Multiple-compartment coffee mill hopper for a coffee mill

A coffee mill hopper assembly, comprising:

• a hopper defining a plurality of compartments for storing coffee beans, and at least one outlet through which coffee beans may be released from the respective compartments of the hopper;
• a compartment selector, comprising a shaft interconnecting a control knob and a closure member, said shaft being rotatably mounted to the hopper such that a rotational position of the closure member is adjustable by rotating the shaft around its axis (L) through rotation of the control knob, and wherein the closure member is arranged to cooperate with the at least one outlet of the hopper to provide at least one outflow aperture that, depending on the rotational position of the closure member, selectively enables a release of coffee beans from at least one compartment;
• characterized in that the compartment selector further comprises a first toothed member that is rotationally locked to the shaft and a second toothed member that is rotationally locked to the hopper, at least one of said toothed members being movably arranged relative to the shaft and spring-biased to force the teeth of the toothed members towards each other in a meshing relationship.
