How to Use a French Press to Brew Coffee

If you’ve ever used a French press and ended up with sludgy coffee or bitter over-extraction, you’re not alone. Many coffee drinkers struggle to get consistent results from this simple-looking brewer. The good news? Once you understand how it really works, the French press can produce rich, full-bodied coffee with surprising clarity.

To brew with a French press, use 20 grams of coarse coffee, add 200 ml of 91°C water, stir after 3–4 minutes, steep for a total of 7 minutes, then press and serve. That’s the basic formula — but grind size, water quality, and timing all matter.

What Is a French Press and How Does It Work?

A French press, also called a cafetière, coffee plunger, or filter press, dates back to 1850. Originally made of glass with a metal mesh filter and plunger, it’s a full-immersion brewing device. Hot water steeps directly with coffee grounds, allowing oils and flavours to fully extract. Then the plunger pushes the grounds to the bottom, separating them from the brewed coffee. The result is a rich, heavy-bodied cup with more sediment than filtered methods.

Why Grind Size and Brewing Time Matter in a French Press

The French press uses a metal filter, which lets more fine particles (fines) pass through compared to paper filters. This contributes to a heavier mouthfeel but also means grind size is critical. If your coffee is ground too fine, it can over-extract and lead to bitterness, or allow too many fines into your cup. For best results, use a coarse grind similar to sea salt or coarse sugar — about the texture of small gravel. On an EK43 grinder, that’s around setting 10.5; for hand grinders, aim for setting 26. This helps prevent over-extraction and excessive sediment.

Step-by-Step: How to Use a French Press the Right Way

Follow these steps for a balanced, clean cup:

• Preheat your French press and cup with hot water, then discard the water.
• Add 20 grams of coarse-ground coffee (medium to dark roast preferred).
• Pour 200 ml of water at around 91°C over the grounds. Start with the French press tilted 45 degrees and pour in stages.
• Let it sit for 3–4 minutes, then gently stir the grounds with a bamboo or non-metallic stirrer for about 10 seconds.
• Place the plunger on top (don’t press yet) and let the coffee steep for a total of 7 minutes (including the initial rest).
• After 7 minutes, slowly press the plunger down all the way.
• Pour immediately into your preheated cup to avoid over-extraction from sitting on the grounds.

This process gives you a 1:10 brew ratio (20g coffee : 200ml water), though many use a standard 1:15 (e.g., 15g coffee to 225ml water) for a lighter cup. Adjust to taste.

Choosing the Right Coffee for French Press

Because French press is an immersion brew method with longer contact time, medium to dark roasts tend to perform better. They highlight sweetness and body without getting overly bright or acidic. Light roasts can work but may taste too sharp or grassy unless you adjust grind and time carefully.

For a fragrant, fruity profile, try a medium roast with notes of berry and citrus. For deeper, comfort flavours, go for a dark roast with hints of chocolate, caramel, and spice. Avoid very light or delicate beans unless you’re experimenting with shorter steep times and coarser grinds.

Freshness, Water Quality, and Common Mistakes

Use freshly ground coffee for the best flavour — pre-ground beans lose aroma quickly. Always use filtered water if possible; water quality has a huge impact on taste. Avoid using boiling water (over 93°C), which can scorch the grounds and cause bitterness.

Common mistakes include:

• Using too fine a grind (leads to over-extraction and sludge).
• Not stirring after initial pour (uneven extraction).
• Pressing the plunger too hard or too fast (increases fines in cup).
• Letting it steep too long (bitterness).
• Leaving coffee in the French press after pressing (it continues extracting and gets stronger/bitter).

Frequently Asked Questions

What is the ideal grind size for French press coffee?

The ideal grind size for a French press is coarse — similar to sea salt or coarse sugar. On an EK43 grinder, use setting 10.5; for hand grinders, aim for around setting 26. This prevents over-extraction and minimizes coffee fines in your cup.

How much coffee should I use in a French press?

A standard brew uses 20 grams of coffee for 200 ml (about 7 ounces) of water. This is roughly a 1:10 brew ratio. Many brewers also use a 1:15 ratio (e.g., 15g coffee to 225ml water) for a lighter extraction. Adjust based on taste preference.

What water temperature is best for French press?

The recommended water temperature is around 91°C. If you don’t have a thermometer, let boiled water cool for about 2–3 minutes. Avoid using boiling water (100°C), which can over-extract and cause bitterness.

How long should French press coffee steep?

Total steep time is around 7 minutes: let the coffee sit for 3–4 minutes after pouring, stir the grounds, then steep with the plunger on top for another 3–4 minutes before pressing. Some prefer a shorter or longer brew (4–5 minutes total), but 7 minutes is a reliable standard.

Can I use light roast coffee in a French press?

Yes, but light roasts can taste overly bright or grassy in a French press due to the long steep time. If using a light roast, opt for a coarser grind and shorter steep time, or choose a fruitier, more soluble bean. Medium to dark roasts generally work better.
