How to Make Coffee with a French Press

If you’ve ever made coffee with a French press and ended up with a sludgy cup or weak flavor, you’re not alone. Many assume the French press is foolproof, but subtle missteps in grind size, water temperature, and timing can ruin your brew. This guide breaks down exactly how to use a French press the right way—step by step.

To brew coffee with a French press, use 10 grams of coarse-ground coffee per 100 milliliters (about 3.4 oz) of water. For a standard 350 ml French press, use roughly 22 grams of coffee and water heated to around 92°C (198°F). Steep for 4 minutes, then press slowly and pour.

What Makes French Press Coffee Different?

The French press is an immersion brewer, meaning coffee grounds soak directly in hot water. Unlike pour-over or drip methods, there’s no constant flow or mechanical filtration—just a metal mesh filter that lets more oils and fine particles through. That gives French press coffee a fuller body, richer mouthfeel, and more sediment. But it also means you have to control grind coarseness and brewing time carefully, or you’ll get over-extracted bitterness or a muddy cup.

The Right Grind Size for French Press

FrontStreet Coffee recommends using a grind size similar to coarse sea salt or coarse sugar. For electric grinders like the EK43s, that’s around setting 10.5; for hand grinders, it’s about setting 26. This produces a texture like small gravel—not powder or sand. Grinding too fine risks letting coffee particles slip through the filter, resulting in a gritty, over-extracted brew. If you want more complexity, you can try a slightly finer grind—but reduce the steep time to avoid over-brewing.

Water Temperature & Ratio

Use water heated to approximately 92°C (198°F). To get this without a thermometer, let boiled water sit with the lid off for about 1 minute. The ideal brew ratio is 1:15—that’s 1 gram of coffee per 15 grams (milliliters) of water. For a 350 ml French press, that means around 22–23 grams of coffee and 350 ml of water. This ratio yields a balanced strength of around 1.1–1.2% TDS, producing a rich and full-bodied cup.

How to Brew Coffee with a French Press (Step-by-Step)

Follow these steps for a clean, full-flavored French press brew:

• Preheat Your Equipment (Optional but Helpful): Pour hot water into the empty French press and plunger, then pour it out after half a minute. Do the same with your mug to maintain brew temperature.
• Add Coffee Grounds: Place 10 grams of coarse-ground coffee per 100 ml of water into the French press. For a 350 ml press, that’s about 22 grams.
• Pour Hot Water: Start your timer as you pour water heated to about 92°C over the grounds. Fill to your desired level. Optional: give the slurry a gentle stir with a spoon to ensure even saturation.
• Steep: Let the coffee brew for 4 minutes. If using lower-quality water pressure (like from a water cooler), extend to 5 minutes.
• Press Slowly: After 4 minutes, gently press the plunger down in a slow, steady motion. Avoid pushing too fast, which can stir up sediment.
• Pour and Serve: Pour all the coffee into your mug immediately to avoid over-extraction from the grounds sitting in the brew.

3 Tips for Better French Press Coffee

Here are three expert tips to improve your French press brew:

• Preheat Everything: Rinse your French press and mug with hot water before brewing. This helps keep your coffee hotter for longer and improves extraction consistency.
• Use the Right Dose: Stick to the rule of one level scoop (usually around 10 grams) per cup. A standard coffee scoop that comes with many French presses holds roughly that amount.
• Stir for More Extraction: If you have time, give the coffee-water mixture a clockwise stir for three rotations right after pouring. This ensures all the grounds are fully saturated and leads to a richer, more balanced cup.

Frequently Asked Questions

What is the best coffee grind size for a French press?

The ideal grind size is coarse—similar to sea salt or coarse sugar. For electric grinders like the EK43s, set to around 10.5; for hand grinders, about 26. This prevents fine particles from slipping through the metal filter and making your cup gritty.

What water temperature should I use for French press coffee?

Use water at approximately 92°C (198°F). If you don’t have a thermometer, let boiled water sit with the lid off for about 1 minute to cool slightly before pouring over the coffee grounds.

How much coffee should I use per cup in a French press?

A general guideline is 10 grams of coffee per 100 milliliters (about 3.4 oz) of water. For a standard 350 ml French press, use around 22 grams of coffee. That’s roughly one heaping tablespoon or coffee scoop per “cup” (though a coffee scoop varies).

How long should I let French press coffee steep?

Steep your French press coffee for 4 minutes for best results. If you’re using water from a less powerful source (like a water cooler), extend the time to 5 minutes. Avoid going longer unless you want bitter, over-extracted flavors.

Can I use a finer grind in a French press?

You can use a slightly finer grind if you prefer more flavor complexity, but reduce the steep time accordingly to avoid over-extraction. Be aware that finer grinds may allow more silt through the filter, leading to a cloudier, grittier cup.

Do I need to stir the coffee during brewing?

Stirring is optional but recommended for better extraction. Give the coffee a gentle stir for three rotations right after pouring the hot water to ensure all the grounds are saturated evenly.
