In “The Perfect Coffee-to-Water Ratio,” James Hoffmann explores the world of coffee brewing ratios and recipes. He explains the benefits of using grams per liter as a more accurate measurement and suggests a popular ratio of 1:15 for determining the amount of ground coffee needed. Hoffmann stresses the importance of extraction in determining the strength of the coffee and encourages experimentation with finer grinds or longer steeping times before adjusting the ratio. He also discusses how different brewing methods may require different ratios, with infusion methods typically needing more coffee than percolation methods. Overall, this informative video provides valuable insights into finding the right coffee-to-water ratio to achieve the perfect cup of joe.


When it comes to brewing a delicious cup of coffee, getting the coffee-to-water ratio right is essential. The ratio refers to the amount of coffee grounds you use in relation to the amount of water you use. It determines the strength and taste of your coffee and can make or break your brewing experience. In this article, we will explore the importance of the coffee-to-water ratio, the use of grams per liter for accuracy, popular ratios, the role of extraction, different ratios for brewing methods, consistency in measuring, factors affecting the ratio, and adjusting the ratio for desired strength.

Importance of Coffee-to-Water Ratio

Definition of coffee-to-water ratio

The coffee-to-water ratio is the proportionate amount of coffee grounds to water used in brewing coffee. It is typically expressed as a ratio, such as 1:15, which means one part coffee grounds to fifteen parts water.

Impact on the taste and strength of coffee

The coffee-to-water ratio plays a crucial role in determining the taste and strength of your coffee. A higher ratio will result in a stronger and more flavorful cup, while a lower ratio will yield a milder taste. Finding the right ratio for your desired brewing preferences is key to achieving the perfect cup of coffee.

Using Grams per Liter for Accuracy

Advantages over scoops or volumetric measurements

Using grams per liter as a measurement for the coffee-to-water ratio offers several advantages over scoops or volumetric measurements. Unlike scoops, which can vary in size and weight, grams per liter provides a more accurate and consistent measurement. This is particularly important when it comes to achieving consistent results in your brewing.

Recommended measurement for consistent results

To ensure consistency in your coffee brewing, it is highly recommended to use grams per liter as the measurement for your coffee-to-water ratio. This will allow you to precisely measure the amount of coffee and water used, leading to consistent and reliable results every time you brew.

Popular Coffee-to-Water Ratio

Explanation of ratio: 1:15

One of the most popular coffee-to-water ratios is 1:15. This means using one part coffee grounds to fifteen parts water. This ratio is a good starting point for most people and produces a well-balanced and flavorful cup of coffee. However, it is important to note that the ideal ratio may vary depending on personal preference and the brewing method used.

Determining the amount of ground coffee needed

To determine the amount of ground coffee needed for a desired amount of brewed coffee, you can use the 1:15 ratio as a guide. For example, if you want to brew 500 ml of coffee, you would divide 500 by 15 to get the amount of coffee grounds needed. In this case, it would be approximately 33 grams of coffee.

Importance of Extraction

Role of extraction in coffee strength

Extraction refers to the process of dissolving the coffee’s soluble compounds from the grounds into the water during brewing. It plays a crucial role in determining the strength of your coffee. Over-extraction can result in a bitter and unpleasant taste, while under-extraction can lead to a weak and lackluster cup. Finding the right balance is key to achieving the desired strength of your coffee.

Experimenting with grind size and steeping time

To achieve the perfect extraction, it is often necessary to experiment with factors such as grind size and steeping time. Finer grinds generally result in a faster extraction, while coarser grinds require a longer steeping time. By adjusting these variables, you can fine-tune the extraction process and achieve the ideal strength and taste for your coffee.

Different Ratios for Brewing Methods

Percolation methods

Percolation methods, such as pour-over and drip brewing, involve water passing through a bed of coffee grounds. For these methods, a coffee-to-water ratio of around 1:15 is commonly used. The water does not remain in contact with the grounds for an extended period, so using a slightly lower ratio ensures a balanced extraction.

Infusion methods

Infusion methods, such as French press and AeroPress, involve coffee grounds and water being in contact for a longer duration. These methods typically require a higher coffee-to-water ratio, around 1:17 or even 1:20, to compensate for the extended steeping time.

Consistency in Measuring

Using a scale for accurate measurements

To maintain consistency in your brewing, it is essential to use a scale for accurate measurements. Measuring the amount of coffee and water by weight instead of volume ensures precision and eliminates variables caused by variations in the density of coffee grounds. This allows for more consistent and reproducible results.

Impact on consistent brewing

Consistency in measuring the coffee-to-water ratio directly affects the consistency of your brewing. By using a scale and following the recommended ratio, you eliminate the guesswork and can reproduce your preferred cup of coffee consistently. It also allows you to make informed adjustments to the ratio if desired.

Factors Affecting Coffee-to-Water Ratio

Coffee roast level

The roast level of the coffee beans can affect the ideal coffee-to-water ratio. Darker roasts tend to have a more pronounced flavor, so a slightly higher ratio, closer to 1:16, could be used to balance the intensity. Lighter roasts, on the other hand, may require a lower ratio to prevent over-extraction and maintain the delicate flavors.

Coffee bean origin

The origin of the coffee beans can also impact the optimal coffee-to-water ratio. Different regions produce beans with distinct characteristics, such as acidity and flavor profiles. Adjusting the ratio based on the origin can help highlight or balance these unique qualities and enhance the overall taste experience.

Personal preference

Ultimately, personal preference plays a significant role in determining the ideal coffee-to-water ratio. Some individuals prefer a stronger and more robust brew, while others enjoy a milder cup. Experimenting with different ratios and finding the perfect balance that suits your taste buds is key to enjoying your coffee to the fullest.

Adjusting the Ratio for Desired Strength

Increasing or decreasing coffee amount

If you find that your coffee is too weak or too strong for your liking, it is possible to adjust the coffee-to-water ratio to achieve your desired strength. Increasing the amount of coffee grounds will result in a stronger cup, while decreasing the amount will yield a milder taste. It is important to make gradual adjustments and taste-test along the way to find the perfect balance.

Finding the perfect balance

Finding the perfect balance in your coffee-to-water ratio requires experimentation and fine-tuning. By gradually adjusting the amount of coffee and water used and carefully observing the taste and strength of your brew, you can discover the ideal ratio that suits your personal preferences. Remember to keep track of your adjustments to maintain consistency in your future brews.

The coffee-to-water ratio is a fundamental aspect of coffee brewing that significantly impacts the taste and strength of your cup. Using grams per liter as a measurement provides accuracy and consistency in your brewing. A ratio of 1:15 is a popular starting point, but personal preference, extraction, and brewing methods may require adjustments. Consistency in measuring, factors such as coffee roast level and origin, and fine-tuning the ratio to achieve your desired strength are all part of the journey to brewing the perfect cup of coffee. So, grab your scale, experiment, and enjoy the art of coffee brewing!
