Coffee mill hopper assembly (1), comprising a hopper (10) with multiple compartments (18a, 18b) for storing coffee beans and at least one outlet (22) through which coffee beans may be released from the respective compartments, and a compartment selector (30) comprising a rotatable control knob for adjusting the position of a closure member (36) that cooperates with the at least one outlet (22) to provide for at least one outflow aperture that, depending on the rotational position of the closure member, selectively enables a release of coffee beans. The compartment selector (30) further comprises two toothed members that are rotationally locked to the control knob (34) and the hopper (10), respectively, wherein at least one of said toothed members (50a, 50b) is movably arranged and spring-biased to force the teeth (54a, 54b) of the toothed members towards each other in a meshing relationship.

1. 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. 2. The coffee mill hopper assembly according to claim 1, wherein at least one of the first and second toothed members comprises a plurality of teeth that are substantially identical and equidistantly spaced apart in a circumferential direction around the axis (L) of the shaft. 3. The coffee mill hopper assembly according to claim 1, wherein one of said toothed members has 2n teeth, n being the number of compartments, while the other of said toothed members has a number of teeth that is equal to or less than 2n. 4. The coffee mill hopper assembly according to claim 1, wherein the two toothed members define at least three meshing positions, wherein: in a first meshing position, the closure member cooperates with the at least one outlet of the hopper to provide at least one outflow aperture that enables a release of coffee beans exclusively from a first of said compartments;in a second meshing position, the closure member cooperates with the at least one outlet of the hopper to provide at least one outflow aperture that enables a release of coffee beans exclusively from a second of said compartments; andin a third meshing position, the closure member cooperates with the at least one outlet of the hopper to provide at least one outflow aperture that enables a concurrent release of coffee beans from both the first and the second of said compartments. 5. The coffee mill hopper assembly according to claim 1, wherein said at least one movably arranged toothed member is movably arranged in a radial direction relative to the axis (L) of the shaft. 6. The coffee mill hopper assembly according to claim 1, wherein said at least one movably arranged toothed member is movably arranged in a direction parallel to the axis (L) of the shaft. 7. The coffee mill hopper assembly according to claim 1, wherein the first toothed member is fixedly attached to the shaft. 8. The coffee mill hopper assembly according to claim 6, wherein the second toothed member includes an annular base member that is coaxially arranged with the shaft, and movable along the axial direction (L) thereof. 9. The coffee mill hopper assembly according to claim 1, wherein the compartment selector includes a coil spring that is arranged coaxially with the shaft, and that urges the second toothed member towards the first toothed member. 10. The coffee mill hopper assembly according to claim 1, wherein the plurality of compartments share a common outlet, and wherein the closure member is arranged to cooperate with the common outlet. 11. A coffee mill, comprising: a coffee mill hopper assembly according to claim 1; anda grinder operably connected to the coffee mill hopper assembly, and configured to grind coffee beans released from the hopper through the at least one outlet thereof. 12. A coffee machine, comprising: a coffee mill according to claim 11; anda brewing receptacle for receiving ground coffee beans output via the grinder.
