A chemist invented the Chemex 70 years ago and it is unchanged today. I started using a Chemex about a year ago. I like the simplicity and control you get with it and it makes the exact amount I want to drink at one time.
I have been through 3 drip makers, 1 espresso machine and several french presses. In the end I wanted to go cheaper and simpler and that led me to the Chemex. For a fuller history of the inventor and invention have a look at Collector’s Weekly.
