In a multi chopper, food is chopped and not ground. Theoretically, however, the MZ 400 or MZ 500 multi grinder can also be used to grind coffee beans, at least to a degree of fineness that is suitable for filter coffee machines or French presses. However, the amount of coffee beans that would have to be filled in for this is very high. We therefore recommend our ROMMELSBACHER coffee grinders for grinding coffee beans.
