For the sake of making home espresso easier, I’ve designed the Grindtamp concept. It removes the need for the fiddly process between grinding beans, and tamping the grounds into the portafilter by combining the mill grinder and tamp into a single object.
Obviously inspired by the hario slim, which is a great mill grinder, but it’s annoying getting the grounds out of it and into the portafilter. The Grindtamp concept would help greatly. You would pull the tamp plunger out, grind beans into the container, upturn the container into your portafilter, and push the plunger back in to tamp the grounds.
The tamp size adjustment, which you can see screwed onto the top of the ground container, could come in different sizes to account for the various portafilter sizes.
