For everyone who makes espresso coffee at home, the Grindenstein solves the messy problem of removing the used grinds from the filter. Forget trying to wash oily grinds down the sink, instead just turn your filter upside down over the drum and tap twice, you are done. You can store on your drip tray when not in use. It has a shock aborbing design while the thick and durable rubber sleeve protects the handle, making it quiet to use. The collected coffee grinds make a fantastic fertilizer for the garden.
