What is a French Press?

A French press, also known as a press pot or plunger pot, is a classic coffee brewing device that produces a rich and full-bodied cup of coffee. It consists of a glass or metal cylindrical container with a plunger and a mesh filter attached to it. The beauty of a French press lies in its simplicity and ability to extract maximum flavor from coffee grounds.

Why Choose a French Press?

There are several reasons why coffee enthusiasts opt for the French press brewing method:

  • Full Flavor: French press brewing allows the natural oils and flavors of the coffee beans to be retained, resulting in a robust and aromatic cup of coffee.
  • Control: You have control over the brewing process, from the water temperature to the steeping time, allowing you to customize your cup of coffee according to your preferences.
  • Simplicity: French press brewing is a straightforward method that does not require any fancy equipment or filters, making it accessible to anyone.

How to Brew Coffee in a French Press

Now that we understand the basics, let’s dive into the step-by-step process of brewing coffee in a French press:

Step 1: Measure the Coffee

The first step to brewing a perfect cup of coffee is to measure the coffee grounds accurately. For a 13.5 oz French press, we recommend using a coffee-to-water ratio of 1:15. This means for every gram of coffee, you’ll need 15 grams of water. Depending on your preference, adjust the amount of coffee accordingly.

Step 2: Grind the Coffee

For optimal extraction, it is crucial to grind the coffee beans just before brewing. Aim for a coarse grind size, similar to breadcrumbs. Using a burr grinder will ensure a consistent grind size, resulting in a balanced flavor profile.

Step 3: Heat the Water

While the water is heating, preheat your French press by pouring hot water into it and letting it sit for a minute. This helps maintain the brewing temperature throughout the process. Heat the water to around 200°F (93°C), just below boiling point.

Step 4: Blooming the Coffee

Pour a small amount of hot water (twice the weight of coffee) over the grounds to saturate them. This step is called blooming and allows the coffee to degas, resulting in enhanced flavors and aromas. Let it bloom for 30 seconds.

Step 5: Pour the Remaining Water

Gently pour the remaining hot water into the French press, ensuring all the coffee grounds are fully submerged. Give it a gentle stir with a spoon to ensure even extraction.

Step 6: Steep

Place the plunger lid on top of the French press but do not press it down. Let the coffee steep for about four minutes. This steeping time can be adjusted based on your taste preferences. Longer steeping times result in a stronger and more intense flavor.

Step 7: Plunge and Pour

After the desired steeping time, slowly press the plunger down to separate the coffee grounds from the liquid. Once fully pressed, pour the brewed coffee into your cup and enjoy!

How Much Coffee to Use for a 13.5 oz French Press: Tips and Tricks

Tip 1: Experiment with Coffee-to-Water Ratio

The recommended coffee-to-water ratio of 1:15 is a good starting point, but feel free to adjust it based on your taste preferences. You can increase or decrease the amount of coffee to make your cup stronger or milder.

Tip 2: Use Freshly Roasted Beans

To ensure the best flavor, use freshly roasted coffee beans. The flavors and aromas are at their peak within a couple of weeks of roasting. Purchase whole beans and grind them just before brewing for maximum freshness.

Tip 3: Maintain the Right Water Temperature

The water temperature plays a crucial role in coffee extraction. If the water is too hot, it can result in a bitter taste, while water that is too cold will under-extract the coffee. Aim for 200°F (93°C) for optimal results.

Tip 4: Invest in a Quality French Press

Not all French presses are created equal. Invest in a high-quality press with a sturdy plunger and a fine-mesh filter. This will prevent grounds from seeping into your cup and ensure a smoother coffee experience.

Tip 5: Experiment with Brew Time

The steeping time can be adjusted to suit your taste preferences. If you prefer a milder cup, shorten the steeping time, and if you prefer a bolder cup, lengthen the steeping time. Keep a note of the times that yield your desired flavor profile.

Advantages and Disadvantages of French Press Brewing


French press brewing offers several advantages:

  • Rich and Full-Bodied Flavor: The full immersion brewing method and the metal mesh filter allow for maximum extraction of flavors, resulting in a rich and full-bodied cup of coffee.
  • Control: You have control over various brewing parameters, allowing you to customize your coffee according to your preferences.
  • Portability: French presses are relatively portable, making them an excellent choice for camping or travel.


Despite its many advantages, the French press brewing method does have a few limitations:

  • Sediment: Some fine coffee grounds may find their way into the final cup, causing a slightly gritty texture.
  • Time-Sensitive: French press brewing requires careful attention to time to achieve optimal results. Steeping for too long or too short can significantly impact the flavor profile.
  • Cleaning: Cleaning a French press can be slightly time-consuming due to the need to properly disassemble and wash the plunger and filter.
