For everyone who makes espresso coffee at home, Grindenstein solves the extremely messy problem of removing the used grinds from your espresso machine"s portafilter or group handle. Forget trying to wash oily grinds down the sink or having to put your hand inside a filthy garbage can -just turn your portafilter upside down over your Grindenstein, tap tap, and you"re done - you have an empty portafilter. Grindenstein has a patented unbreakable design and its compact height allows you to store it on your espresso machine"s drip tray when not in use so it doesn"t take up precious counter space. Easily cleaned in the top rack of the dishwasher, each Grindenstein also comes with a great booklet filled with ideas on how to recycle the collected coffee grinds into a fantastic organic fertilizer for your garden.
