How to set up and clean a coffee grinder

If you have a manual coffee grinder, the correct grind size setting is absolutely crucial for the result in the cup. Before you start, it’s always a good idea to read the manual for your specific grinder, as each type may have a slightly different design and setting mechanism.

Setting the grind size

  1. Unscrew the container for the ground coffee (bottom part of the grinder).

  2. Attach the handle (manual crank) to the top of the grinder.

  3. At the bottom of the grinder, you’ll find the adjustment nut (or wheel) used to control the grind size.

Most quality manual grinders use so-called “clicks” – small fixed steps that you can both hear and feel when turning the adjustment nut. One click = one defined adjustment.

How to find the first click

  1. Tighten the grind adjustment nut as much as possible until the burrs no longer spin freely (hold the crank so it doesn’t turn).

  2. Then begin to loosen the nut toward coarser grinding until you hear the first click.

  3. Make 2–3 clicks and try turning the crank as if grinding. If you hear the burrs scraping, add one more click.

  4. Repeat until the burrs no longer touch – that’s your first click (your starting point for setting).

Now check your grinder’s manual – most manufacturers list recommended settings for different brewing methods (espresso, moka pot, V60, French press, etc.) by number of clicks from the first.

For example:

Cleaning and maintenance

To preserve both coffee flavor and grinder longevity, it’s important to clean it regularly.

  • Never rinse the burr assembly with water! Water can damage metal parts or bearings.

  • Carefully disassemble the grinder and empty out leftover coffee.

  • Use the included brush or a soft brush to clean between the burrs and the hopper of any coffee residue.

  • You can usually rinse the bottom container (for ground coffee) with water, but always dry it thoroughly.

A well-maintained grinder will serve you for years – and the coffee will taste better than ever.
