What is a French Press?

A French Press, also known as a press pot or plunger pot, is a manual coffee brewing device. It consists of a cylindrical carafe, a plunger with a mesh filter, and a lid. The beauty of a French Press lies in its simplicity and the control it provides over the brewing process.

Why Use a French Press?

Before we delve into the intricacies of the grounds-to-water ratio, let’s quickly discuss the advantages of using a French Press.

Rich Brewing Experience

The French Press method allows the coffee grounds to steep in hot water for an extended period, resulting in a more robust and full-bodied flavor profile. This immersion brewing technique is preferred by many coffee enthusiasts who appreciate the richness and depth it brings to their cup of joe.

Unparalleled Control

Unlike other brewing methods, the French Press gives you complete control over the variables that affect the taste of your coffee. From water temperature and grind size to brewing time, every aspect can be fine-tuned to suit your personal preferences.

Simplicity and Portability

French Presses are incredibly easy to use and maintain. They don’t require any complicated setup or filters, making them perfect for brewing coffee in the comfort of your own home or while on the go. All you need is hot water and your favorite coffee grounds.

How to Determine the Ideal Number of Grounds

Now that we understand the beauty of French Press brewing, let’s explore how to determine the perfect number of grounds to use:

1. Grind Size Matters

The grind size of your coffee beans plays a crucial role in the extraction process. For French Press brewing, a coarse grind is ideal. The larger particles allow for better immersion and extraction, resulting in a bolder flavor. When measuring your coffee beans, ensure you have the right grind size for the best results.

2. The Golden Ratio

The golden ratio for French Press brewing is generally considered to be 1:15, coffee to water. This means that for every gram of coffee, you should use 15 grams of water. However, this ratio can be adjusted according to your personal taste preferences.

3. Determining the Total Brew Volume

Before we proceed, it’s essential to determine the total brew volume you desire. If you’re brewing for yourself, a standard French Press typically holds around 350ml (12 ounces) of water. If you’re brewing for more people, adjust the volume accordingly.


Let’s say you want to brew 350ml (12 ounces) of coffee using the golden ratio of 1:15. Multiply the desired brew volume by 15 to get the total grams of water needed. In this case, 350ml x 15 = 5250 grams of water.

4. Calculating the Coffee Weight

Now that we have the total grams of water, we can calculate the amount of coffee needed. Using the 1:15 ratio, divide the total grams of water by 15 to determine the grams of coffee required.

For a 350ml brew, divide 5250 grams by 15 to get 350 grams of coffee. This is the amount of grounds you should use for this specific brew.

Advantages of Using the Recommended Grounds

Following the recommended grounds-to-water ratio offers several advantages:


By using the suggested amount of coffee grounds, you ensure consistent results with each brew. This consistency allows you to fine-tune other variables and experiment with different beans without worrying about the dosage.

Optimal Extraction

The recommended ratio allows for optimal extraction of the coffee’s flavor compounds. Using too few grounds may result in a weak and diluted brew, while using too many can lead to an overpowering and bitter taste. The recommended amount strikes the perfect balance.


Following the recommended grounds-to-water ratio, you can maximize the number of cups brewed per bag of coffee. This cost-efficient approach ensures that you get the most out of your beloved beans without compromising on taste.

Difference between Under and Over Extraction

It’s crucial to differentiate between under and over extraction when brewing coffee. Understanding these concepts can help you further optimize your French Press brewing technique.

Under Extraction

Under extraction occurs when the coffee grounds are not adequately steeped, resulting in an underwhelming and weak cup of coffee. Signs of under extraction include a sour or acidic taste, lack of body, and muted flavors.

Over Extraction

On the other hand, over extraction happens when the coffee grounds are steeped for too long or when too many grounds are used. This leads to a bitter and astringent cup of coffee. Over-extracted coffee often tastes dry, with harsh and overwhelming flavors.

Tips for Achieving the Perfect Brew

To enhance your French Press brewing skills and achieve an exquisite cup of coffee, consider the following tips:

1. Invest in Freshly Roasted Beans

The quality of your coffee beans greatly impacts the final taste. Invest in freshly roasted beans to experience the full range of flavors and aromas your French Press can extract.

2. Preheat Your French Press

Preheating your French Press helps maintain a consistent brew temperature and prevents heat loss during the brewing process. Simply fill the carafe with hot water, let it sit for a minute, and then discard the water before starting the brewing process.

3. Use a Timer

Using a timer ensures consistency and precision. Keep track of your brewing time to achieve great results consistently.

4. Experiment and Adjust

Taste preferences can vary from person to person. Don’t be afraid to experiment with different grind sizes, ratios, and brewing times until you find your perfect cup of French Press coffee.

5. Cleanliness Matters

Regularly clean your French Press to avoid any buildup of coffee oils or residue, which can negatively impact the flavor of your brew. Disassemble the components and wash them thoroughly after each use.


In conclusion, determining the perfect number of grounds for your French Press is a combination of science and art. By considering the grind size, ratios, and total brew volume, you can achieve a consistently exquisite cup of coffee.

Remember to experiment, embrace the process, and most importantly, enjoy every sip of your meticulously brewed French Press coffee!

FAQs (Frequently Asked Questions)

1. What is the ideal coffee-to-water ratio for French press?

The ideal coffee-to-water ratio for French press is generally considered to be 1:15, which means one part of coffee for every 15 parts of water. This ratio can be adjusted based on personal preference, but this is a good starting point for a balanced and flavorful cup of French press coffee.

2. How many grounds should I use for a single serving of French press?

For a single serving of French press coffee, you can use around 1 to 2 tablespoons of coffee grounds. This amount may vary depending on your taste preferences, the size of your French press, and the intensity of flavor you desire. It is recommended to experiment and adjust the amount of coffee grounds to suit your personal taste.

3. Can I use pre-ground coffee for French press?

Yes, you can use pre-ground coffee for French press. However, the flavor and aroma of freshly ground coffee beans are usually more intense and satisfying compared to pre-ground coffee. If using pre-ground coffee, make sure it is coarse to achieve the best results in the French press.

4. How long should I let the coffee steep in the French press?

The recommended steeping time for French press coffee is around 4 to 5 minutes. This allows the coffee grounds to fully extract their flavor and oils into the water. However, steeping time can be adjusted based on personal preference. Longer steeping times can result in a stronger and more robust flavor, while shorter steeping times may produce a milder taste.

5. Can I reuse the coffee grounds for a second brew in the French press?

While it is technically possible to reuse coffee grounds for a second brew in the French press, the resulting cup of coffee will be significantly weaker in flavor and may lack the same richness as the first brew. It is generally recommended to use fresh coffee grounds for each brew to enjoy the best taste and aroma. Reusing coffee grounds may also lead to over-extraction and bitterness in the subsequent brew.
