Rancilio Rocky Doserless Coffee Grinder review

If you are in the market for a top end consumer grade coffee grinder, take a good long look at the Rancilio Rocky Doserless Coffee Grinder. While a Mazzer Mini would be overkill and overpriced, but you may need something closer to commercial grade than a Solis Maestro, then the Rancilio Rocky hits the sweet spot. This is one of the premier grade coffee grinders and delivers consistent quality for espresso through drip and (almost) up to press pot. It is solid and relatively quiet while in use – and is a great option for grinding for each individual shot of espresso. It’s also highly compact, which means that you can squeeze it into a small kitchen full of equipment without any problems. The Rancilio Rocky also compliments the Rancilio Silva Espresso Machine well.
The highlights of the Rocky are its solidity and quality, its ease of adjustment, and in the case of this doserless model, its ability to grind for each dose of espresso or brew with minimal holdover of grounds. Because the path from burrs to chute is so short and unobstructed, you can rap the side when done and dislodge any leftover grounds, or simply remove the two screws holding in the chute to use a brush to clear it.

The metal hoop below is perfect for holding a Gaggia or Pavoni portafilter when grinding, and can be removed with one quick tug to allow you to grind into a filter, press pot, or bag. The Rocky’s weight keeps it steady – it is no flimsy lightweight – and furthermore the power switch and grind switch are separated on the doserless model, which is a nice added touch.

Having the grind switch on the front is convenient. Some specs to note:

  • 50mm commercial grade grinding burrs
  • Grinds directly into porta filter for simple operation
  • Powerful 166-watt direct drive quiet operation motor
  • Tinted hopper with a 0.65lb capacity
  • Simple variable grinder adjustment control.

There are some disadvantages with the Rancilio Rocky when compared with a Mazzer Mini. On the coarse end of the adjustment, the Rocky just does not quite make it to a real french press grind. Also, the grind adjustments are stepped, not stepless. (as compared to the Mazzer mini which is stepless) In an ideal situation, you would want a stepless coffee grinder to allow you grind in whatever consistency you wish.

That said, the steps are close enough that so it’s not really a problem in getting the grind that you desire, and the system of a release button on the collar that adjusts the burrs is slick and simple.

Another thing to note is that the Rancilio Rocky might stall while grinding, and requires a ‘push’ on the metal burr flanks to start grinding again.

You can read online about “Rocky Jams” or “Rocky stall” or other similar phrases which will show many references to this issue, which may be a matter of inconvenience. The Rancilio rocky also tends to get covered in coffee dust; which needs cleaning up after a day’s grind.

Overall, the Rancilio Rocky Doserless Coffee Grinder is beautifully designed and built like a tank. The consistency of the grind is good enough to make a huge difference in the flavour of the coffee, which emphasizes the subtleties of roast variations. While inspecting every grind we noted that every ground size are the same, which is really what you should be looking out for.

Do note that because this is a doserless model, you will need to provide some sort of container to put under the spout; a medium beaker or coffee cup would be about the right size. The Rancilio Rocky has more power and grinders large volumes fast; you can try removing the grinder’s finger guard from the bottom of the hopper to make this even better.
