Cleaning and maintaining a coffee grinder – this is how it’s done


For the best coffee experience, we recommend that you don’t save on the grinder. To enjoy your coffee grinder (or espresso grinder) for a long time, take good care of it. Here you will find our tips for cleaning and care.

Roasted coffee contains fats and oils. The longer and hotter espresso is roasted, the lower the water percentage and the oilier (or shinier) the coffee beans are. Over time, these oils form a fine film on the surfaces inside the grinder with which they come into contact. There they oxidise and become rancid. Coffee, whether raw or roasted, absorbs environmental aromas very quickly. Therefore, fresh coffee beans that pass through a grinder that has not been cleaned for a long time will take on a slightly rancid aroma. Bean residues also reduce the performance of a coffee grinder: the grind becomes less consistent and the lifetime of the grinder decreases.

Our tips for cleaning your coffee grinder

  • The oilier the coffee you use, the stronger the sedimentation effect. Say: If you use very dark roasted beans to make coffee, make sure to clean your grinder more often – we recommend once a week.
  • It is a common misconception that you can clean a coffee grinder by grinding rice grains. Rice does have the ability to bind oils, but the rice grains are too hard and can damage disc and cone grinders. Ceramic grinders may even break off pieces of ceramic.
  • The most effective method is cleaning with special „cleaning beans“. We also offer coffee grinder cleaner. It consists of white-yellowish, edible granules that are slightly reminiscent of coffee beans in shape. Simply put the cleaning beans into the grinder like coffee beans and grind them through. This binds coffee oils and residues and cleans the grinding discs well. The cleaning beans are both odourless and tasteless. Therefore, they do not affect the taste of your coffee. Regular use of the cleaning agent guarantees a neutral coffee taste and considerably prolongs the life of your coffee grinder.
  • Important! If the grinder no longer functions due to clogging, or if the grinder is no longer intact due to lack of cleaning, warranty liability is excluded.

Tip: For espresso grinders, occasionally vacuum the grinding discs with a hoover – remove the bean hopper first.
