Product Description

Rancilio. It's the most recognized name in commercial-quality espresso machines and grinders. The Rocky Doserless Coffee Grinder is ideal for the coffee enthusiast looking to step up from the basic grocery-store grind and commit to having better control over grinding. Featuring 55mm burr grinding plates crafted of the finest tempered steel, the Rocky is designed to deliver 55 different types of quality grounds at the press of a button, all without imparting additional heat during the process. Rocky's large, UV-resistant bean hopper holds more than a half a pound of beans so you won't have to stop mid-grind during a large dinner party for a refill.

This is an Open Box Product.

Features & Functionality of the Rancilio Rocky Doserless Grinder

  • Commercial Quality Grinding Burrs: The tempered steel grinding plates rotate at super slow speeds to prevent heat build-up, which can ruin your perfectly roasted beans. The hugely productive motor is also insulated to prevent overheating.
  • Excellent Home Hopper: The compact hopper is blue-tinted for UV protection of your beans, but still easily see-through for monitoring of your bean level. The hopper holds over .5lbs of beans, and lifts off for easy cleaning.
  • 55 Ways to Grind: A twist of the grind dial on the Rocky gives you 55 levels of control over the output of the grinder. The ultra-fine threading allows you the versatility of going from drip to Turkish or French press coffee brewing, and every other type between!
  • Quiet, Powerful and Safe: Rancilio designs for commercial use, and that means creating motors and grinders that emit as little noise as possible. The Rocky Grinder is no exception, and is one of the quietest available. Safety is just as important, with the balance of the grinding elements designed to prevent rocking and torque. Should the grinding mechanism jam or become overheated, a thermal protection devise shuts it down to prevent damage to the motor or the grinding mechanisms.
  • Commercial-Grade Burr Grinder - The 50mm steel grinding plates are the same construction and quality as Rancilio's other commercial grinders.
  • Perfect Capacity - Smaller than the big commercial grinders, this machine still handles a little more than a half-pound of beans at a time.
  • Price - Though it's much less expensive than Rancilio's larger machines, this grinder is still pricey.
  • Power Switch - Some users have complained about the placement of the power switch on the Rocky. Its location may make it difficult to handle the portafilter and operate the machine at the same time.
  • Large - The Rocky weighs 18 pounds and the motor makes up 11 of them. This will certainly take center stage in a small kitchen so make sure to measure your space prior to purchasing.

Two Questions. 1. When will this be back in stock. 2. I'm wanting a grinder for two things A Technivorm Drip and for an espresso machine. I keep looking at this vs. the Rocky grinder. Worried about static and inconsistency from the rocky. Would this go course enough for drip and could I easily go between the two settings on a weekly basis?

Best Answer: 1) We don't expect the Mazzer Mini in for another month or so. Be sure to click the link to "sign up to get notified when this item is back in stock" to receive an e-mail when it comes back in stock. 2) The Mazzer grinders are not good grinders for drip and espresso as they are stepless and therefore do not have specific steps/markings for the various grind settings. For this reason, once the grinder is dialed in to espresso, you will have a very difficult time dialing it back to the setting you found best for espresso. The other downside is that this grinder is calibrated to espresso and will not get as coarse as is necessary for applications such as drip coffee. It would be better to choose a stepped grinder, like those from Baratza or the Rancilio Rocky if you want to use one grinder for both applications, or to choose a lower priced grinder for your coarser drip style grinding.

The coffee grind has turned out to be better and more consistent than any other grinder I have used in the past. Great product. (Posted on 2/28/2013)
