If you like to rise and shine every day with a cup of coffee, and have your beans ground quickly, efficiently with just the right proportion of fineness, then Rancilio HSD-ROC-SD Rocky Grinder is an ideal addition to your home coffee making setup.

Rancilio is the most commendable brand in my whole family. This Italian-made stylish grinder with solid construction and remarkable performance offers you all the control you need for a perfect grind. It uses high-end coffee-grinding technology and hence, preserves the maximum aroma giving you the original taste of the coffee beans. Its price is fairly reasonable for the excellent features and optimal functioning.

Features & Functionality Of Rancilio HSD-ROC-SD Rocky Grinder

Rancilio is one of the most popular brands in commercial quality coffee making machines and grinders. The SD model reviewed today is a doserless version of the Rancilio Rocky burr grinder. Let’s have a look at other significant features of this wonderful machine.

Design and Construction

The overall design of this electric burr grinder is  sleek, elegant and heavy duty. From a construction perspective, I found this model quite sturdy and easy to assemble, manage and operate. The back is made of stainless steel while the front is made from black metal, enhancing its durability.

The 50mm flat stainless steel burrs of commercial grade, with a powerful motor of 166-watts direct drive (spins at 1,725 RPM), generate less friction and prevent heat build-up while grinding. This means it will not burn your beans even when grinding for a long time.

Dimensions & Weight

This doserless grinder weighs 15.4 pounds with the dimensions of 9.8 x 4.7 x 13.8 inches. You can easily place it anywhere in your home, office or shop counter. However, I wouldn’t recommend it for small kitchens.

Multiple Grind Settings

Rancilio HSD-ROC-SD Rocky Grinder offers 55 ways to grind without producing extra heat during the process.

Bean Hopper Capacity

The grinder comes with a compact bean hopper. This blue tinted hopper gives your beans UV protection. It can easily hold up to a half pound (8 oz.) of beans, and lifts off for stress-free and easy cleaning.

  • Some coffee grinds may get left behind in the hopper and chamber. This is very common in almost all types of grinders (economical and expensive), and isn’t anything to worry about.
  • While grinding, you may not be able to change the grind adjustment to finer or coarser settings. It’s pretty difficult. So, always set the preferred grind in the first place, or you may need a second hand to help you with it.

Tips To Consider While Using Rancilio HSD-ROC-SD Rocky Grinder

  • If it shoots too slow, say more than 20 seconds, you will get an extremely fine grind. Adjust it to a bigger grind number on the dial.
  • If it shots too fast (less than 18 seconds) then your grind will be too coarse. This means you need to adjust the grind to a smaller number.

This best quality grinder with premium features and excellent performance is a remarkable choice both for private and commercial use.
