Understanding Grind Size: The Key to Better Coffee
Master the Grind, Master the Flavor
Before water touches the grounds, the quality of your coffee is already decided—
because grind size determines extraction.
Understanding how fine or coarse your grounds should be will elevate every cup you make.
1. Fine Grind（细研磨）
Texture：like powdery sugar
Use for：Espresso
-
Slow extraction
-
Richer, heavier body
-
Too fine → bitterness increases
2. Medium Grind（中研磨）
Texture：like table salt
Use for：Drip coffee, Aeropress
-
Balanced acidity
-
Clear, smooth flavors
3. Coarse Grind（粗研磨）
Texture：like sea salt
Use for：French press, Cold brew
-
Light, refreshing body
-
Minimal bitterness
4. How to Know If Your Grind Is Right?
✔ Espresso runs too fast → grind finer
✔ Espresso tastes sharp or sour → grind finer
✔ Espresso tastes harsh or bitter → grind coarser
✔ Crema too thin → increase dose
Grind adjustment is the secret weapon behind professional-level coffee.
