Descriptive grind labels like this are illustrative starting points, not precise measurements — the same label can mean different particle sizes on different grinders. See the grind size guide for how to dial this in on your own equipment.

Equipment

Common problems

  • Concentrate too weak
  • Concentrate too strong or harsh
  • Cloudy or gritty concentrate

Adjust steep time or ratio for strength; grind coarser and filter more thoroughly to reduce sediment.

Cleaning & maintenance

Discard grounds and rinse the steeping vessel and filter thoroughly.

Replace reusable mesh filters if they become clogged or torn.
