How to use

Fill the bean hopper with the desired amount of roasted coffee beans, secure the lid and set the grind adjustment to the approximate starting point for your brewing method. Hold the grinder steady with one hand and rotate the crank with the other in a consistent motion until all beans are ground. Adjust the grind setting finer or coarser in small increments and test brew until the desired extraction and flavor balance are achieved. Disassemble the removable components for periodic cleaning to maintain performance.

Usage recommendations

Use freshly roasted whole beans and calibrate grind settings for each brew method. Clean removable parts regularly to prevent buildup and preserve uniform grinding. For espresso pre-adjustment, use the COMANDANTE to refine dose consistency before finishing with a powered grinder.
