Your brewed coffee tastes excessively bitter. This can be caused by the grinding level being too fine or the coffee type being unsuitable.
Click steps to track your progress.

Try changing the coffee variety to one known for a less bitter profile.
Adjust the brewing temperature if possible, as very hot water can extract more bitterness.
