Bang grinds in stein
Grindenstein is a compact knock box that bangs out your coffee grounds.

Grindenstein is a compact coffee knock box that bangs out your coffee grinds. It’s super strong and sturdy, and even tucks away on the drip tray of your espresso machine for space-saving storage.

Small but mighty.
Specifically designed to be stored on the espresso machine’s drip tray (under the group head), Grindenstein’s unique height reduces clutter on the kitchen bench top and fits easily in the top rack of the dishwasher.

From the school of hard knocks.
Grindenstein’s patented shock-absorbing design and solid steel core make it truly impossible to break.

Quiet achiever.
Thick and durable rubber sleeve protects the group handle, absorbs the striking force and makes it quiet to use.

Daily grinds put to good use.
Every Grindenstein and Big Grindenstein comes with an information booklet filled with great ideas on how to recycle the collected coffee grinds as a fantastic natural fertilizer for the garden.
