  4. At 45 seconds, start the second pour, pouring in a wiggling motion until the volume reaches about a fingertip down from the top of the rim or around 450g of water.
  5. At 1 minute and 45 seconds, fill the brewer flush to the top or approximately 700g of water.
  6. At 4 minutes, lift the filter to check for enough volume and then remove it completely.
  7. Give the Chemex a gentle swirl, and you’re ready to serve two cups of delicious brewed coffee.

What Is a Chemex and Its Necessities

The Chemex is a coffee maker invented in 1941 by a chemist named Peter Schlumbohm. It has a simple but unique design that allows excess air to escape from the bottom of the carafe through a paper filter, resulting in a perfect rate of filtration. The Chemex is made with a single piece of borosilicate glass and features a wooden collar and rawhide tie for aesthetics. It comes in various sizes, with the 6 and 8-cup versions being the most popular.

To use a Chemex, you will also need Chemex filters, a coffee scoop or scale for measuring coffee, a grinder for grinding coffee beans, and a gooseneck kettle for precision pouring. Fresh coffee beans are also essential for the best results.

How to Use a Chemex Coffee Maker, Best Coffee for Chemex, and Cleaning

Using a Chemex coffee maker is a simple and rewarding process. To begin, heat your water to a boil or to 205°F if you have a temperature-controlled kettle. This ensures the ideal brewing temperature for your coffee.

Next, place the Chemex filter in the brewer and rinse it with hot water. This preheats the carafe and removes any paper flavor that may affect the taste of your coffee.

Now it’s time to measure and grind your coffee. Use 2 tablespoons (10 grams) of coffee beans for every 6 ounces of water. This ratio can be adjusted according to your personal preference. For a medium grind consistency, aim for the texture of Kosher salt.

Once your coffee is ready, calculate your desired coffee-to-water ratio and let the water cool slightly to avoid scalding the coffee grounds.

The brewing process begins by pouring hot water over the coffee grounds in a slow, controlled manner. This allows the coffee to bloom, releasing its flavorful oils and aromas. Let the coffee bloom for about 30 seconds, then continue pouring the remaining water in three equal parts. This ensures even saturation and helps maintain the desired brew time.

Once the brewing process is complete, carefully remove the filter and enjoy your freshly brewed coffee. The Chemex brewing method produces a clean and smooth cup of coffee with balanced floral notes.

For the best coffee flavor, choose beans that are well-suited for a Chemex. African coffee, known for its bright and tea-like taste, pairs particularly well with the Chemex brewing process. Experiment with different coffee origins and roast levels to find your perfect cup.

After each use, it’s important to properly clean your Chemex to maintain its pristine condition. Wash it with warm water, using a soft-bristled brush to remove any residue. Avoid using scented soap, as it may leave behind unwanted flavors.

Using a Chemex coffee maker allows you to experience the art of pour-over brewing and indulge in the vibrant flavors of freshly brewed coffee. With the right technique, a Chemex becomes more than just a brewing device—it becomes a centerpiece for bringing out the best in your favorite coffee beans.
