Then you open the Grindz container and pour 35 grams into the hopper – small, yellowish tablets in the shape of coffee beans. You start the grinding process. The tablets are crushed, you hear a different grinding sound than with beans, shorter and denser. Yellow particles, looking like ground cracker powder, trickle out of the spout. You repeat with a few beans to flush – the first ones still come out yellowish, the second ones clean dark brown. Done. Burrs and grinding chamber are free of coffee oils.\u003c\/p\u003e\n\n\u003cp\u003eThat's Grindz. Developed in June 2005 by Urnex in collaboration with Mahlkönig in Hamburg – and at the time, the world's first grinder cleaner ever. Pressed from grains, cereals, and pharmaceutical binders into coffee bean shapes. All-natural, food-safe, gluten-free (according to Urnex tests based on Codex Alimentarius standard), taste-neutral. A 430-gram container is sufficient for about 12 to 15 cleanings in a typical home espresso grinder. Made in the USA. We at Coffee Coaching Club are the exclusive Swiss importer for Urnex.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Grindz resolves\u003c\/h3\u003e\n\n\u003cp\u003eDuring grinding, tiny amounts of coffee oil adhere to the grinding burrs and the inner wall of the grinding chamber. Over weeks and months, these oils become rancid – and rancid oils mix with each new grinding cycle. The result: a stale aftertaste in freshly ground coffee, even if the bean itself is freshly roasted.\u003c\/p\u003e\n\n\u003cp\u003eGrindz works physically and chemically at the same time. During grinding, the tablets are crushed and penetrate into the same crevices and grooves where coffee oils have settled. The porous cereals absorb oils like a dry sponge. At the same time, they work mechanically – they gently abrade coffee residues from burr surfaces.\u003c\/p\u003e\n\n\u003ch3\u003eWhat makes Grindz special\u003c\/h3\u003e\n\n\u003ch4\u003e\u003cstrong\u003eNo disassembly required\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eGrindz works without the need to open the grinder.
