamber its locks into place tight and securely. The design is efficient and economical especially considering the value of the grinder.
