Oh, you saw that right–it's a Rancilio Rocky Grinder available in its exclusive black framing as an open box! One of the most recognizable names in the espresso world–Rancilio has designed this grinder with all the professional features that they've become known for, and taken it one step forward with a full suit of black over its doserless open box form. Featuring a 50mm burr set formed from the finest tempered steel, the Rocky grinder is designed to offer 55 different grind-level options at the press of a button, all without conducting additional heat during the process. As for its functionality, this open box Rocky comes in the doserless variety allowing users more manual control over the amount of grounds prepared at a time. Enjoy your morning coffee in style, with an open box Rancilio Rocky Doserless Grinder in sleek black!

  • 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 a half pound 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 espresso to drip to 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 device shuts it down to prevent damage to the motor or the grinding mechanisms.
    • Pros
      • Commercial-Grade Burr Grinder: The 50mm steel grinding plates are the same construction and quality as Rancilio's commercial grinders. Note that the Rocky is not made for a commercial setting, this open box grinder just built tough!
      • Perfect Capacity: Smaller than the big commercial grinders, this open-box machine still handles a little more than a half pound of beans at a time.
    • Cons
      • Too Much Machine?: This is a high quality, high output commercial style open box grinder. Make sure the features fit your home needs.
      • 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.
