This device, which looks like a laboratory apparatus, was in fact invented by a chemist named Peter Schlumbohm in 1941. Its main feature: Proprietary, chemically bonded filters. These filters are of a thicker gauge than most paper filters. For this reason, Chemex grind is often in fact coarser than most pour over methods, despite the large opening.

Chemex is excellent for serving several cups of coffee. Depending on the size of the model, you can do a single serving or brew for a group.
