The Chemex® coffeemaker, together with Chemex-Bonded® Coffee Filter, makes perfect coffee. Clear, pure, flavorful and without bitterness or sediment every time. The coffee only comes in contact with the scientifically designed filter and non-porous glass.
With the Chemex® method, you can make coffee as strong as you like without bitterness. Perfect for iced coffee and coffee flavoring for gourmet recipes. Because of its purity, Chemex® brewed coffee can be covered and stored in the refrigerator for reheating…without losing its flavor!
The CHEMEX® coffeemaker was invented in 1941 by the eccentric chemist Dr. Peter Schlumbohm. Throughout his career he developed over 300 patents, ranging from cocktail shakers to automobiles. His focus was on making everyday objects more functional, attractive and enjoyable to use.
When designing the CHEMEX®, Schlumbohm desired to not only make brewing the perfect cup simple, but also to have the vessel be a thing of beauty. Being a chemist, he studied and understood clearly the chemistry behind the extraction of flavor and caffeine from coffee beans.
It was this knowledge that led him to invent the double bonded CHEMEX® paper filters for a perfect extraction every time. For the carafe, Schlumbohm was inspired by the Bauhaus school of design and non-porous labware that would impart no flavor of its own.
Using these elements he fashioned the hourglass shape that has now become an iconic part of American history. Made simply from one piece of borosilicate glass and adorned with a wooden collar and rawhide tie, the CHEMEX® is pure in both form and function.
It has been recognized and awarded by both the scientific community as well as the art and design communities. The CHEMEX® can be found in museums throughout the world and is included in the permanent collection at the Brooklyn Museum, Corning Museum of Glass and MOMA, NY.
The Museum of Modern Art displayed it as one of the best-designed products in 1943.
The CHEMEX® coffeemaker was also selected by the Illinois Institute of Technology as one of the 100 best designed products of modern times.
CHEMEX® Corporation has been a family owned company for over 30 years. We are honored to carry on the historical and iconic legacy of Dr. Schlumbohm and his Chemex coffeemaker.
Q | How can I avoid bitter coffee?
A | If the water that comes into contact with the coffee grounds is too hot, you will extract bitter elements from the coffee. The water should not be boiling when poured on the coffee grounds. Coffee oils, fats and sediment are the natural parts of the coffee bean that causes bitterness by forming as the brew ages. The longer the coffee sits the stronger it tastes. (Actually it is bitterer, not stronger.)
Q | Can I reheat coffee brewed with a Chemex?
A | Chemex may be reheated without being bitter. Make sure that brewed coffee is stored in a sealed glass container. Exposure to air causes loss of taste.
Q | Can I heat a Chemex coffeemaker on the stove?
A | The Chemex can be placed directly on a glass top stove or over a low gas flame to be kept warm. If you have an electric stove with exposed coils, you may purchase the wire grid (TKG) which can be placed between the coils and the Chemex to protect the coffeemaker. The coils should be set to a low temperature.
Q | What advantages do Chemex filters offer?
A | Chemex filters are 20-30% heavier (more absorbent) to remove undesirable sediment particles and oils. Chemex filters were scientifically formulated to permit proper infusion time while filtering out sediment, oil, and fats. Infusion gives coffee a richer flavor and makes possible the fractional extraction of only the desirable parts of the coffee bean.
Q | What temperature should the water be when brewing?
A | The Chemex system was developed to provide the fractional extraction of only the desirable part of the coffee grounds.The coffee is brewed at and held at a temperature of between 180-200°F to avoid chemically altering the taste and making the coffee bitter.
