Grindenstein Knock Box is a dump bin for coffee grounds. It completes a home espresso machine and is about the size of a big mug – holding a substantial 520ml (6-8 coffee pucks). It also fits into the hand for easy emptying.
Did we mention that Grindenstein is a good looker ? It’s also dishwasher safe, very durable, and has a non-slip base. The dump bar may be covered with santoprene, but inside is a solid steel core.
Grindenstein was created by young Australian Alex Gransbury when he was a student. He began selling it at weekend markets in Canberra. It’s now sold in Italy, Norway, the USA … worldwide.
And the name ? The original Grindenstein prototype was made from a lump of pipe, garden hose, and an oversized nut and bolt. Mr Gransbury reckoned it looke like the head of Frankenstein. Frankenstein + Grinds = Grindenstein.
