French Press Coffee: How the French Brew Their Daily Cup

Ever wondered why your French press coffee tastes murky or overly bitter? Despite being one of the simplest brewing methods, the French press is easy to mess up—if you don’t get the grind, water temperature, or timing right, you’ll end up with either under-extracted sourness or over-extracted sludge.

To brew great coffee with a French press, use 15 grams of coffee per cup (about 30g for two), grind to a coarse, sand-like consistency, and steep in 92–95°C water for 3 to 6 minutes. Then press gently and pour immediately to avoid over-extraction.

What Is a French Press and Why Use It?

The French press—also called a press pot or cafetière—is one of the most hands-off yet effective ways to brew coffee. According to European Specialty Coffee Association founder Mr. Kramer, it’s a device that highlights the true character of the coffee bean. Its full-immersion design allows all the flavours to develop evenly, making it ideal for showcasing both high-quality and everyday beans.

Though often called a "" (tea maker) in China, the French press is built for coffee. Every variable—from grind size to brew time—is controlled by you, making it both simple and highly adjustable.

How the French Press Works: Immersion & Filtration

The French press uses a metal mesh filter that lets more coffee oils and fine particles through compared to paper filters. This creates a heavier, fuller-bodied cup with more texture. But it also means fine coffee grounds can make it into your drink if the grind is too fine or the plunger isn’t pressed carefully.

Because it fully immerses coffee grounds in hot water, extraction is even but requires proper timing. Too short, and you’ll under-extract; too long, and bitterness sets in.

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

To make two cups (about 300ml total) using a 300cc French press (model CKJ-300):

• Grind: Use 30 grams of quality coffee beans, ground to a coarse size—similar to coarse sea salt or slightly finer than gravel. It should be too coarse to pass through the filter easily.
• Water: Heat filtered water to 92–95°C (just off boil). If the room is cold (below 20°C), pre-warm the French press by rinsing it with hot water for about a minute before brewing to stabilise the brew temperature.
• Dosing: Add 15 grams of coffee per cup (so 30g for two cups) into the pre-warmed French press.
• Blooming & Pouring: Start by pouring a small amount of water to let the coffee bloom, then add the rest of the water (around 450–480ml total for a 1:15 ratio, though 1:14–1:16 is acceptable). Stir gently if needed, then place the lid on with the plunger pulled all the way up.
• Steep: Let the coffee brew for 3 to 6 minutes depending on your taste and water temperature. Lower water temps may need closer to 6 minutes; higher temps may only need 3.
• Press & Pour: After steeping, press the plunger down slowly and steadily. Pour the coffee into cups immediately to avoid over-extraction from sitting on the grounds.

Grind Size, Ratio, and Timing: Key Variables

Your French press results hinge on three things:

1. Grind Size: Must be coarse—like cracked pepper or coarse sugar. Too fine, and you’ll get bitter sludge as fines pass through the filter. Use a grind similar to table salt or slightly larger. For electric grinders like the EK43s, aim for setting 10.5; for hand grinders, around setting 26.
2. Brew Ratio: Standard is 9–10 grams of coffee per 150ml (about 1:15 to 1:16). For stronger coffee, increase coffee amount within that range.
3. Steeping Time: 3 to 6 minutes. Shorter for brighter flavours, longer for fuller extraction—but adjust based on actual water temperature. If your water is cooler than 92°C, steep longer; if hotter than 95°C, go shorter.

Common Mistakes to Avoid

• Using too fine a grind—leads to over-extraction and sludgy coffee.
• Not pre-warming your French press—causes temperature to drop too fast.
• Letting it steep too long—results in bitter, over-extracted flavours.
• Pressing the plunger too hard or too quickly—can agitate grounds and worsen extraction.
• Leaving brewed coffee in the French press after pressing—leads to continued extraction and bitterness.

Frequently Asked Questions

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

The ideal French press grind is coarse—similar to sea salt or coarse sugar. It should be too large to pass easily through the metal filter. For an EK43s electric grinder, use setting 10.5; for hand grinders, aim for around setting 26. Avoid going finer, or you’ll get bitter coffee with lots of sediment.

How much coffee should I use in a French press?

Use about 9–10 grams of coffee per 150ml of water. For a standard 300ml French press, that’s roughly 15–18 grams per cup, or 30 grams for two cups total. Adjust up for a stronger brew, but keep the brew time and grind size balanced.

What water temperature is ideal for French press?

The recommended water temperature is 92–95°C, just off a boil. If your tap water is cooler, increase brew time slightly; if hotter, reduce brew time to avoid over-extraction. Without a thermometer, let boiled water sit for 2–3 minutes before using.

How long should I let French press coffee steep?

Steep for 3 to 6 minutes. Start with 4 minutes as a baseline. Use shorter times for lighter roasts or higher temperatures, and longer for darker roasts or cooler water, but always adjust based on taste and conditions.

Can I use light roast coffee in a French press?

Light roasts can be used, but they often highlight more acidity and delicate flavours that may not shine as well in a French press. The method works better with medium or dark roasts, which produce richer, sweeter, and more caramelised notes. If using a light roast, keep the grind coarse and don’t over-brew.
