If the coffee tastes too bitter, you may be over-extracting due to a too fine grind or too long brewing duration. If it tastes weak, you may need a coarser grind or a longer brewing duration.
Step 5: Fine-Tune Your Grind Size
The grind size of your coffee beans plays a significant role in flavor extraction. After tasting your test batch, you may need to adjust the grind size:
- For a bitter taste: Use a coarser grind.
- For a sour taste: Use a finer grind.
Investing in a quality burr grinder can help ensure consistency in your grind size, improving the overall quality of your coffee.
Step 6: Regular Maintenance and Recalibration
