The Grindenstein is a compact knock box that removes coffee grounds. It is specially designed to be stored in the drip tray of the espresso machine (under the group head), while its unique height reduces clutter on the kitchen surface and it easily fits on the top rack of the dishwasher.

The patented shock-absorbing design and sturdy metal core of the Grindenstein make it gentle and durable. The thick rubber protects the group handle, absorbs the force of knocks, and enables quiet use.

Each Grindenstein and Big Grindenstein comes with an informative leaflet featuring great ideas on how to reuse the collected coffee grounds as a fantastic natural fertilizer for your garden.
