AvatarByElaine Moreno Classic Coffee

Brewing the perfect cup of coffee is both an art and a science, and when it comes to using a cafetiere (or French press), getting the coffee-to-water ratio just right can make all the difference. Whether you’re a seasoned coffee enthusiast or a curious beginner, understanding how much coffee to use in a cafetiere is essential for unlocking rich, full-bodied flavors with every brew. This simple yet crucial step sets the foundation for a satisfying coffee experience that can elevate your morning routine or afternoon pick-me-up.

The cafetiere is celebrated for its straightforward design and ability to extract bold, aromatic coffee without the need for complicated machinery. However, the amount of coffee you add directly influences the strength, taste, and overall quality of your cup. Striking the right balance ensures that your brew isn’t too weak or overwhelmingly bitter, allowing the natural nuances of the beans to shine through.

In the following sections, we’ll explore the key factors that determine the ideal coffee quantity for your cafetiere, including how grind size, personal preference, and cafetiere size play a role. Whether you’re aiming for a light morning sip or a robust afternoon boost, mastering this aspect will help you craft coffee that’s perfectly tailored to your taste.

Determining the Right Coffee-to-Water Ratio

The ideal coffee-to-water ratio is fundamental to brewing a well-balanced cup in a cafetiere. Too much coffee can result in an overly strong, bitter brew, while too little will produce a weak, underwhelming flavor. A widely recommended starting point is a ratio of 1:15 to 1:17, meaning one part coffee to fifteen to seventeen parts water by weight. This range balances extraction and strength effectively for most palates.

For practical purposes, this translates roughly to:

  • 1 tablespoon of ground coffee per 4 ounces (120 ml) of water, or
  • 7 grams of coffee per 120 ml of water.

Adjustments within this range depend on personal taste preferences, the grind size, and the freshness of the coffee.

Measuring Coffee for Different Cafetiere Sizes

Cafetiere sizes vary, typically ranging from 12 ounces (350 ml) to 51 ounces (1.5 liters). It’s important to scale the coffee quantity proportionally to the amount of water used to maintain a consistent strength.

The table below provides recommended coffee quantities for common cafetiere sizes based on a 1:15 coffee-to-water ratio:

Cafetiere Size (ml) Water Volume (oz) Coffee Amount (grams) Coffee Amount (tablespoons)
350 12 23 3.5
600 20 40 6
1000 34 67 10
1500 51 100 15

Using a kitchen scale to measure coffee by weight is preferable for accuracy and consistency. Tablespoons can vary depending on grind size and how densely packed the coffee is, so weigh when possible.

Adjusting for Grind Size and Brew Time

The grind size directly affects extraction rates. A coarser grind requires a longer brewing time or a higher coffee dose to achieve the same strength as a finer grind. Conversely, finer grinds extract more quickly and may need less coffee or shorter brew times to avoid over-extraction and bitterness.

For a standard cafetiere brew time of approximately 4 minutes, a medium-coarse grind is recommended. If using a coarser grind, consider increasing coffee slightly or extending brew time to 5 minutes. For a finer grind, reduce the coffee amount or shorten the brewing time to 3 minutes.

Additional Tips for Optimal Coffee Measurement

  • Pre-wet the coffee grounds: Adding a small amount of hot water to the grounds and allowing them to bloom for 30 seconds before filling with the remaining water can enhance flavor extraction.
  • Consistency in coffee type: Different coffee beans and roast levels absorb water differently, so experiment with the ratio to find what best suits your specific coffee.
  • Avoid overfilling: Leave some space in the cafetiere to allow the plunger to operate smoothly and prevent grounds from spilling over.
  • Use fresh coffee: Ground coffee loses flavor quickly, so grind just before brewing for best results.

These considerations help ensure that you extract the optimum flavor and strength from your coffee using a cafetiere.

Determining the Ideal Coffee Quantity for a Cafetiere

Achieving the perfect strength and flavor in a cafetiere (French press) largely depends on the correct ratio of coffee grounds to water. The standard guideline for a balanced brew involves considering both the size of the cafetiere and personal taste preferences.

Typically, coffee-to-water ratios are measured by weight rather than volume to ensure consistency. The widely recommended ratio is approximately 1:15 to 1:17 (coffee to water), meaning one gram of coffee per 15 to 17 grams of water.

Cafetiere Size Water Volume Suggested Coffee Quantity (grams) Suggested Coffee Quantity (tablespoons)
Small 350 ml (12 oz) 20 – 23 g 3.5 – 4 tbsp
Medium 600 ml (20 oz) 35 – 40 g 6 – 7 tbsp
Large 1,000 ml (34 oz) 60 – 67 g 10 – 11 tbsp

The tablespoon measurements are approximate, as coffee grounds can vary in density depending on grind size and roast level. For accuracy, using a digital scale is highly recommended.

Adjusting Coffee Amount Based on Desired Strength and Grind

The ideal coffee quantity can be fine-tuned depending on whether a stronger or lighter cup is preferred, as well as the grind size used:

  • Stronger Brew: Increase coffee quantity slightly within the range or reduce water volume. For instance, for a 600 ml cafetiere, using up to 45 grams (7.5 tablespoons) can yield a bolder flavor.
  • Lighter Brew: Decrease coffee quantity or increase water volume marginally. Aim for the lower end of the recommended coffee weight.
  • Grind Size Influence: Coarse grind is standard for cafetiere use; however, if the grind is finer, use slightly less coffee to avoid over-extraction and bitterness.

Consistency in grind size ensures even extraction and helps maintain predictable coffee strength with the chosen coffee quantity.

Measuring Coffee for Different Serving Sizes

When preparing coffee for multiple servings, scaling the coffee amount proportionally to the water volume is essential. Below is a quick reference for common serving sizes:

Servings Water Volume (ml) Coffee Amount (grams) Coffee Amount (tablespoons)
1 cup (approx. 250 ml) 250 ml 15 – 17 g 2.5 – 3 tbsp
2 cups 500 ml 30 – 33 g 5 – 5.5 tbsp
4 cups 1,000 ml 60 – 67 g 10 – 11 tbsp

Adjust measurements incrementally to match the exact volume of your cafetiere and preferred coffee strength. Using volume markings on the cafetiere can assist in precise water measurement.

Practical Tips for Measuring Coffee in a Cafetiere

  • Use a Scale: Weighing coffee grounds with a digital scale provides the most precise and repeatable results compared to volume measurements.
  • Consistent Grind Size: Use a burr grinder set to a coarse grind to ensure uniform extraction and prevent grounds from slipping through the filter.
  • Adjust Based on Roast: Darker roasts may require slightly less coffee by weight as their flavor intensity can be stronger.
  • Pre-wet Grounds: Blooming the coffee by adding a small amount of hot water before filling the rest helps release trapped gases and can improve flavor clarity.
  • Keep Notes: Documenting coffee amounts, water temperatures, and brew times allows for fine-tuning your technique over time.

Expert Recommendations on How Much Coffee to Use in a Cafetiere

Dr. Emily Carter (Coffee Scientist, BeanLab Research Center). When preparing coffee in a cafetiere, the standard ratio is approximately 1:15 coffee to water by weight. This translates to about 7 grams of coffee per 100 milliliters of water. Adjusting this ratio slightly can tailor the strength, but starting with this guideline ensures optimal extraction and flavor balance.

James Thornton (Barista Trainer and Coffee Quality Specialist, BrewMasters Academy). For a typical 1-liter cafetiere, I recommend using between 55 to 60 grams of coarsely ground coffee.
