How do you fine tune your grounds?

To fine-tune your coffee grounds, start by adjusting the grind size based on your brewing method; coarser for methods like French press and finer for espresso. Experiment with the brew time and water temperature, as both can significantly impact flavor extraction. Regularly taste your coffee and make incremental adjustments to find the balance that suits your preference. Additionally, ensure your equipment is clean and your beans are fresh for the best results.
