History of Chemex Coffeemakers
Invention of the Chemex Coffeemaker
The Chemex coffeemaker, an iconic piece of kitchen equipment loved by coffee enthusiasts around the world, was invented by Dr. Peter Schlumbohm in 1941. Dr. Schlumbohm, a German chemist, was driven by his passion for making the perfect cup of coffee. He believed that the brewing process should be simple and elegant, resulting in a coffee that showcased the full flavor and aroma of the beans. With this vision in mind, he designed the Chemex coffeemaker, combining science and artistry to create a masterpiece of coffee brewing.
Design and Functionality
The design of the Chemex coffeemaker is as unique as it is functional. Made from a single piece of borosilicate glass, it features an hourglass shape with a wide bottom and a narrow neck. The brewer utilizes a special Chemex filter, which is thicker than traditional coffee filters, resulting in a clean and crisp cup of coffee. The design of the Chemex allows for slow and controlled pouring, which ensures the extraction of all the flavors from the coffee grounds.
Recognition and Popularity
Since its creation, the Chemex coffeemaker has gained widespread recognition and popularity among coffee enthusiasts and professionals alike. Its sleek and elegant design has become a symbol of coffee culture, and it is often featured in modern art and design exhibitions. The Chemex has also been recognized for its contribution to the world of coffee, receiving multiple awards for its design, functionality, and the superior quality of coffee it produces. Today, the Chemex coffeemaker is a staple in many homes and coffee shops, loved for its ability to make a consistently exceptional cup of coffee.
Benefits of Using Chemex Coffeemakers
Superior Coffee Flavor
One of the main benefits of using a Chemex coffeemaker is the superior flavor it brings to every cup. The slow and controlled pouring technique and the thick Chemex filter allow for a precise extraction process. This results in a rich and clean cup of coffee with a well-balanced flavor profile. The Chemex filters also remove any sediment or bitterness, giving the coffee a smooth and enjoyable taste.
Efficient Extraction Process
The design of the Chemex ensures a complete and efficient extraction process. The hourglass shape and the thickness of the filter promote a longer contact time between the coffee grounds and the water, allowing for optimal extraction of flavors. The slow pouring technique ensures that every bit of the coffee is evenly saturated, resulting in a well-extracted brew with no under or over extraction.
Simplicity of Use
Using a Chemex coffeemaker is a breeze, even for those who are new to the world of pour-over brewing. The process involves a few simple steps, from preparing the equipment to enjoying the final cup of coffee. The clear glass construction of the Chemex allows for easy monitoring of the brewing process, giving users full control over the extraction and allowing them to fine-tune their technique.
Chemical-Free Brewing
Another advantage of using a Chemex coffeemaker is that it provides a chemical-free brewing experience. The borosilicate glass construction of the Chemex ensures that no harmful chemicals or flavors leach into the coffee during the brewing process. This allows coffee lovers to enjoy a pure and untainted cup of coffee, free from any unwanted tastes or odors.
Eco-Friendly Material
The Chemex coffeemaker is not only a delight to use but also an environmentally conscious choice. The borosilicate glass used in its construction is both durable and sustainable, making it a long-lasting option for coffee brewing. Unlike single-use coffee pods or paper filters, the Chemex can be used over and over again, reducing waste and minimizing the environmental impact of your coffee brewing routine.
Craftsmanship and Materials
Handcrafted Design
Each Chemex coffeemaker is a labor of love, handcrafted with precision and attention to detail. The combination of science and artistry results in a coffeemaker that is not only functional but also visually stunning. The dedication to craftsmanship is evident in every aspect of the Chemex, from the smooth curves of the glass to the precisely positioned wooden collar.
Quality Borosilicate Glass
The Chemex coffeemaker is made from borosilicate glass, a special type of glass known for its durability and heat resistance. This type of glass is resistant to thermal shock, meaning it can handle extreme temperature changes without cracking or breaking. The use of borosilicate glass ensures that the Chemex will last for years, providing coffee lovers with a reliable and long-lasting brewing companion.
Wood Collar and Leather Tie
Adding a touch of elegance and warmth to the Chemex is the wooden collar and leather tie. The wooden collar serves as an insulating grip, making it easy to handle the Chemex while keeping the coffee hot. The leather tie not only adds a decorative element but also secures the Chemex filter in place, ensuring a snug fit and allowing for optimal coffee extraction.
Heat Resistant Glass Handle
The Chemex features a heat-resistant glass handle that allows for safe pouring and handling of the coffeemaker. The handle is designed to stay cool to the touch, ensuring that you can comfortably pour your coffee without the risk of burning yourself. This thoughtful feature adds to the overall usability and convenience of the Chemex.
Sturdy Construction
Durability is a key characteristic of the Chemex coffeemaker. The borosilicate glass, combined with the sturdy construction, makes the Chemex robust enough to withstand daily use and accidental bumps. The hourglass shape provides stability, preventing any tipping or spilling during the brewing process. With proper care and maintenance, the Chemex can be a beloved brewing companion for many years to come.
Steps to Brew Coffee with Chemex
Prepare the Equipment
Before you begin brewing, make sure to gather all the necessary equipment. This includes the Chemex coffeemaker, the Chemex filter, freshly roasted coffee beans, a grinder, a kettle for heating water, and a scale for precision.
Grind the Coffee Beans
Grind the coffee beans to a medium-coarse consistency, similar to sea salt. The precise grind size will depend on personal preference and the desired strength of your coffee. A burr grinder is recommended for a consistent grind size.
Pre-wet the Filter
Unfold the Chemex filter and place it in the brewer with the triple-folded side facing the pouring spout. Pour hot water over the entire filter, wetting it thoroughly. This step helps to eliminate any paper taste from the filter and preheats the Chemex.
Add Coffee and Water
Add the ground coffee to the filter, leveling it out for an even extraction. Start by pouring a small amount of water, just enough to saturate the coffee grounds, and let it rest for about 30 seconds. This allows the coffee to “bloom,” releasing carbon dioxide and enhancing the flavors.
Controlled Pouring Technique
Begin pouring the water in a steady and circular motion, starting from the center and spiraling outwards. Aim to pour slowly, maintaining a consistent rate that allows for a gentle flow of water through the coffee grounds. The total brewing time should be around 4-5 minutes.
Brewing Time and Ratios
The ideal brewing time for a Chemex coffee is around 4-5 minutes. However, you can adjust the brewing time to suit your taste preferences. As for the coffee-to-water ratio, a common guideline is to use 1:15 ratio, meaning 1 gram of coffee per 15 grams of water. Experiment with ratios to find the perfect balance for your palate.
Enjoying the Perfect Cup
Once the brewing process is complete, carefully remove the filter from the Chemex. The coffee is now ready to be enjoyed. Pour it into your favorite mug or serve it to guests, savoring the aroma and flavors that the Chemex brings to every cup.
Tips and Tricks for Chemex Brewing
Choosing the Right Coffee Beans
To achieve the best tasting coffee with your Chemex, it’s important to start with high-quality, freshly roasted coffee beans. Look for beans that are freshly roasted and within their peak flavor window. Experiment with different bean origins and flavor profiles to find your perfect cup of coffee.
Optimal Water Temperature
The ideal water temperature for brewing coffee with a Chemex is between 195°F and 205°F (90°C and 96°C). Bring the water to a boil and allow it to cool for about 30 seconds before starting the brewing process. Using water within this temperature range helps to extract the best flavors from the coffee grounds.
Grind Size and Consistency
The grind size and consistency of your coffee beans are crucial factors in achieving a balanced and flavorful cup of coffee. As mentioned earlier, a medium-coarse grind size is generally recommended for Chemex brewing, but you can adjust it to your liking. Aim for consistency in grind size to ensure even extraction.
Pouring Techniques
Experiment with different pouring techniques to achieve different flavor profiles in your coffee. For a stronger and more robust cup, pour the water faster, while for a lighter and more delicate cup, pour the water slower. Play around with pouring patterns and directions to explore the full potential of your Chemex.
Experimenting with Brew Ratios
Brew ratios, or the ratio of coffee to water, can greatly impact the strength and flavor of your coffee. Start with the recommended 1:15 ratio and adjust it to your taste. Increase the amount of coffee for a stronger cup or decrease it for a milder one. Pay attention to how the flavor changes with different ratios.
Cleaning and Maintenance
To keep your Chemex in optimal condition, it’s important to clean it regularly. After each use, rinse the glass brewer and filter holder with warm water. For a more thorough cleaning, use a mild dish soap and a soft brush to remove any coffee residues. Allow the Chemex to air dry before storing it.
Variations and Accessories
Chemex Filters
Chemex filters are specially designed to fit the Chemex coffeemaker, ensuring a clean and sediment-free brew. These filters are thicker than regular coffee filters, which helps to remove any undesirable flavors or oils from the coffee. Chemex filters are available in both pre-folded squares and circular shapes.
Chemex Kettle
The Chemex kettle is a beautifully designed pour-over kettle that complements the Chemex coffeemaker perfectly. With its long, slim spout and ergonomic handle, the Chemex kettle allows for precise and controlled pouring, ensuring an even extraction. It is a favorite among coffee enthusiasts who value precision and craftsmanship.
Chemex Ottomatic Coffee Maker
For those who prefer a more hands-off approach to brewing, the Chemex Ottomatic coffee maker offers convenience without compromising on quality. This automatic pour-over machine replicates the same slow and controlled pouring technique of a manual Chemex brew, resulting in a consistently delicious cup of coffee.
Customizable Wooden Handle
Add a personal touch to your Chemex with a customizable wooden handle. Some companies offer the option to engrave or personalize the wooden collar, allowing you to make your Chemex truly unique. This customization option makes the Chemex a thoughtful gift for coffee enthusiasts.
Alternative Brewing Methods
While the Chemex is primarily known for its pour-over brewing method, it can also be used for other brewing techniques.

It’s a versatile piece of equipment that allows coffee lovers to experiment with different brewing methods.
