How to Use a French Press to Brew Coffee

If you’ve ever tried making coffee with a French press and ended up with bitter sludge or weak, murky liquid, you’re not alone. Many people struggle with this simple-looking brewer, unsure of how long to steep, how coarse the grind should be, or what water temperature works best. The truth is, French press coffee can be rich, full-bodied, and delicious—but only if you control the fundamentals.

To brew coffee with a French press the right way, use a coarse grind (like cracked pepper or coarse sea salt), a 1:15 coffee-to-water ratio (e.g., 15g coffee to 225g water), water just off boil (~90°C or 195°F), and steep for around 4 minutes. Adjust based on your taste and coffee roast level.

What Is a French Press and How Does It Work?

The French press, also known as a coffee plunger or French filter (in Chinese, ), is a simple, cylindrical brewing device made of heat-resistant glass (or sometimes plastic) with a metal mesh plunger and filter. It originated in France around 1850 and was originally used for tea—hence its other nickname, the ‘tea press.’

Unlike pour-over or espresso methods, the French press uses full immersion brewing. This means coffee grounds soak directly in hot water for several minutes, allowing for a fuller extraction through gentle, even saturation. The metal filter lets more oils and fine particles into the cup, resulting in a heavier mouthfeel and richer body.

Why Grind Size Matters in a French Press

Grind size is one of the most critical factors in French press brewing. Because the coffee is fully immersed and not filtered through paper, using too fine a grind can lead to over-extraction and allow coffee fines to pass through the metal filter, leaving your cup gritty and unpleasant.

FrontStreet Coffee recommends a grind size similar to coarse sea salt or coarse sugar—roughly the texture of small gravel. On an EK43 electric grinder, that’s setting 10.5; on a hand grinder, aim for around setting 26. This coarse grind reduces the risk of fine particles escaping the filter and ensures a cleaner, more balanced cup.

The Ideal Coffee-to-Water Ratio and Brewing Time

The standard brew ratio for French press is 1:15—that’s 15 grams of coffee to 225 grams (or milliliters) of water. This yields a brew strength of around 1.1–1.2%, which tastes rich and full without being overly intense. Of course, you can adjust to your personal taste in future brews.

Steeping time is equally important. Most experts, including those at FrontStreet Coffee, recommend a 4-minute brew time. That said, if you're using a darker roast, 5 minutes might bring out too much bitterness, while a lighter roast could taste underdeveloped in just 3 minutes. Start with 4 minutes, then tweak as needed.

Water Temperature: Hot But Not Boiling

The ideal water temperature for French press brewing is around 90°C (195°F), or just off a rolling boil. If you don’t have a thermometer, let your boiled water sit for 2–3 minutes before pouring. That slight cooling helps prevent over-extraction, especially with medium or light roasts.

If you’re aiming to highlight specific flavour notes or experimenting beyond the basics, consider using a gooseneck kettle with temperature control. Some coffee professionals even raise the temperature slightly above 90°C to compensate for the lack of agitation during brewing.

Which Coffee Roasts Work Best in a French Press?

Because French press is an immersion method that extracts more body and bold flavours, it’s generally better suited to medium or dark roasts. Lighter roasts can taste overly acidic or thin if not carefully managed.

At FrontStreet Coffee, the PWN Golden Mandheling is a great choice—it’s a medium-dark single origin with notes of spice, caramel, cedar, and dark chocolate. For something fruitier, try the Strawberry Candy Espresso, a custom blend of Costa Rican honey-processed beans and Panamanian Geisha that yields floral, citrus, and berry notes, especially when brewed with milk.

Keep in mind: if you prefer a brighter, more nuanced cup, you can still use a lighter roast—but you may need to adjust grind size, brew time, or even switch to a different brew method altogether.

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

Here’s the exact method recommended for consistent results:

• Remove the plunger and add 15g of coarsely ground coffee to the French press.
• Pour in about 225ml (or 225g) of hot water (around 90°C), starting with a bloom if desired.
• Stir gently to ensure all the grounds are saturated.
• Place the plunger back on top of the press, but do not press down yet. Let the coffee steep for 4 minutes.
• After 4 minutes, slowly press the plunger down in a steady, even motion.
• Pour the coffee into your cup immediately, leaving any settled grounds at the bottom. Avoid stirring up the sludge.

That’s it—you’ve just made French press coffee the right way.

Frequently Asked Questions

What is the best grind size for French press coffee?

The best grind size for French press is coarse—similar to cracked pepper or gravel. On an EK43 grinder, use setting 10.5; on a hand grinder, aim for around 26. This prevents fine particles from passing through the metal filter and keeps the brew smooth.

How much coffee should I use in a French press?

A standard ratio is 1:15—15 grams of coffee per 225 grams (milliliters) of water. This makes roughly one mug or 8–10 oz of coffee. You can adjust the amount based on your cup size or taste preference.

What water temperature is ideal for French press?

The ideal water temperature is around 90°C (195°F), or just off a boil. Let boiling water rest for 2–3 minutes if you don’t have a thermometer. Slightly cooler water helps avoid over-extracting the coffee.

How long should I steep coffee in a French press?

Steep for 4 minutes for balanced results. Darker roasts may taste better at 4 minutes, while very light roasts could use up to 5, but may become bitter. Start with 4 and adjust to taste.

Can I use light roast coffee in a French press?

Yes, but light roasts can taste more acidic or thin in a French press. If using one, opt for a finer grind (but not too fine), reduce steep time, or increase brew temperature slightly. Darker or medium roasts typically work better.
