A beginner’s guide to bold, balanced coffee without bitterness
If your French press coffee tastes bitter, weak, or like muddy water, you’re not alone. While it’s one of the most beginner-friendly french press brewing methods, the French press (or cafetière) is also one of the most misunderstood. The truth is: the difference between a perfect cup and a disappointing one comes down to just two things — ratio and timing.
This guide covers exactly how to brew French press coffee with confidence. Whether you’re just switching from instant or fine-tuning your technique, you’ll learn: the perfect coffee-to-water ratio (with UK measurements), brew time based on bean type and grind size, and simple tips to avoid over-extraction and bitterness. No fluff, no faff — just great coffee.
What Is a French Press?
A French press brewing is a manual coffee brewer consisting of a cylindrical glass or stainless steel container, a plunger, and a metal mesh filter. It brews by steeping ground coffee in hot water and pressing the grounds to the bottom after extraction.
It’s popular because it’s affordable, easy to use, great for brewing multiple cups at once, and excellent at extracting rich, full-bodied flavour.

The Perfect French Press Brewing Ratio (UK-Friendly)
Getting your coffee-to-water ratio right is key to flavour. Too little coffee? It’ll be weak and sour. Too much? Bitter and overpowering.
Standard Ratio: 1:15 to 1:17
| Cups | Coffee (g) | Water (ml) |
|---|---|---|
| 1 | 15g | 225ml |
| 2 | 30g | 450ml |
| 3 | 45g | 675ml |
| 4 | 60g | 900ml |
Best practice: Start with a 1:16 ratio and adjust based on your beans and taste preferences.

Step-by-Step: How to Perfect French Press Brewing
1. Preheat Your French Press
Rinse it with hot water to warm the glass and prevent temperature loss.
2. Weigh and Grind Your Coffee
Use coarse grind — about the texture of sea salt. Too fine, and you’ll get over-extraction and silty coffee.
3. Add Coffee to the Press
Use a scale if possible — 30g of coffee for 450ml of water is a great starting point.
4. Pour in Hot Water (92–96°C)
Let it sit for 30 seconds, then stir gently to break up the crust. Pour up to your full water ratio and start your timer.
5. Steep for 4 Minutes
Leave it alone. Don’t plunge yet. This is where the magic happens.
6. Skim the Surface Foam (Optional)
This can reduce bitterness — some baristas do this for cleaner flavour.
7. Press Slowly and Steadily
Use two hands if needed. If the plunger is too hard to push, your grind is too fine.
8. Pour and Enjoy Immediately
Don’t let the coffee sit in the French press — it continues to steep and will become bitter.

Common French Press Mistakes (And How to Fix Them)
| Mistake | What Happens | Fix |
|---|---|---|
| Grind too fine | Bitter and silty coffee | Use a coarse grind |
| Steep too long | Over-extracted, harsh flavour | Stick to 4 mins |
| Coffee too weak | Thin and sour | Use more coffee (lower ratio) |
| Letting it sit after pressing | Bitter over time | Decant immediately |
How to Clean a French Press (Properly)
- Disassemble the plunger and mesh
- Rinse grounds into compost bin (not sink!)
- Wash with warm water and mild soap
- Let dry fully before reassembling
- Descale occasionally if using hard water
