How to Make Coffee with a French Press the Right Way

If you’ve ever used a French press and ended up with sludgy, bitter coffee, you’re not alone. The problem isn’t the method—it’s how it’s done. The French press, or press pot, is one of the most straightforward brewing devices, yet small mistakes in grind size, water temperature, or timing can ruin your cup. Here’s how to get it right every time.

To make great coffee with a French press, use 15 grams of coffee per cup, a coarse grind like coarse sugar or gravel (EK43s setting 10.5 / hand grinder 26), water at 92–95°C, and steep for 3 to 6 minutes depending on temperature. The standard brew ratio is 1:15 (9–10g coffee per 150ml water).

What Is a French Press and Why Use It?

The French press, also known as a press pot or plunger pot, is one of the most widely used manual coffee brewing methods, especially in France and across Europe. According to Mr. Kramer, founder of the European Specialty Coffee Association, it’s valued for its ability to fully express the character of the coffee bean—both its strengths and flaws. It’s a full-immersion brewing method, meaning the coffee grounds sit in hot water for several minutes before being filtered out. This results in a rich, full-bodied cup with more oils and sediment than other methods.

How the French Press Works: Immersion Brewing Explained

Unlike pour-over or drip methods, the French press uses immersion brewing. Coarse-ground coffee is fully submerged in hot water, usually for around 3 to 6 minutes. The metal mesh filter allows more oils and fine particles to pass through compared to paper filters, giving the coffee a heavier mouthfeel and bolder flavor. However, this also means that if the grind is too fine or the brew time too long, you’ll get over-extracted, bitter coffee with a lot of sediment.

Step-by-Step: How to Brew Coffee with a French Press

To brew coffee properly with a French press, follow these exact steps:

• Equipment Needed: French press (300cc size recommended), hand or electric grinder, fresh coffee beans (30g total for 2 cups), kettle, timer, and a cup.
• Grind Size: Use a coarse grind, similar to coarse sugar or small gravel. For an EK43s grinder, set it to 10.5; for a hand grinder, aim for around setting 26. The grounds should be coarse enough that they don’t pass through the metal filter.
• Coffee Dose: Use 15 grams of coffee per cup. For a standard 300cc press, 30 grams is typical for two cups.
• Water Temperature: Heat your water to 92–95°C. If your kitchen is cold (below 20°C), pre-warm the French press with hot water for about a minute before brewing to maintain a stable temperature.
• Bloom (Optional): While not always done in French press brewing, you can pour a small amount of water to let the coffee bloom briefly before adding the rest.
• Add Coffee & Water: Add 15g of coffee per cup (30g total for 2 cups) into the preheated French press. Pour in 150ml of hot water per 15g of coffee (around 450ml total for 30g). Stir gently to ensure all the grounds are saturated.
• Steeping Time: Place the lid on with the plunger pulled up. Let the coffee brew for 3 to 6 minutes. If your water is cooler, lean toward 5–6 minutes. If it’s hotter, 3–4 minutes is better. Adjust time to balance extraction without over-brewing.
• Pressing the Plunger: After the brew time, press the plunger down slowly and steadily. Avoid pressing too quickly, which can agitate the grounds and increase bitterness.
• Serving: Pour the coffee immediately into your cup to avoid over-extraction from the grounds sitting on the bottom. Preheat your cup with hot water for best results.

Key Variables That Affect Your French Press Coffee

Several factors determine the outcome of your French press brew:

• Grind Size: Too fine, and you’ll over-extract and get bitter coffee with lots of sludge. Too coarse, and you’ll under-extract, resulting in weak, sour coffee. Aim for a coarse grind that resembles cracked pepper or gravel.
• Water Temperature: The ideal range is 92–95°C. Lower temperatures may require longer steeping (up to 6 minutes), while higher temperatures can extract faster, so reduce time to 3–4 minutes. Without a thermometer, let boiled water sit for 2–3 minutes before using.
• Brew Time: Most brewers find 3 to 4 minutes ideal for medium roasts. Darker roasts can go up to 5–6 minutes, but watch for bitterness. Adjust based on taste and temperature.
• Coffee-to-Water Ratio: The recommended starting ratio is 1:15—that’s 9–10 grams of coffee for every 150ml (5oz) of water. For a stronger cup, increase the coffee slightly.

Common Mistakes to Avoid

• Using Too Fine a Grind: A fine grind will lead to over-extraction and allow coffee particles to pass through the filter, resulting in a muddy cup.
• Incorrect Water Temperature: Water that’s too hot can scorch the coffee, while water that’s too cool won’t extract enough flavor. Aim for 92–95°C.
• Over-Steeping: Letting the coffee sit too long (more than 6 minutes) leads to bitterness and over-extraction.
• Not Pressing Slowly: A fast plunge disturbs the grounds and can push bitter fines through the filter.
• Leaving Coffee in the Pot: Don’t let brewed coffee sit in the French press after pressing—it will continue to extract and turn bitter. Pour it out immediately.

Expert Tips for Better French Press Coffee

• Use freshly roasted, high-quality coffee beans. Freshness matters more in immersion brewing due to longer contact time.
• Preheat both your French press and your cup to maintain temperature stability.
• Stir the coffee after pouring water to ensure even saturation.
• If you prefer a lighter or fruitier cup, choose a medium roast. For deeper, richer flavors, a dark roast works better in a French press.
• Clean your French press thoroughly after each use to avoid old coffee oils affecting future brews.

Frequently Asked Questions

What’s the best grind size for a French press?

The ideal grind size for a French press is coarse—similar to cracked pepper or gravel. For an EK43s grinder, use setting 10.5; for a hand grinder, aim for around 26. This prevents fine particles from passing through the metal filter and making the coffee gritty or bitter.

What water temperature should I use for French press coffee?

Use water heated to 92–95°C. If you don’t have a thermometer, let boiled water sit for 2–3 minutes before brewing. In cooler kitchens (below 20°C), pre-warm the French press with hot water to help stabilize the brew temperature.

How long should I let coffee brew in a French press?

Most brewers use a steep time of 3 to 6 minutes. For water around 92–95°C, 3–4 minutes is ideal. If your water is cooler, steep closer to 5–6 minutes. Adjust based on taste and roast level.

What’s the best coffee-to-water ratio for French press?

A good starting ratio is 1:15—that’s 9–10 grams of coffee per 150ml (5oz) of water. For a 300cc French press with 30 grams of coffee, use about 450ml of water. Adjust to taste, increasing coffee for a stronger brew.

Can I use finely ground coffee in a French press?

No, avoid finely ground coffee. It will pass through the metal filter, creating a murky, gritty cup. Always use a coarse grind to ensure proper filtration and avoid over-extraction.
