Step-by-Step Guide to Brewing Coffee with a Chemex
Now that you’ve gathered your equipment and ingredients, let’s dive into the step-by-step process for brewing coffee with a Chemex.
Step 1: Gather Your Equipment
Make sure you have:
- Chemex coffee maker
- Chemex filters
- Fresh coffee beans
- Burr grinder
- Scale
- Timer
- Filtered water
- Heat source (kettle)
Step 2: Measure Your Coffee and Water
The standard coffee-to-water ratio is about 1:16. This means for every gram of coffee, you’ll need about 16 grams of water. For instance, if you plan to brew 30 ounces (approximately 850 grams) of coffee, utilize about 53 grams of coffee.
Step 3: Grind Your Coffee
Using a burr grinder, grind the coffee beans to a medium-coarse consistency, similar to sea salt. This grind size is ideal for Chemex as it prevents over-extraction.
Step 4: Prepare the Chemex
Insert a Chemex filter into the top of the Chemex, ensuring that the thicker side faces the spout. Rinse the filter with hot water to eliminate any papery taste and warm up the Chemex. Discard the rinse water.

Add the ground coffee into the filter, ensuring it’s even. You should see a little mound in the center of the filter, which allows for even extraction.
Step 6: Pre-Wet the Coffee Grounds
Start the brewing process by pouring a small amount of hot water (just off the boil, around 200°F) over the coffee grounds. This stage, known as blooming, allows gases to escape and enhances the flavor. Let it bloom for about 30 seconds.
Step 7: Brew the Coffee
After blooming, slowly pour the remaining water over the coffee in a circular motion. Start from the center and work your way outwards, then back to the center. This method ensures even saturation of the coffee grounds.
Step 8: Wait for Extraction
Allow the water to extract the coffee for about 3 to 4 minutes. You’ll notice that the coffee will drip into the Chemex below.
Step 9: Serve and Enjoy
Once the coffee has finished dripping, remove the filter with the spent grounds. Your coffee is ready to be served! Enjoy the rich, clean flavors that only a Chemex can deliver.
Tips for Perfecting Your Chemex Brewing
To ensure you’re getting the best results, here are a few tips to keep in mind:
1. Experiment with Grind Size
Each coffee bean has its unique flavor profile. Depending on the beans you choose, you might need to adjust the grind size for optimal extraction.
2. Adjust Coffee-to-Water Ratio
Feel free to adjust the coffee-to-water ratio based on your preference. If you prefer bolder coffee, increase the coffee amount; for a milder taste, reduce it.
3. Maintain Water Temperature
Using water that’s too hot can lead to bitterness. Stick to a temperature between 195°F and 205°F for the best results.
4. Keep Your Equipment Clean
After each brew, ensure that you thoroughly clean your Chemex and filters. This prevents any residues that could affect flavor in future brews.
Common Mistakes to Avoid
Although brewing coffee with a Chemex is straightforward, beginners often make common mistakes:
1. Incorrect Grind Size
Using coffee that is too fine can result in over-extraction, while coffee that is too coarse can lead to under-extraction.
2. Not Blooming
Skipping the blooming phase can rob your coffee of crucial flavors. Always remember to bloom!
3. Over- or Under-Watering
Improper water ratios can lead to unsatisfactory brews. Stick to the recommended ratio for the best results.

What is a Chemex and how does it work?
The Chemex is a pour-over style coffee maker that was invented in 1941 by Peter Schlumbohm. It features a unique hourglass shape and is made of non-porous glass, which doesn’t absorb odors or chemical residues. The design is not only aesthetically pleasing but also functional, as it ensures optimal extraction of coffee flavors through its specially designed filters.
The Chemex works by using a simple brewing method: hot water is poured over coffee grounds placed in a filter. The water then flows through the grounds, extracting the coffee’s flavors and aromas before dripping into the bottom reservoir. The thick paper filters used with a Chemex trap sediment and oils, resulting in a clean and bright cup of coffee.
What coffee grind size should I use for a Chemex?
For brewing with a Chemex, it is recommended to use a medium-coarse grind size. The consistency of the grind is crucial, as a finer grind can lead to over-extraction and a bitter flavor, while a coarser grind may result in under-extraction, leaving the coffee weak and lacking depth.
To achieve a medium-coarse grind, aim for a texture similar to sea salt. If you’re using a burr grinder, adjust it until you find the grind size that produces a balanced cup of coffee. Experimentation is key, so don’t hesitate to adjust your grind to match your taste preferences.
How much coffee and water should I use for brewing?
The ideal coffee-to-water ratio for Chemex brewing is typically 1:15 to 1:17, depending on your taste preferences and the specific beans used. A general guideline is to start with about 1 gram of coffee for every 15-17 grams of water. For example, if you use 30 grams of coffee, you would brew with about 450-510 grams of water.
Measuring your coffee and water accurately will help achieve a consistent brew. A digital scale is highly recommended for precision. Adjusting the ratio will allow you to explore different flavor profiles, so feel free to experiment to find the perfect balance that suits your palate.
How long should the brewing process take?
The Chemex brewing process typically takes between 4 to 5 minutes from the moment you start pouring water until the last drop of coffee drips into the vessel. This timing can vary based on factors such as grind size, coffee freshness, and the specific brewing technique used.
To achieve optimal extraction during the brewing process, pour water in stages. Begin with a bloom pour of about double the weight of coffee, allowing it to sit for 30-45 seconds. Then, continue pouring in a circular motion until you reach the desired final weight. Keeping track of time will help you refine your technique.
