Heating the Water
To begin, boil water in a kettle and let it rest for 30 seconds to cool slightly, reaching approximately 205°F․ This temperature is ideal for brewing coffee, as it extracts flavors without burning the beans․ Use fresh, filtered water to ensure the best taste․ Pouring water that’s too hot can lead to over-extraction, while water that’s too cold may result in under-extraction․ Properly heated water is the foundation of a balanced and flavorful Chemex brew․
Preparing the Chemex Filter
Place a Chemex filter in the brewer, ensuring the three-fold side aligns with the spout․ Carefully rinse the filter with hot water to remove any paper taste and preheat the glass․ Discard the rinse water, and the filter will adhere to the walls of the Chemex․ This step ensures a clean, balanced extraction and prevents any unwanted flavors from affecting your brew․ Proper preparation of the filter is essential for achieving the signature Chemex coffee quality․
Adding Coffee Grounds
Measure 42g (about 6 tablespoons) of coffee and grind it to a medium-coarse texture, similar to kosher salt․ Place the grounds evenly in the center of the prepared Chemex filter, ensuring the surface is flat․ This step is crucial for balanced extraction․ Gently shake the brewer to level the grounds, creating an even surface․ Avoid overfilling, as this can lead to uneven extraction․ Once the coffee is added, you’re ready to proceed to the blooming phase of the brewing process․
Blooming the Coffee
Pour approximately 50g of hot water (just off the boil) evenly over the coffee grounds to saturate them․ Allow the coffee to bloom for 30 seconds․ This step releases trapped gases and ensures even extraction․ Use a circular motion to pour, starting from the center and moving outward․ After blooming, the coffee should have expanded slightly․ Once the bloom period ends, you’re ready to proceed with pouring the remaining water in stages to complete the brewing process․
Pouring the Rest of the Water
After the bloom, slowly pour the remaining water in a circular motion, starting from the center and moving outward․ Aim for a total of approximately 400-450g of water, depending on your ratio․ Pour in stages, ensuring all grounds are saturated but not flooded․ Maintain a steady stream to avoid channeling․ The water level should drop evenly, and the coffee bed should remain flat․ Complete this step within 2-3 minutes to achieve optimal extraction and a balanced brew․
Serving the Brew
Once the brewing process is complete, carefully remove the filter and grounds from the Chemex․ Pour the freshly brewed coffee directly into your cup(s)․ The Chemex is designed with a spout for easy, mess-free serving․ Serve immediately to enjoy the coffee at its optimal flavor and temperature․ For a standard 6-cup Chemex, expect 3-4 servings․ You can add milk, sugar, or other desired toppings to enhance your coffee experience, but many prefer it black to savor the pure, clean flavor․
Tips for the Perfect Chemex Brew
Use fresh, high-quality coffee beans for optimal flavor․ Ensure all equipment is clean to avoid residual tastes․ Experiment with ratios and grind sizes to suit your taste preferences․
Coffee-to-Water Ratio
The ideal coffee-to-water ratio for a Chemex is typically 1:11 to 1:16․ For a standard 8-cup Chemex, use about 42-50 grams of coffee․ Adjust the ratio to suit your taste preferences—stronger brews may prefer a 1:10 ratio, while lighter flavors lean toward 1:15․ Precision ensures balance, allowing the coffee’s nuances to shine without under or over-extraction․ Consistency in this ratio is key to achieving a perfect brew every time․
Importance of Grind Size
Grind size plays a crucial role in achieving a balanced Chemex brew․ Opt for a medium to medium-coarse grind, similar to kosher salt, to ensure proper water flow and extraction․ A grind that’s too fine can lead to over-extraction and bitterness, while too coarse may result in under-extraction and a weak cup․ Consistent grind size ensures even saturation, allowing the coffee’s full flavor potential to shine through․ Adjusting the grind can fine-tune your brew, but staying within this range is key for optimal results․
