What is Chemex coffee?

Chemex is a popular pour-over coffee brewing method that produces a clean, flavorful cup of coffee. It was invented in 1941 by Dr. Peter Schlumbohm, a chemist with a passion for coffee. The Chemex coffee maker consists of an hourglass-shaped glass container, a wooden collar, and a special paper filter.

With its elegant design and excellent functionality, the Chemex coffee maker has become a favorite among coffee enthusiasts worldwide. It allows for precise control over the brewing process, resulting in a consistently delicious cup of coffee.

Why choose Chemex for brewing coffee?

There are several reasons why coffee lovers choose the Chemex as their preferred brewing method:

  • Superior flavor extraction: The thick, bonded paper filter used in the Chemex removes most of the coffee oils and solids, resulting in a clean and smooth coffee with no bitterness.
  • Optimal brewing temperature: The Chemex’s glass construction allows for ideal heat retention during brewing, ensuring that the coffee is brewed at the perfect temperature.
  • Simplicity and elegance: The Chemex’s simple yet beautiful design makes it a standout piece in any kitchen or coffee setup.
  • Easy to clean: The Chemex can be quickly cleaned by simply removing the filter and rinsing the glass container.

How many scoops of coffee for Chemex?

The recommended amount of coffee for a Chemex brew depends on the desired strength and the size of the Chemex you have.

Size of Chemex Number of Scoops
3-cup (1-pint) Chemex 3 tablespoons
6-cup (2-pint) Chemex 6 tablespoons
8-cup (2-quart) Chemex 8 tablespoons

It is important to note that these measurements are for a medium grind size. Adjust the amount of coffee based on your preferred taste and grind size.

Ways to achieve the perfect Chemex brew

1. Select high-quality coffee beans

Start with freshly roasted whole coffee beans. Look for beans that have been roasted within the last two weeks for optimal flavor.

2. Grind your coffee correctly

For Chemex brewing, a medium grind size is recommended. Too fine of a grind can result in over-extraction, while too coarse of a grind can lead to under-extraction.

3. Preheat the Chemex

Before brewing, rinse the Chemex filter with hot water to remove any paper taste and preheat the glass container. This helps maintain the temperature stability during the brewing process.

4. Bloom the coffee

After placing the coffee grounds in the filter, pour a small amount of hot water (about twice the weight of the coffee) over the grounds and let it bloom for about 30 seconds. This allows the coffee to release trapped gases for better flavor extraction.

5. Pour in a steady, circular motion

Begin pouring hot water in a circular motion, starting from the center and working your way outwards. Aim for an even saturation of the coffee grounds.

6. Brew time and water ratio

The total brew time for a Chemex brew is typically around 4-5 minutes. Use a water-to-coffee ratio of 16:1 (16 parts water to 1 part coffee) as a starting point and adjust according to your taste preferences.

7. Enjoy your Chemex coffee

Once the brewing process is complete, remove the filter and pour the rich, smooth coffee into your favorite mug. Take a moment to savor the aroma and flavors of your perfectly brewed Chemex coffee.

Tips for a great Chemex experience

1. Experiment with different coffee beans

Try different varieties and origins of coffee beans to discover new flavor profiles and find your favorites.

2. Use a gooseneck kettle

A gooseneck kettle provides better control over the pouring process, allowing for precise water distribution and extraction.

3. Store your coffee properly

Keep your coffee beans or grounds in an airtight container in a cool, dark place to preserve their freshness and flavor.

4. Clean your Chemex regularly

Remove the wooden collar and wash the glass container and filter holder with warm, soapy water after each use. This ensures that no residue or oils build up, affecting the taste of your coffee.

5. Share the joy of Chemex brewing

Invite friends and family over for a Chemex brewing session and share the love for this exceptional brewing method.

Difference between Chemex and other brewing methods

While there are several brewing methods available, the Chemex stands out in a few key ways:

  • Thicker filters: Chemex uses specialized thick filters that remove more oils and sediment compared to other pour-over methods, resulting in a cleaner cup of coffee.
  • Heat retention: The glass construction of the Chemex helps maintain a consistent brewing temperature, which is essential for proper extraction.
  • Design aesthetic: The Chemex’s elegant hourglass shape and wooden collar make it a visually appealing brewing device that adds a touch of sophistication to any coffee setup.

Other pour-over methods, such as the V60 or Kalita Wave, may offer slightly different flavor profiles or brewing techniques, but the Chemex remains a popular choice for its unique combination of aesthetics, functionality, and clean taste.


In conclusion, the Chemex is a remarkable coffee brewing method that allows for full control over the brewing process, resulting in a clean and flavorful cup of coffee. By following the recommended measurements and brewing techniques, you can enjoy a consistently excellent Chemex brew. Remember to experiment with different coffee beans, grind sizes, and water ratios to find your perfect cup. Whether brewing for yourself or sharing the Chemex experience with others, embrace the joy of creating and savoring a delicious cup of Chemex coffee.

FAQs (Frequently Asked Questions)

Question 1: How do I determine the number of scoops of coffee for my Chemex?

Chemex is known for its ability to brew a smooth and clean cup of coffee. The general rule of thumb is to use one tablespoon of coffee for every six ounces of water. However, the ideal ratio may vary depending on personal taste preferences. If you prefer a stronger cup of coffee, you can try increasing the coffee-to-water ratio by using one tablespoon of coffee for every four to five ounces of water. Experiment with different ratios to find the perfect balance that suits your taste buds.

Question 2: Can I adjust the brewing ratio for a smaller or larger Chemex?

Absolutely! The typical Chemex size is a 6-cup or 8-cup brewer. If you have a smaller Chemex, such as the 3-cup version, you may need to adjust the brewing ratio accordingly. For a smaller Chemex, you could use one tablespoon of coffee for every four ounces of water to maintain a balanced brew. Conversely, if you have a larger Chemex, such as the 10-cup version, you might want to increase the ratio to one tablespoon of coffee for every seven to eight ounces of water to achieve the desired strength and flavor.

Question 3: How do I grind the coffee beans for my Chemex?

To brew the perfect cup of coffee with a Chemex, a medium-coarse grind is recommended. This coarser grind size ensures optimal extraction during the pour-over process, resulting in a clean and flavorful brew. If the grind is too fine, it can lead to over-extraction and a bitter taste. If the grind is too coarse, the extraction may be insufficient, resulting in a weak cup. Invest in a quality burr grinder to achieve a consistent and precise grind size.

Question 4: Should I preheat the Chemex before brewing?

Preheating the Chemex is highly recommended to maintain optimal brewing temperature. Simply pour some hot water into the Chemex and let it sit for a few minutes before discarding the water. This process warms up the glass and helps to retain heat during the brewing process. By preheating the Chemex, you ensure that the coffee extraction occurs at the desired temperature and prevent heat loss, resulting in a more consistent and enjoyable cup of coffee.

Question 5: How can I ensure even extraction when brewing with a Chemex?

To achieve even extraction, start by pouring a small amount of hot water over the coffee grounds, just enough to saturate them. Allow the coffee to bloom for about 30 seconds, during which carbon dioxide is released, resulting in an enhanced flavor profile. Then, gradually pour the remaining water in a slow, steady circular motion, ensuring that all the grounds are fully saturated. This pour-over technique promotes even extraction and helps to release the desired flavors from the coffee grounds. Additionally, make sure to pour the water evenly across the entire bed of coffee grounds, avoiding concentrated pours that may lead to over-extraction in certain areas.
