ROK Coffee Grinder

Made possible by a dedicated community of crowd funders from Indiegogo, the ROK Coffee Grinder is a revolutionary manual grinder for all forms of coffee preparation. The grinder boasts durable die cast aluminum construction with engineering grade components for ergonomic operation and long lasting performance. Your coffee is ground by a set of 48mm hardened steel burrs with a double bearing drive shaft and a Acetal plastic gears. The grinder can also be adjusted between stepped and stepless grinding by fitting the adjustment wheel with a washer for infinite grind settings. Stepless grinders have an infinite number of grind settings allowing you to dial in your exact fineness for the perfect extraction parameters.

Unlike most manual grinders, beans are evenly ground with minimal effort. The non-slip ring located below the base ensures complete stability while the grinder takes only 62 revolutions (approximately 30 seconds) to prepare a double shot of espresso. This speed is comparable to a quality electric grinder while significantly quieter (75 decibels). Each ROK Coffee Grinder also ships with a metal cup/tamper that can be used to measure whole beans, catch ground coffee, and tamp the portafilter of the ROK Espresso Maker.
