Rancilio Rocky Doser V3 Espresso Coffee Grinder

Best precision flat burr grinder for home use and for those who demand the best. The Rancilio Rocky Doser has been a long time “gold” standard for espresso coffee grinders. This pairs nicely well with the Rancilio Silvia espresso machine! These grinders encompass the heavy motor that is found on the Rancilio MD40. The next step up from a Rancilio Rocky is therefore a commercial grade coffee grinder.


Grinding Adjustment

Stepped adjustments give you a wide range of grinding from fine to coarse. Easier to go back and forth between different grind settings.

Quiet operation

Generally not higher than 70dB(A). Rubber vibration-dampening feet help keep the grinder steady and reduce noise.

Tinted bean hopper & doser

The blue tint helps to avoid pre-mature deterioration of beans from light sources (such as sunlight).


All coffee grinds into this chamber and is then dosed out as you need. There is an opening that allows you to pour in any extra unused coffee grinds. This helps reduce coffee waste.

Portafilter Fork

For easy espresso machine filter handle placement & dosing. Sits very low to the base. Some portafilter designs can even rest on your counter for “hands-free” operation.

Instruction manual

Written in English, German, French, Spanish, Italian.

  1. Differences between V3 vs V2:
    • The Rocky V3 Grinder now has a removable plastic grind catch tray.
    • The Rocky V2 Grinder has the same stainless steel base as always. This is not removable.
    • The Rocky V3 has replaced the Rocky V2.
  2. Each Rancilio Rocky grinder is repackaged by 1st-line Equipment before shipping out to you.Unfortunately, the original internal cardboard packaging by Rancilio can not withstand the rigors of UPS/FedEx, and there were many damaged shipments due to the original packaging not being adequate enough.
  3. The doserless chute cannot be purchased separately to add to this model.
  4. This grinder was designed in Italy to use smaller and less oily beans. You can use large and/or oily beans with machine by removing the finger guard. However you might have issues with large and/or oily beans not feeding into the grinders properly or the machine making a mess.
  5. There is no kit available to convert the doser model to a doserless model or vice versa.
  6. 1st-line Equipment, LLC is an authorized Rancilio repair center and we handle the warranty repair for Our customers' Rancilio espresso machines! Our master technician alone has over 35 years in the coffee and espresso repair business! This is why so many customers choose 1st-line as their premier choice for Rancilio home products!
  7. With the doser, there is no way to fill each individual chamber evenly. Best recommendation is to grind only what you need and dose everything out.
  8. How to find the relative zero or "true" point on the Rancilio Rocky (doser or doserless).
    1. Make sure there are no beans in the hopper.
    2. While the grinder is powered on and running, briefly rotate the bean hopper to to the lowest numbered setting where metal-to-metal is heard.
    3. Immediately back off to a higher setting. The point of metal-to-metal screeching becomes your relative zero point. Note that this point may be higher or lower than the numerical zero point on Rancilio Rocky grinders.
  9. Upgrading the V3 plastic base and removable tray on a V2: You will need to order these 2 parts: 38-123-677 and 38-123-678. there are 3 screws on the bottom to remove for replacement.

  1. Changing grind settings: As with all coffee grinders, it is very important to only change grind settings when the unit is powered ‘on’ and the burrs are in motion. If you do not do this, the burrs will ‘gunk’ up and require cleaning by you every time this occurs. Changing the grind settings when the burrs are not in motion will render the grinder to only produce very coarse grinds or no grinds at all. If this result occurs, this will be considered operator error for lack of following directions, and not be classified as a defective grinder.
  2. Finding coffee grinds in a new grinder: We have confirmed that the manufacturer tests EVERY grinder with coffee beans before it leaves their facility, but they are not always able to get every trace of coffee out of the grinders after testing. As a result, you may find coffee beans or grinds inside your grinder, or there may be grinds in the packaging when you unwrap it.
  3. Static issues: There are static issues with all grinders, even the highest quality models. We firmly believe that the static comes from the coffee beans. If you are having static problems with your coffee grinder, trying using a different blend of beans.
  4. Replacing burrs: NEVER use a flat head screwdriver and hammer to wedge under the burrs for removal. This could badly damage your grinder.
  5. Electrical cord: Please note that the electrical cord is placed between the packaging (foam or cardboard) and the underside body of the grinder. During shipping, it is normal for a bend or insignificant blemish / slice to damage the cord.

Espresso Grinder Warning

  • CLEANING WARNING: We recommend using grinder cleaning agents. We do not recommend any removal of the burrs or burr carrier for cleaning as re-assembly can cause damage.
  • ELECTRICAL WARNING: To avoid electrical damage to this espresso grinder which is not considered a manufacturer's defect, please acquire and install a single-outlet surge suppressor rated at 1080 joules or higher. The lack of the recommended surge suppressor, the espresso grinder can be damaged at the power switch, the capacitor, the motor, or the wiring.

      I have a Rancilio Rocky that is having trouble. There is a loud rubbing sound, or perhaps grinding sound, from the motor area. I have removed the upper burr component, and turned it on. The sound is still happening. Is the motor replaceable? Is something smaller, for example, bearings, replaceable? thank you

      To avoid the risk of damage to the threads, we recommend a cleaner such as Urnex Grindz sold on our web site. We will have another product soon as well as a spray to clean the hopper from oil build up.
