The Comandante C40 Hand Grinder utilizes German engineering and design to produce a grinder of the utmost quality. The upgraded engine frame allows for less grind retention, eliminates bean particle build up within the upper internals, and allows for an overall smoother work-flow. In order to craft the perfect cup of coffee, it is imperative that the grind setting begins at 0. This can be achieved by turning the dial until the burrs close, and can be checked by the handle sitting in a horizontal resting position. Please be advised, the ideal grind setting for most Intelligentsia single origins and blends begins at 14 clicks, and the optimal setting for our espresso begins at 7 clicks.
