In this article, we will delve deep into the world of Chemex brewing, from its history and design to a step-by-step guide on how to make a delicious cup of coffee using this elegant brewing device. Prepare to discover the charm of Chemex coffee!
What is Chemex?
The Chemex is not just a coffee maker; it’s an elegant, hourglass-shaped device that has been enchanting coffee aficionados since its creation in 1941. Invented by German chemist Peter Schlumbohm, the Chemex is renowned for its aesthetic appeal and the unique flavor profile it produces.
Unlike conventional coffee makers, the Chemex uses specially designed filters that are about 20-30% thicker than standard coffee filters. This key feature helps to capture more oils and finer particles, resulting in a crisp, clean cup of coffee. The Chemex is also made from non-porous borosilicate glass, which does not absorb odors or chemical residues, ensuring that every brew remains pure and flavorful.
Why Brew Coffee with Chemex?
There are several compelling reasons to choose Chemex as your go-to coffee brewing method:
1. Flavor Clarity
When brewing with Chemex, the resulting coffee is known for its clarity of flavors. The thicker filter allows the essential oils to pass through while trapping any sediment and bitter compounds. This means you can savor the subtle notes of each coffee variety.
2. Aesthetic Appeal
The Chemex brewing system doubles as a stunning piece of art, making it a beautiful addition to any kitchen. Its clean lines and glass design will impress your guests and provide a stylish brewing experience.
3. Versatility
The Chemex can brew several cups of coffee at once, with models available that accommodate anywhere from three to ten cups. This makes it ideal for both solo brewing and entertaining.
What You Need to Make Coffee with Chemex
Before we dive into the brewing process, let’s ensure you have all the necessary equipment and ingredients:
Essential Equipment
- Chemex coffee maker (choose from a 3, 6, 8, or 10-cup model)
- Chemex paper filters (make sure to use the ones specifically designed for Chemex)
- Gooseneck kettle (for precise pouring)
- Coffee grinder (preferably a burr grinder for uniform grounds)
- Scale (optional, but useful for precise measurement)

The Perfect Coffee-to-Water Ratio
A critical aspect of brewing coffee is the ratio of coffee to water. For a perfect cup with Chemex, a common recommendation is to use 1:15 ratio of coffee to water. This means for every 1 gram of coffee, you should use 15 grams of water. For a single cup of Chemex coffee, you can start with 30 grams of coffee and 450 grams of water, adjusting as per your taste preferences.
Steps to Brew Coffee with Chemex
Now that you’re equipped with the right tools and knowledge, let’s walk through the steps to brew a delightful cup of coffee using Chemex.
Step 1: Prepare Your Chemex
- Unfold a Chemex filter and place it into the top of the Chemex. Ensure that the thicker side of the filter is against the spout. This will help to create a strong filtration while allowing smooth pouring.
- Rinse the paper filter with hot water to eliminate any paper taste and to preheat the Chemex. Dispose of the rinse water.
Step 2: Measure and Grind Your Coffee Beans
- Using the scale, measure out your chosen amount of coffee beans. Remember, 30 grams is a good starting point for 450 grams of water.
- Grind the coffee beans to a medium-coarse consistency, similar to sea salt. Avoid using a fine grind, as it may clog the filter and affect the brew time.
Step 3: Boil Your Water
- Bring your water to a boil in the gooseneck kettle. Allow it to cool for about 30 seconds after boiling, reaching an optimal temperature of about 200°F (93°C). This temperature is ideal for extracting the best flavors from the coffee without causing bitterness.
Step 4: Bloom The Coffee Grounds
- Pour a small amount of water (about double the weight of the coffee) over the coffee grounds to saturate them slowly. This process, known as “blooming,” allows the coffee beans to release carbon dioxide and helps enhance the flavors.
- Allow the coffee to bloom for 30-45 seconds before continuing to pour.
Step 5: Brew the Coffee
- After blooming, slowly pour the remaining water in a circular motion, ensuring that all the coffee grounds are evenly wet. This process should take around 3-4 minutes.
- Avoid pouring water directly on the filter. Instead, focus on the grounds to ensure even extraction.
Step 6: Let It Drip and Serve
- Allow the coffee to finish dripping through the filter entirely. This should take around 4-5 minutes. Avoid rushing this step, as it impacts flavor extraction.
- Once the coffee has dripped through completely, remove the paper filter and discard it along with the used grounds.
Step 7: Enjoy Your Perfect Cup
- Pour the brewed coffee into your favorite mug. Feel free to add milk or sweeteners according to your preference, but many coffee connoisseurs appreciate the clean taste of Chemex brews unadulterated.
Tips for the Best Chemex Coffee
To enhance your Chemex brewing experience, consider these tips:
1. Use Fresh Coffee Beans
Always opt for freshly roasted coffee beans, ideally used within two weeks of roasting for the best flavors. Store them in an airtight container away from light.
2. Experiment with Grind Size
Adjust your grind size according to your taste preferences. A coarser grind may yield a brighter flavor, while a finer grind will produce deeper notes.
3. Control Your Water Temperature
Use a thermometer or let your boiling water rest briefly to reach the optimal brewing temperature. Too hot water may scorch the coffee, while too cool water may under-extract it.
4. Brew in Small Batches
If you’re trying a new coffee bean, consider brewing smaller quantities to perfect the ratios and timing before scaling up.
Cleansing Your Chemex
Cleaning your Chemex after each use is essential for maintaining its integrity and usability:
- Rinse the Chemex with warm water to remove residual oils.
- For deeper cleanings, use a mild dish soap and a soft cloth. Avoid abrasive cleaners or sponges, as these can scratch the glass.
- Never place your Chemex in the dishwasher or microwave, as it is not designed for high-temperature environments.

What is a Chemex and how does it work?
A Chemex is a unique pour-over coffee maker that combines elegance with functionality. Its hourglass shape is made of non-porous borosilicate glass, which preserves the purity of the coffee’s flavor. The Chemex uses specially designed paper filters that are thicker than standard filters, allowing for a slower brewing process that extracts rich flavors and aromas. The design also serves as a beautiful serving vessel, making it ideal for both brewing and presenting your coffee.
To brew coffee using a Chemex, water is heated to the appropriate temperature and then poured over coffee grounds placed in the upper portion of the Chemex. Gravity helps the water seep through the grounds, extracting flavors and oils before dripping into the lower chamber. The result is a clean, crisp cup of coffee that highlights the nuances of the beans used, making it a favorite among coffee enthusiasts.
What equipment do I need to use a Chemex?
To use a Chemex, you will need several essential pieces of equipment. The first is the Chemex itself, which comes in various sizes ranging from 3 cups to 10 cups, depending on your brewing needs.
