Did you know that a dirty or poorly adjusted grinder can impact on the quality of the coffee you produce? Rancidity in the bean hopper or a bad grind setting, can quietly turn customers away from your venue because the quality of the coffee being served is affected. Understanding how to maintain and fine tune your coffee bean grinder can set your venue apart from the ordinary outlet that waits for the coffee rep to drop in three or four times a year. Regular cleaning, maintenance and adjusting the settings on your grinder will ensure that the beans are being ground fresh and for optimum consistency.
