Step 1: Gather Your Materials

Before you begin, make sure you have the following items:
– Chemex coffee brewer
– Chemex bonded filter
– Freshly roasted coffee beans
– Grinder
– Electric kettle or stovetop kettle
– Digital scale
– Timer
– Spoon or stirrer
– Mug or carafe

Step 2: Grind Your Coffee Beans

To achieve the best flavor extraction, it is crucial to grind your coffee beans just before brewing. Use a burr grinder and set it to a medium-coarse grind size. Aim for a consistency similar to sea salt.

Step 3: Prepare the Chemex Brewer and Filter

Unfold the Chemex bonded filter and place it inside the brewer, ensuring that the triple-fold portion is aligned with the pour spout. Rinse the filter with hot water to remove any paper flavor and preheat the brewer. Discard the rinse water.

Step 4: Measure and Add Coffee Grounds

Using the digital scale, measure the desired amount of coffee grounds. A general guideline is to use 1 gram of coffee per 15 grams of water. For example, if you’re brewing 300 grams of water, use 20 grams of coffee. Add the coffee grounds to the filter.

Step 5: Bloom the Coffee

Pour a small amount of hot water, approximately double the weight of the coffee grounds, over the grounds. This step, known as blooming, allows the coffee to degas and enhances the extraction process. Let the coffee bloom for around 30 seconds.

Step 6: Begin the Pour

Start the timer and slowly pour the remaining hot water over the coffee grounds in a circular motion, starting from the center and moving outward. Maintain a steady and controlled pour, making sure all the coffee grounds are saturated evenly.

Step 7: Allow the Coffee to Drip

Once you have poured all the water, let the coffee drip through the filter into the bottom of the Chemex brewer. Aim for a total brew time of around 3-4 minutes. Adjust the grind size or pouring speed if needed to achieve the desired extraction time.

Step 8: Serve and Enjoy

Once the coffee has finished dripping, remove the filter and discard it. Pour the brewed coffee into your favorite mug or carafe and savor the aroma and flavors of your freshly brewed Chemex coffee.
