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

If you’ve ever heard someone call a French Press a ‘tea strainer for coffee’ or wondered why your cup tastes overly bitter or sludgy, you’re not alone. Many coffee drinkers first encounter the French Press as a mysterious metal contraption that promises strong coffee—but delivers mixed results. The truth? This simple device is one of the clearest ways to taste both the virtues and flaws in your coffee beans.

In short, a French Press—also known as a 'Prench Press' in some Chinese contexts—is a traditional immersion coffee brewer. You use coarse coffee ground specifically for it, typically at a ratio of 80 grams per liter, steeped in water at 91–96°C for 3 minutes, then separated with a plunger. That’s the whole method.

What Is a French Press, Really?

Despite often being called a 'tea press' in China, where it’s mainly used for brewing tea, the French Press is globally recognised as a coffee brewing device. In English-speaking countries, it’s called a French Press—or sometimes, confusingly, a 'Prench Press' in Chinese translations. It’s a cylindrical glass or metal container with a built-in plunger and metal mesh filter. The coffee grounds and hot water steep together, allowing full immersion before the plunger is pressed down to separate the grounds from the brewed coffee.

Why Use a French Press?

The French Press is valued for its simplicity and its ability to highlight the full spectrum of coffee characteristics—both good and bad. Because it uses full immersion brewing and a relatively coarse grind, it tends to produce a fuller-bodied cup than paper-filter methods like pour-over. But it also leaves more oils and fine particles in the cup, which can accentuate any defects in the beans or roast. That makes it a great tool for learning what your coffee really tastes like, unfiltered.

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

To make coffee with a French Press the standard way, follow these exact parameters:

• Grind Size: Use coffee ground to match the coarseness needed for a French Press—typically quite coarse, similar to sea salt.
• Dose: Add approximately 80 grams of coffee per liter (or per 1000 ml) of water. That translates to about 40 grams for a standard 500 ml French Press.
• Water Temperature: Heat your water to between 91°C and 96°C (195°F–205°F).
• Bloom (Optional): Though not mentioned in the source, many brewers gently pour a little water to let the coffee bloom before adding the rest.
• Steeping Time: Pour water up to the metal frame at the top of the Press’s handle. Add the coffee, stir if desired, then place the lid on with the plunger pulled up. Let it steep for exactly 3 minutes.
• Pressing: After 3 minutes, press the plunger down slowly and steadily until the filter reaches the bottom. Serve immediately.

Common Mistakes to Avoid

Using too fine a grind can lead to over-extraction and a muddy, bitter cup, while too coarse may under-extract and leave your coffee weak. Also, letting the coffee sit in the press after pressing will continue to extract bitter compounds, so always pour it out right away. Using water that’s not hot enough—or too hot—will also significantly change the results.

What the French Press Reveals About Your Coffee

Because there’s no paper filter, everything that’s in the cup is a direct result of the beans, roast, grind, and brew. That means brightness, sweetness, body—and any off-flavors—are fully present. It’s one of the most transparent ways to evaluate a coffee’s true profile, especially if you’re experimenting with single origins or different roast levels.
