Chemex Brew Guide

The Chemex Coffeemaker is a manual pour-over style glass coffeemaker, invented by Peter Schlumbohm in 1941. It consists of an hourglass-shaped glass flask with a conical funnel-like neck and proprietary filters, made of bonded paper, that are thicker than the standard paper filters used for a drip coffeemaker. The thicker paper of the Chemex filters removes most of the coffee oils and makes coffee that is much "cleaner" than coffee brewed in other coffee-making systems.
