Sometimes a bad cup of coffee isn’t about the beans—it’s about the process. Using too hot or too cold water, grinding beans too fine or too coarse, or skipping the right ratio can all affect flavor. Even forgetting to clean your brewing tools regularly can leave a bitter taste. The good news is, these mistakes are easy to fix. By adjusting grind size, keeping your equipment clean, and balancing water temperature, you can bring out the natural sweetness and aroma in every cup.
