Why Grind Size Matters
The right grind size can be the difference between a bold, balanced coffee and a bitter or weak cup. Coffee grind size affects how fast water flows through the grounds, which impacts extraction time and flavour. A grind that’s too fine for your method can cause over-extraction (bitter, harsh flavours), while a grind that’s too coarse leads to under-extraction (weak, sour coffee).
If you want to get the most out of your Elixir Coffee beans, knowing the right grind size for your brewing method is essential.
Understanding Coffee Grind Sizes
There are six main grind sizes, each suited for different brewing techniques:
- Extra Coarse – Like rock salt (best for cold brew)
- Coarse – Similar to sea salt (best for French press, percolators)
- Medium-Coarse – Like sand (ideal for Chemex, batch brewers)
- Medium – Similar to table salt (perfect for AeroPress, pour-over, drip coffee machines)
- Fine – Like caster sugar (suited for espresso, Moka pots)
- Extra Fine – Powdery, like flour (used for Turkish coffee)
Choosing the right grind ensures proper extraction, optimal flavour, and a well-balanced cup of coffee.
The Best Grind for Each Brewing Method
Cold Brew & French Press (Extra Coarse & Coarse)
- Cold Brew: Use a coarse grind. This allows for a long steeping time (12-24 hours) without extracting too much bitterness.
- French Press/Plunger: A coarse grind (similar to sea salt) ensures a clean, full-bodied coffee. Too fine, and you’ll get a gritty, over-extracted brew.
Chemex & Pour-Over (Medium-Coarse to Medium)
- Chemex: A medium-coarse grind (like sand) ensures a balanced extraction, allowing water to flow steadily through the thick Chemex filter.
- Pour-Over: A medium grind (table salt texture) delivers a clean, bright cup. Adjus

t grind size slightly based on brew time.
AeroPress & Drip Coffee Machines (Medium to Medium-Fine)
- AeroPress: Depending on your brew style, a fine grind (between table salt and caster sugar) works best.
- Drip Coffee Machines: Use a medium grind, like table salt, to avoid over or under-extraction.
Espresso & Moka Pot (Fine)
- Espresso: A fine grind (like caster sugar) ensures proper pressure and extraction. Too coarse, and the coffee will be weak; too fine, and it can clog your machine.
- Moka Pot: A fine grind is also best, but slightly coarser than espresso to prevent over-extraction and bitterness.
Turkish Coffee (Extra Fine)
- This method requires an extra fine grind, similar to flour. The coffee is boiled rather than filtered, so the fine grind helps create a rich, thick brew.
Choosing the Right Grinder
A quality grinder is crucial for consistent results. Here are the two main types:
- Blade Grinders: Affordable but inconsistent. They chop beans unevenly, leading to uneven extraction.
- Burr Grinders: The gold standard. They grind beans evenly for better flavour, balance, and control.
For the best results, use a burr grinder—either manual or electric—for precise control over your grind size.
Common Grinding Mistakes & How to Fix Them
1. Your Coffee Tastes Too Bitter
- Problem: Over-extraction from a grind that’s too fine.
- Solution: Try a slightly coarser grind for slower extraction.
2. Your Coffee Tastes Sour or Weak
- Problem: Under-extraction from a grind that’s too coarse.
- Solution: Use a finer grind for better flavour balance.
3. Your Espresso Is Pulling Too Slowly or Quickly
- Problem: A grind that’s too fine (slow shot) or too coarse (fast shot).
- Solution: Adjust grind size slightly to achieve a balanced espresso extraction.

Exploring More About Coffee Grinding
1. How do I store my coffee beans for the best flavour?
To keep your coffee fresh, store beans in an airtight container away from light, heat, and moisture. Avoid keeping them in the fridge, as they can absorb unwanted odours.
2. Should I grind coffee in advance or right before brewing?
For the freshest flavour, grind your coffee right before brewing. Pre-ground coffee can lose its aroma and taste within hours.
3. What’s the best way to experiment with different grind sizes?
Try brewing the same coffee beans using different grind settings and taste the difference. Keep notes on the extraction time, flavour, and strength to refine your brewing method.
4. Can I use a spice grinder for coffee beans?
Technically, yes, but it’s not recommended. Spice grinders use blades that chop inconsistently, leading to an uneven grind that affects extraction.
5. What’s the best grind size for a balanced cup of coffee?
A medium grind is a safe starting point, as it works well for most drip coffee makers and pour-over methods. From there, adjust finer or coarser based on taste and brew time.
