A cup of coffee takes a relatively fixed amount of coffee grounds. But the amount of grounds per grind can be different, depending on the type of beans.
By calibrating the grind, your coffee machine comes out with the precise amount of grounds needed, making sure that each cup is served with consistent quality.

Re-calibrate your grind if:
1. you change to different beans; or
2. the components are worn over time, in which case the amount of grounds may be inconsistent.
