Why Grind Size Matters

Why Grind Size Matters in Coffee

The Small Detail That Changes Everything

Grind size can make or break your brew.
Too fine or too coarse—and your coffee tastes off.
Here’s why grind size matters and how to get it right.


1. What Is Grind Size?

It’s how fine or coarse the coffee is ground after roasting.
Think powder vs. sea salt.
Each brewing method needs a specific grind size to extract the right flavor.


2. How It Affects Flavor

Grind size controls extraction—how much flavor is pulled from the beans.

  • Too fine = over-extraction → bitter, dry, harsh

  • Too coarse = under-extraction → sour, weak, flat

Balanced grind = balanced flavor. Simple.


3. Best Grind Size for Each Brew Method

Brew Method Grind Size Texture
Espresso Fine Like table salt
Moka Pot Fine-medium Between salt & sugar
AeroPress Medium-fine Slightly gritty
Pour-over Medium Like sand
Drip machine Medium-coarse Coarse sand
French press Coarse Like sea salt
Cold brew Extra coarse Rock salt

Wrong grind = wrong taste. Match it to your method.


4. Why Fresh Grinding Matters

Always grind just before brewing.
Pre-ground coffee loses flavor fast.
Oxygen, moisture, and time kill freshness.

Using a burr grinder (not blade) gives consistent results.
That means better extraction and better coffee.


5. Quick Fixes

Coffee tastes bitter? → Try a coarser grind.
Coffee tastes sour or weak? → Try a finer grind.
Start small. Adjust. Taste. Repeat.
