The benchmark grind. If coffee tastes sour and watery, grind finer; if harsh and dry, grind coarser.
☕ The Flavor Compass: Is Your Coffee Under-Extracted or Over-Extracted?
Sour, Salty & Watery? (Under-Extracted)
Water rushed through the coffee bed too fast without dissolving natural sugars. Solution: Grind finer or extend brew contact time.
Harsh, Dry & Astringent? (Over-Extracted)
Water lingered too long, pulling bitter wood tannins and plant fibers into the cup. Solution: Grind coarser or brew with slightly cooler water.
