How to Use a French Press: Step-by-Step Coffee Brewing Guide

Making coffee with a French press seems simple, but many home brewers still end up with over-extracted bitter notes, sludgy grounds in their cup, or weak, underwhelming brews. If you've ever wondered why your French press coffee doesn’t taste as clean or rich as it should—or how to get it just right—this guide breaks down everything you need to know.

To brew coffee with a French press the right way, use 10g of coarse coffee per 150ml water, 92°C hot water, a 1:15 brew ratio, and steep for exactly 5 minutes before pressing slowly. Adjust grind size, time, or water temp as needed based on roast level or water source.

What Is a French Press and How Does It Brew Coffee?

A French press, also called a coffee plunger, is an immersion brewer that steeps coarsely ground coffee in hot water before separating the grounds by pressing a metal filter. Because the coffee and water sit together for several minutes, the resulting brew tends to be full-bodied, rich, and higher in natural oils and sediment. This method highlights heavier, sweeter, and more rounded flavors, especially from medium to dark roasts.

The Correct Way to Use a French Press Step by Step

Here’s the exact process to follow for consistent results every time:

• Start by removing the lid and plunger (the filter screen is attached).
• Add your freshly ground coffee—about 10g per person, or one standard French press scoop.
• Pour in 92°C water (just off boil, or boiled then left to sit for one minute). Fill to your desired level, such as two cups (approx. 300ml total).
• Place the lid on with the plunger pulled all the way up—but do not press yet. Start a timer immediately.
• After exactly 5 minutes, slowly press the plunger down. Pour the coffee out into cups right away to avoid over-extraction from sitting on the grounds.

Key Factors That Affect Your French Press Coffee

Coffee-to-Water Ratio and Volume

Most French presses come with measurement markers for cups (usually around 150ml each). Use one level scoop (10g) of coffee per person or cup. For two cups, add two scoops and fill to the two-cup mark with water. A common starting ratio is 1:15 (15g coffee per 225ml water), giving a strong but smooth cup.

Grind Size: Why Coarse Matters

Your coffee must be ground to a coarse texture—roughly like coarse sea salt or slightly larger than white sugar. If using a hand grinder, aim for around setting 26; for electric grinders like the EK43s, that’s around setting 10.5. This prevents fine particles from slipping through the metal filter and making your cup gritty. A too-fine grind can also over-extract and make the coffee bitter.

Water Temperature: Why 92°C Is Ideal

Use water at 92°C for optimal extraction. That’s easy to hit: just let your boiling water rest off the heat for one minute. If you’re using lower-temp water (like from a thermos or water cooler), extend the brew time to 6–7 minutes instead of 5 to ensure proper extraction.

Brew Time: Stick to 5 Minutes (Usually)

Five minutes is the sweet spot for water at 92°C. If your water is cooler (e.g., from a thermos), go for 6–7 minutes. Don’t go shorter unless you’re using a very dark roast and want to reduce bitterness—but even then, adjust grind or ratio first.

Pressing the Plunger: Do It Slowly

When it’s time to press, do it gently and steadily. A slow press minimizes agitation, which helps avoid churning up coffee grounds and pushing fine sediment into your cup. Quick or forceful pressing leads to cloudy, gritty coffee.

What Makes French Press Coffee Different?

French press coffee tends to be richer and fuller-bodied than pour-over or drip coffee because it’s fully immersed. The metal filter allows natural oils and tiny coffee particles to pass through, enhancing texture but also leaving a bit of sediment. It won’t be as clear as coffee from a paper-filtered method, but many drinkers prefer the heavier mouthfeel and bold flavors it produces.

Frequently Asked Questions

What is the ideal coffee-to-water ratio for French press?

A good starting ratio is 1:15—that’s 10g of coffee per 150ml (about one cup) of water. For two cups, use 20g coffee and 300ml water. You can adjust up or down depending on taste preference, roast level, or brew strength.

What grind size should I use for French press?

Use a coarse grind, similar to coarse sea salt or slightly larger than white sugar. On a hand grinder, aim for around setting 26; for electric grinders like the EK43s, that’s around 10.5. This prevents fine particles from getting through the filter and making your coffee gritty.

What water temperature is best for French press coffee?

The optimal water temperature is 92°C. You can get this by letting boiling water sit off the heat for one minute. Avoid using water that’s too cool unless you extend brew time to 6–7 minutes.

How long should I steep coffee in a French press?

Steep for exactly 5 minutes when using 92°C water. If your water is cooler (e.g., from a thermos), increase the time to 6–7 minutes to ensure proper extraction.

Why does my French press coffee have so much sediment?

Sediment happens because the metal filter lets fine coffee particles through. Using a coarse grind and pressing slowly helps minimize it. Always pour your coffee out after pressing to avoid further extraction and settling.

Can I use a French press for light roast coffee?

You can, but light roasts tend to produce more acidity and delicate flavors that may get lost or muted in a French press. The method works better with medium to dark roasts, which develop sweeter, richer, and more robust profiles.
