A coffee grinder suitable for home use can include a housing that receives coffee beans, a grinding component within the housing, a removable container that receives coffee grounds dispensed from the grinding component, and a base located beneath the grinding component that supports the container. Magnetic components in the base and removable container can optimally align the container when placed atop the base. A knocker system can dislodge ground coffee residue into the container when actuated. An intelligent drive system can utilize feedback to drive the grinding component at a constant speed to minimize coffee grounds size variances. A grinds chamber in the housing can define an asymmetrical cross-sectional geometry. An augur that drives the grinding component can have an outer thread that forces coffee beans through the grinds chamber, and a grinds chamber housing can include a protective shoulder that covers a lead-in portion of the outer thread.

A unit of a coffee apparatus, in particular a coffee machine for brewing a coffee drink, includes a coffee bean container for storing the coffee beans, a portioner for portioning the coffee beans for an individual portion, and a grinder for grinding the portioned coffee beans. The coffee bean container and the portioner are formed in a common container module. The unit has a module receptacle, by which the container module can be connected during use and removed after use, and the container module has settings for a portion amount and a degree of grinding, which can be selected by the user. The portion amount setting influences the portioner and the degree of grinding setting influences the grinder. A simple, cost-effective and easy-to-use information exchange module between coffee container and coffee apparatus is thereby created.

An apparatus for dosing coffee beans for the purpose of selecting a metered quantity to be ground comprises a portioning device with a metering chamber having a receiving volume for receiving the coffee beans. The receiving volume is variable. Preferably, the setting of the metered quantity is performed mechanically, wherein the effect of the settings on the portioning device takes place mechanically. Preferably, the apparatus comprises a setting ring for manually adjustment of the metered quantity
