  3. Place your Chemex onto the scale Do not turn the scales on yet.
  4. Fold the paper filter in half and form a cone With smaller Chemex filters fold the smaller circle at the bottom.
  5. Put the paper filter into the Chemex
  6. Pour a little water into the filter paper to wet it Make sure all parts of the filter are wet.
  7. Discard the water once it has drained through the paper filter First, remove the filter, discard the water and replace it after. Make sure the Chemex keeps steady after.
  8. Add the coffee in to the paper filter Gently shake or tap the Chemex to level the ground coffee. Optionally: Make a small well in coffee grinds using a spoon or your knuckle.
  9. Turn on the scale, ensuring it reads `0g` Some scales will require to switch to "Grams" mode. Filtru-supported scales will need to be tare'd manually.
