Over-extraction

Very fine grounds or long brewing times can contribute to an overly bitter cup.

Very hot water can change extraction. Experiment with your brewing temperature.

Bean freshness

Old or poorly stored coffee may have less pleasant flavours.

Make small adjustments

Try a slightly coarser grind or shorter brewing time and compare the result.
