What is a Chemex Glass Coffee Maker?

The Chemex Glass Coffee Maker is a beautifully designed pour-over coffee brewing device that combines art and science to deliver a superior coffee brewing experience. It was invented in 1941 by Dr. Peter Schlumbohm, a German chemist, and has since become an iconic symbol of elegance and precision in the coffee world. The Chemex consists of a glass container, a polished wood collar, and a leather tie, which not only serves as an aesthetic feature but also provides a comfortable grip while pouring.

How does it work?

The Chemex Glass Coffee Maker works on the principle of pour-over brewing, which involves manually pouring hot water over coffee grounds in a filter. The unique design of the Chemex, with its hourglass-shaped glass container and thick paper filters, allows for optimal extraction of flavors and oils from the coffee grounds, resulting in a clean and flavorful cup of coffee.

Why choose a Chemex Glass Coffee Maker?

There are several reasons why coffee enthusiasts choose the Chemex Glass Coffee Maker over other brewing methods. Firstly, the Chemex produces a clean and balanced cup of coffee with no sediments or bitter notes, thanks to its thick filters that remove any unwanted impurities. Secondly, the beautiful design of the Chemex adds a touch of elegance to any kitchen or coffee station. Lastly, the Chemex is a sustainable and eco-friendly brewing method as it requires no electricity and produces no waste other than the paper filters, which are biodegradable.

How to Use a Chemex Glass Coffee Maker

Step 1: Gather the ingredients

Before you begin brewing with your Chemex Glass Coffee Maker, make sure you have all the necessary ingredients. You will need freshly roasted coffee beans, a quality coffee grinder, a Chemex Glass Coffee Maker, Chemex paper filters, a kettle, and hot water.

Step 2: Grind the coffee beans

To achieve the best flavor, it is recommended to grind your coffee beans just before brewing. For the Chemex, a medium-coarse grind is ideal. This grind size resembles sea salt or coarse sand and allows for a balanced extraction.

Step 3: Preheat the Chemex

To ensure the temperature stability of your brew, preheat the Chemex by pouring hot water into it and swirling it around. This will warm up the glass and prevent any heat loss during the brewing process.

Step 4: Rinse the filter

Place a Chemex paper filter into the top section of the brewer, making sure the thicker side is facing the pouring spout. Rinse the filter with hot water to remove any papery taste and to preheat the Chemex further.

Step 5: Add coffee grounds

Measure out the desired amount of coffee grounds based on the coffee-to-water ratio you prefer. A general guideline is to use 1 tablespoon of coffee for every 5 ounces of water. Place the coffee grounds into the rinsed filter and shake the Chemex gently to level the coffee bed.

Step 6: Blooming

Start the brewing process by pouring a small amount of water, about twice the weight of the coffee grounds, onto the bed of coffee. This step is known as blooming and allows the coffee to release trapped gases and ensures even extraction. Allow the coffee to bloom for about 30 seconds.

Step 7: Pouring Technique

Slowly pour hot water over the coffee grounds in a circular motion, starting from the center and moving outward. Aim to pour at a consistent pace and maintain a gentle circular motion to ensure an even saturation of the coffee grounds.

Step 8: Brew Time

The total brew time for a Chemex typically ranges between 3 to 5 minutes. Adjust the pouring speed and water volume to control the brew time and achieve your desired strength and flavor profile.

Step 9: Serve and Enjoy

Once the desired amount of coffee has been brewed, carefully remove the filter and discard it. Place a lid on the Chemex to keep the coffee warm. Serve the coffee in your favorite mug or a Chemex glass and savor the delicious flavors of your perfectly brewed cup of coffee.

Advantages and Disadvantages of Using a Chemex Glass Coffee Maker

  • Customizable brewing: With the Chemex, you have full control over the brewing variables, allowing you to fine-tune your coffee to your preferred taste.


While the Chemex Glass Coffee Maker offers many advantages, there are also a few potential drawbacks to consider:

  • Time-consuming: The pour-over brewing process with a Chemex requires time and attention to detail, which may not be suitable for those looking for a quick and convenient brewing method.
  • Requires skill and practice: Achieving a consistently great cup of coffee with a Chemex may take some practice and experimentation with brewing variables.
  • Delicate and fragile: The glass construction of the Chemex makes it susceptible to breakage if mishandled or dropped.

Tips for Brewing with a Chemex Glass Coffee Maker

Tip 1: Use quality, freshly roasted coffee beans

The quality of your coffee beans plays a significant role in the final taste of your coffee. Opt for freshly roasted beans and experiment with different origins and roast levels to find your preferred flavor profile.

Tip 2: Pay attention to water temperature

Water temperature affects the extraction process, so it’s crucial to use water that is between 195 to 205 degrees Fahrenheit (90 to 96 degrees Celsius) for optimal results. If you don’t have a thermometer, allow your kettle to boil and then let it sit for about 30 seconds before pouring.

Tip 3: Practice pouring techniques

Pouring water over the coffee grounds in a slow, controlled, and circular motion is essential for even saturation. Practice your pouring technique to achieve consistent results and avoid over or under-extraction.

Tip 4: Experiment with brewing variables

The amount of coffee, water-to-coffee ratio, grind size, and pouring speed all contribute to the final taste of your brew. Be open to experimentation and adjust these variables to find your perfect cup of coffee.
