Timeless Chemex. Invented in 1941 by the eccentric chemist Dr. Peter Schlumbohm. 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 Bonded™ 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. Pour hot water over grounds and voila! Pair with Chemex Prefolded Filter Squares.
