How to Choose the Right Grind Size for Your Coffee Maker

Choosing the correct grind size for your coffee is just as important as the beans you buy. The grind determines how water extracts flavor from coffee grounds, directly affecting taste, aroma, and strength. Whether you brew with a French press, espresso machine, or pour-over, using the right grind size ensures your cup tastes exactly how it should.

1. Why Grind Size Matters

When coffee grounds are too fine, your brew may taste bitter and over-extracted. If they’re too coarse, the coffee can be weak and under-extracted. The right grind size balances water contact with coffee, unlocking the perfect flavor.
