If you’re passionate about coffee and curious about manual brewing techniques, the French press is a method that offers both simplicity and depth. As a full immersion brewing technique, it maximizes coffee extraction by ensuring that water is in constant contact with the grounds. In this guide, we’ll delve into every detail—from understanding the coffee-to-water ratio to the importance of optimal extraction—so you can enjoy a rich, well-balanced cup of coffee every time.
Essential Equipment and Their Benefits
For truly great French press coffee, the right equipment is key. Not only do these tools enhance the brewing process, but they also contribute to consistent grind consistency and optimal extraction:
Scale: Accurate measurements are essential. A scale guarantees the correct coffee-to-water ratio, often starting around 15:1
French Press: The core tool for full immersion brewing that allows you to control every aspect of extraction.
Fresh Whole Bean Coffee: Using high-quality beans ensures a more vibrant flavor profile.
Burr Grinder: For a uniform, coarse grind that prevents over-extraction and bitterness.
Kettle: A temperature-controlled kettle is ideal; if unavailable, boil water and let it rest for 30 seconds to reach the desired 195–205°F range.
Scale: Accurate measurements are essential. A scale guarantees the correct coffee-to-water ratio, often starting around 15:1.
Timer: Precision in brewing time is critical for balanced flavor.
How To Make Coffee using a French Press
1. Preheat the French Press
Begin by preheating your French press to stabilize the brewing temperature. Simply add hot water, swirl it around to warm the vessel, and then discard the water. This simple step supports proper temperature management and optimal extraction.
2. Weigh Out Your Coffee
Measure your coffee and water using a ratio of 15:1. For example, use 20 grams of coffee for 300 grams of water. This step is essential to ensure that you achieve the perfect balance between strength and flavor. Using precise measurements leads to better consistency and superior extraction.
3. Grind Your Coffee
Set your burr grinder to a coarse setting. A consistent, coarse grind is crucial because it helps avoid over-extraction, resulting in a smoother cup. Grinding just before brewing also preserves the coffee’s natural aroma and flavor compounds.
4. Measure and Heat Water
Heat your water to between 195°F and 205°F, or let it rest for 30 seconds after boiling if you lack a temperature gauge. This temperature range is optimal for releasing the rich, full-bodied flavors from your coffee grounds without burning them.
5. Tare Your Scale and Begin the Process
Place your French press on the scale and tare it to zero. Add your freshly ground coffee, verify the weight, and tare the scale again. This meticulous process is key to maintaining the ideal coffee-to-water ratio, ensuring balanced extraction and a consistent brew.
6. The Bloom and Water Addition
Start your timer as you pour 60 grams of hot water over the coffee. This initial pour is known as “the bloom” and helps release carbon dioxide from the coffee grounds, which enhances flavor extraction. Allow the bloom to settle for 30 seconds before adding the remaining water until you reach 300 grams.
7. Brewing and Immersion
After adding all the water, place the plunger on your French press—but do not press it down immediately. Let the coffee brew undisturbed for 4 minutes. This period of full immersion is what allows the water to extract the coffee’s rich oils and nuanced flavors effectively.
8. Plunging with Care
At the end of the brewing time, slowly and gently press the plunger. Apply steady pressure to separate the grounds from the brewed coffee. A controlled plunge helps prevent sediment from passing through, ensuring a cleaner cup.
9. Decant and Enjoy
Once you’ve plunged, immediately decant your coffee into another container or your favorite mug. This step prevents the coffee from continuing to brew and becoming overly strong, preserving the intended flavor profile.

How to Clean A French Press
A clean French press is essential for optimal coffee flavor. Start by disassembling the press—remove the plunger and rinse the carafe with warm water to dislodge any lingering coffee grounds. If necessary, use a gentle dish soap with warm water and a soft brush to remove any oil residues. Rinse thoroughly and dry with a soft cloth. A well-maintained French press will consistently deliver high-quality coffee and prevent old oils from affecting the taste.
Final Thoughts
Brewing coffee with a French press is as much an art as it is a science. By understanding the nuances of full immersion brewing, maintaining an optimal coffee-to-water ratio, and using the proper equipment, you can consistently achieve a cup of coffee that is both robust and refined. Embrace these detailed techniques, and let every cup be a step toward mastering the rich world of manual coffee brewing. Experiment with slight adjustments to your process, and enjoy the journey toward coffee brewing mastery.
