Coffee Brewing Ratio: The Key Factor

Embarking on the journey into specialty coffee, the most significant leap towards enhancing flavor is to acquire a good set of barista scales and begin measuring your coffee. While some may view this as excessive, the impact it has is substantial. As you delve into the world of weights and brewing ratios, the old ways of using scoops and approximations will quickly become a thing of the past!

Understanding Coffee-to-Water Ratios

In the realm of coffee, achieving the ideal coffee-to-water ratio plays a pivotal role in crafting an outstanding brew. Whether you're a coffee enthusiast in Big Lake, MN, or have a penchant for air roasting in Minnesota, grasping this ratio is vital to unlock the full potential of your coffee.

What Is A Coffee-To-Water Ratio?

Simply put, a coffee-to-water ratio is the measurement of how much coffee is required for the volume of water you intend to use for brewing, or vice versa. 

This ratio varies depending on the brewing technique you employ and your preferred coffee strength. While the latter is a matter of personal taste, the former involves intriguing scientific considerations.

The Science Behind TDS in Coffee

The art of coffee brewing involves an extraction process. When hot water interacts with coffee grounds, it extracts the flavors embedded in the beans. This flavor-rich liquid becomes our beloved coffee. However, not every part of the coffee bean contributes to the flavor, which is why monitoring and controlling the extraction process is crucial.

The benchmark for this control is often expressed as a standard percentage of dissolved solids in the water – TDS (total dissolved solids) quantifies the extent to which coffee compounds have dissolved in our brewing water. Extract too much, and your coffee turns heavy and bitter; extract too little, and it becomes insipid and sour.

Achieving the Optimal TDS%

Each brewing method, including its precise measurements and timings, has been thoroughly studied by coffee professionals and is recognized as the most effective way to attain the ideal TDS and, consequently, flavor.

The primary variables in these recipes include:

  • The coffee-to-water ratio.
  • The duration of coffee-water contact.
  • The brewing pressure applied.

When one of these factors changes, adjustments to the other two are necessary to maintain the superior taste of coffee.

Let’s examine two vastly different brewing methods: the French press and espresso. 

Comparing Brewing Ratios Across Methods

Espresso, renowned for its intense flavor, operates under high pressure (9 bars) and has minimal contact time between coffee and water—hence, it demands a relatively high coffee-to-water ratio for achieving the desired flavor. Typically, espresso employs a 1:2 ratio, meaning if you use 18g of coffee, you can expect an output of 36g of espresso—a preference cherished by many Minnesota coffee roasters.

In contrast, preparing French press coffee involves minimal pressure and extended brewing time in minutes, allowing water to thoroughly extract the rich flavors from the ground beans. Consequently, the coffee-to-water ratio adjusts to accommodate these factors. The accepted range for the coffee-to-water ratio in a French press can vary from 1:12 to 1:18, catering to diverse taste preferences. This implies that you'll brew approximately 15g of coffee in roughly 225g of water per person.

Once you embrace the use of brewing ratios, your home coffee endeavors will experience an instant enhancement, with minimal effort required to significantly elevate the flavor.

Exploring Brewing Ratios for Various Methods

Now, let's delve into how brewing ratios differ among various methods, from traditional drip coffee to the trendy espresso:

  • Espresso: Espresso, celebrated for its boldness, typically adheres to a 1:2 ratio (coffee to water). In simpler terms, using 18g of coffee yields 36g of espresso, making it a favored choice among Minnesota coffee roasters.
  • Manual Pour Over: For those who savor a more delicate brew, the ratio hovers around 1:16, allowing for a balanced and nuanced flavor profile.
  • French Press: Due to its extended extraction time, French press coffee adopts ratios ranging from 1:12 to 1:17, catering to diverse taste preferences.
  • Moka Pot: This stovetop classic thrives with a ratio of roughly 1:10, delivering a rich and concentrated coffee experience.
  • Aeropress: The versatile Aeropress offers flexibility, with ratios spanning from 1:6 to 1:12, accommodating both bold and milder brews.

Embracing Precision - Measuring with Grams

Consistency holds the key to successful coffee brewing, underscoring the significance of precision. Incorporating a dependable coffee scale into your brewing routine becomes imperative. In this context, grams, not casual scoops, become the standard unit of measurement, particularly for Minnesota air roasting enthusiasts on a quest for the perfect cup.

These scales are meticulously designed to withstand the rigorous demands of coffee preparation, ensuring precision and enabling meticulous adjustments to brewing ratios.

Whether you're situated in Big Lake, MN, or any corner of the world, mastering the coffee-to-water ratio embarks you on a journey toward exceptional coffee experiences. Embrace the amalgamation of art and science in brewing, and you'll relish every cup from your preferred Minnesota coffee roaster.
