Abstract: A coffee puck removal device (10) to remove a coffee puck (24) from a portafilter (20) is disclosed herein. The coffee puck removal device (10) has an open compartment (22) containing the coffee puck (24), the coffee puck (24) having an exposed major outer face (26) and a major inner face (28) when the coffee puck (24) is located in the open compartment (22). The device (10) includes: a body (12) having a rim (14) surrounding an aperture (16), with the rim (14) being configured to engage the portafilter (20), with the open compartment (22) facing the body (12) to inhibit air passing between the portafilter (20) and the rim (14); and a vacuum source (30) to remove air from the aperture (16) so that air pressure applied to the major inner face (28) is greater than air pressure applied to the exposed major outer face (26) so that the coffee puck (24) is removed from the portafilter (20).
