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

If you’ve ever walked into a coffee shop in the West and seen a tall cylindrical metal and glass brewer with a plunger, you've probably encountered a French press—even if no one called it that. In China, similar devices are often marketed as tea plungers, but in the specialty coffee world, it’s a classic immersion brewer used to make full-bodied, rich coffee. So what exactly is a French press, and why does it create such a distinct cup?

A French press, or coffee plunger, is a simple immersion brewer where coarse-ground coffee steeps in hot water for several minutes, then is separated by pressing down a metal filter. The standard dose is around 80 grams of coffee per liter of water, and ideal brewing temperature is between 91–96°C. Total brew time is around 3 minutes.

What Is a French Press?

Also known as a coffee plunger or press pot, a French press is a manual coffee brewing device that combines coffee grounds and water in a single container. It features a cylindrical glass or metal carafe, a plunger with a metal mesh filter, and a lid. Unlike pour-over or drip methods, the coffee and water steep together, allowing for full immersion. This method is valued for highlighting both the strengths and flaws of a coffee’s flavor profile, making it a revealing way to taste a bean’s character.

How the French Press Brewing Method Works

The French press uses an immersion brewing style, meaning coffee grounds remain fully submerged in hot water throughout the brew. This allows for even and thorough extraction, as all the coffee interacts with the water over the entire brew period. The metal filter lets more oils and fine particles through than paper filters, contributing to a heavier body and a more robust mouthfeel. However, it also means some sediment may end up in your cup. Because the coffee and water are not separated until the end, the final flavor includes both the bright and bitter characteristics of the coffee—offering a very transparent picture of the bean’s qualities.

Step-by-Step: How to Use a French Press

To brew with a French press, follow these key parameters drawn directly from specialty practice:

• Coffee Dose: Use approximately 80 grams of coffee per liter (or per “cup” as traditionally defined in the method). Do not exceed the maximum capacity of your specific French press.
• Grind Size: Grind your coffee to a coarse consistency that matches the requirements of immersion brewing—similar to coarse sea salt. This helps prevent over-extraction and minimizes fine particles passing through the filter.
• Water Temperature: Heat your water to between 91–96°C (196–205°F). This range is ideal for extracting the full range of flavors without scorching the grounds.
• Bloom & Steeping: Add hot water to the grounds, filling the French press to just below the bottom of the metal filter frame. Place the plunger on top (do not press yet) and let the coffee steep for 3 minutes.
• Pressing: After 3 minutes, press the plunger down slowly and steadily until it reaches the bottom. This separates the grounds from the brewed coffee.
• Serving: Pour the coffee immediately into cups or a separate carafe to avoid over-extraction from any remaining grounds in contact with the liquid.

These steps ensure proper extraction and a balanced cup. The metal filter allows natural coffee oils and some fine sediment into your cup, which contributes to the body but also means a slight residue may remain.

Why Use a French Press?

The French press is favored for its simplicity, full flavor, and ability to highlight the inherent traits of the coffee. Because it’s an immersion method, it tends to produce a cup with more body and texture than paper-filtered methods. The inclusion of oils and micro-sediments can enhance the richness, making it especially good for showcasing darker roasts or coffees with naturally bold profiles. However, it can also emphasize any defects in the beans, making it a true reflection of the coffee’s quality.

Frequently Asked Questions

What is another name for a French press?

In China, it’s commonly called a “” (coffee brewing device) or “” (tea plunger), while in Western countries it’s known as a French press or coffee plunger. The term “Prench Press” (likely a phonetic misunderstanding of “French Press”) is also used informally.

What grind size should I use for a French press?

Use a coarse grind, similar to coarse sea salt. This prevents over-extraction and reduces the amount of fine particles that pass through the metal filter, which can lead to a gritty cup.

What is the ideal water temperature for French press coffee?

The recommended water temperature is between 91–96°C (196–205°F). This range extracts the optimal flavors from the coffee without risking bitterness from overheating.

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

The standard ratio is around 80 grams of coffee per liter of water. For a typical single-serving French press (about 300–400 ml), this equates roughly to 24–32 grams of coffee.

How long should you steep coffee in a French press?

The coffee should steep for about 3 minutes after adding hot water and placing the plunger on top (without pressing). This timing allows for balanced extraction.

Does a French press make strong coffee?

Yes, French press coffee is typically stronger and fuller-bodied than many other brewing methods due to the immersion process and the presence of natural oils and fine sediment in the cup.

Do you need a special filter for a French press?

No, the French press comes with a built-in metal mesh filter attached to the plunger. It filters out most of the coffee grounds but allows oils and some fine particles to pass through.
