How the Cup Coffee 2-9 Method Works
The key to success with the Cup Coffee 2-9 method is to maintain the correct ratio of coffee grounds to water. This ratio ensures that the water can effectively extract the desired flavors from the coffee grounds.
Here are the basic steps involved in brewing coffee using the Cup Coffee 2-9 method:
- Grind the Coffee: Choose your preferred coffee beans and grind them to a medium-fine consistency. This grind size ensures that the water can pass through the coffee grounds quickly enough for optimal extraction.
- Measure the Coffee Grounds: Using a kitchen scale, measure out 2 grams of coffee grounds.
- Measure the Water: Measure out 9 grams of hot water (ideally between 195-205°F).
- Pour the Water Over the Coffee Grounds: Pour the hot water slowly and evenly over the coffee grounds. It’s best to pour in a circular motion to ensure that all the coffee grounds are evenly saturated.
- Steep the Coffee: Allow the coffee to steep for 3-4 minutes. This allows the water to fully extract the flavors from the coffee grounds.
- Enjoy! After the brewing process is complete, carefully decant the coffee into your preferred cup and enjoy.
The Science Behind the Cup Coffee 2-9 Ratio
“Why 2 grams of coffee to 9 grams of water?” you might ask. It’s not arbitrary! The Cup Coffee 2-9 ratio is based on the principles of coffee extraction and solubility. This precise ratio ensures that the water can effectively extract the desired compounds from the coffee grounds without over-extracting the bitter compounds.
The Role of Extraction
Extraction is the process by which the water dissolves the soluble compounds from the coffee grounds, which are responsible for its flavor, aroma, and caffeine. The Cup Coffee 2-9 ratio ensures that the water is able to extract these compounds effectively without leaving any of the grounds undissolved.
The Solubility of Coffee Compounds
Different coffee compounds have different solubility levels. For example, caffeine is highly soluble, while some bitter compounds are less soluble. The Cup Coffee 2-9 ratio provides an optimal environment for the extraction of desirable compounds while limiting the extraction of unwanted compounds.
