The Rocky is the most durable coffee bean grinder available in its price range. It is extremely well made and we highly recommend it for home use and light commercial use. It is a dosing grinder, which makes it especially suited for use with an espresso machine. Although, it would have no problem grinding fine or coarse enough for any type of coffee/espresso machine you might have. The forks that are designed to hold your espresso machine portafilter in place are removable so that you may use any receptacle you want to catch the coffee. The Rocky is the grinder of choice for the finicky home barista due to its quality of grind and durability. Please note that most grinders are tested at the manufacturer and coffee grounds may be found in the grinder as a result. All machines sold are new unless otherwise clearly stated. Rancilio is in the process of updating the look of the Rocky Grinder, it may ship with either a rose tinted or blue tinted bean hopper and ground coffee container.


Features & Benefits: Coffee

Heavy Duty Construction

This stainless steel version has a stainless steel back panel and base with a heavy-duty black case aluminum frame. This commercial-quality construction is durable and designed to match your other Rancilio products.

Multiple Grind Settings

The Rocky can be quickly and accurately adjusted using its 55 different grind settings. To make the adjustment you just push down on a release lever and turn the bean hopper. You can quickly and easily change from course to fine. It can grind your beans into a fine powder for Turkish coffee or espresso and even course enough for French press. With a Rocky the most particular barista will be able to fine-tune their extractions to perfection.

Heavy Duty Motor

The Rocky’s motor is legendary. It is the same motor that Rancilio uses in the Commercial MD40 grinder. It is a 166-watt direct drive motor that is very quiet and extremely powerful. It will not slow down even under the most demanding workload. The motor alone weighs around 12 lbs. and spins at 1,725RPM. It has a high temperature overload switch to prevent possible damage if a stone gets caught in the burrs.

Top Quality Grinding burrs

Like the motor the grinding burrs on the Rocky are the same ones that Rancilio uses in the commercial MD40 grinder. They are the flat plate style and 50mm in diameter that are even designed to handle a commercial load.

Easy to use Controls

To turn the grinder on and off you just have to flip the switch that is located on the lower left front corner.

Tinted Hoppers

Both the bean hopper and ground coffee container are made of tinted plastic that are designed to help keep your coffee fresh. They both have covers that also help seal in the freshness. Both the bean hopper and the ground coffee container can hold up to 10.5 oz coffee.

Dosing Grinder

The Rocky is designed to dispense the ground coffee directly in to your espresso machine portafitler. After the coffee gets ground it drops in the ground coffee container. Then just pull the handle and it will dispense approximately 7 grams of coffee through a small hole in the front directly into your portafitler. You will notice the two plastic forks that are designed to hold your portafilter in place. These are removable so that you may place any receptacle that is less than 3 _” tall such as a filter for a drip coffee machine. To remove them you just have to remove two Phillips head screws. Just give us a call for details on to remove the forks.

LEE asked:

I have used my Gaggai grinder for 8 years.  For expresso I use the setting of 4.  I received my Rocky grinder today from WLL.  What is the suggested setting for espresso grind on dial. thanks Lee

Answer by Sanfam:

With the Rocky, the initial "dialing in" of the grind is largely down to trial and error.  I would suggest starting around "8", grinding and attempting a few shots, and adjusting downward one step at a time and repeating.  Once it's dialed in, you'll be set for this particular bean.  If "4" works for you right now, then "4" is just fine!
