The French press is one of the simplest and most popular methods for brewing coffee. With its prolonged contact between coffee and water, it produces a strong, rich brew with a full-bodied texture, thanks to its relatively coarse filter. Here’s a guide to perfecting your French press coffee.
Grind Size and Coffee Dosage
For a French press, a medium to coarse grind is ideal. Using a finer grind will result in a more intense flavor due to increased extraction, but a coarser grind helps prevent over-extraction, which can make the coffee taste bitter.
As for the coffee-to-water ratio, aim for 30 grams of coffee per 250 ml of water (roughly 1 ounce per 8 fluid ounces). For a standard 1-liter (34-ounce) French press, you’ll need about 60 grams (2 ounces) of coffee beans.
Pro tip: Avoid measuring coffee by eye. Even slight changes in the ratio can significantly affect the taste. For consistent results, use a scale to weigh your coffee beans before each brew.
Water Temperature
The optimal water temperature for brewing French press coffee is 92-95°C (197-203°F). To achieve this, bring the water to a boil and let it cool for about 30 seconds. If you have a thermometer, you can measure the water temperature more precisely, which helps ensure consistency in your brew.
Brewing Process
- Pour a little hot water into the French press to warm it up, then discard the water. This helps maintain the ideal brewing temperature for better extraction.
- Measure out the coffee (30 grams for every 250 ml of water) and pour it into the French press.
- Slowly pour the hot water over the grounds, ensuring all the coffee is evenly saturated. Stir gently to make sure the grounds are fully mixed with the water.
- Place the lid on the French press without pressing down the plunger. This keeps the heat in during brewing.
- Let the coffee brew for 4 minutes. If you prefer a stronger cup, you can extend the brewing time to 5 minutes, but 4 minutes is generally a good balance for most tastes.
- After the brewing time is up, gently press the plunger down. Make sure to do this slowly to avoid agitation, which can lead to over-extraction and bitterness. Once the plunger is down, immediately pour the coffee into a serving pot or cups.
Important: Don’t leave the coffee sitting in the French press, as it will continue to extract, making the brew too bitter.
Additional Tips
- If you like your coffee stronger or weaker, feel free to adjust the coffee-to-water ratio. Experimenting with different ratios will help you find the perfect balance for your taste.
- For the freshest flavor, grind your coffee beans just before brewing. A consistent grind size is key to even extraction.
- When pouring water over the grounds, do so slowly and in a circular motion to ensure all the coffee is evenly soaked.
- After each use, thoroughly clean the French press—especially the filter and carafe—to remove old coffee oils that can affect the flavor of future brews.
