I received a Chemex coffee maker last week from my wife. I had looked at the maker for a while and she bought it for me out of the blue. As a big fan of coffee this was a fun experiment with a new maker.
I had already been using a french press so I was already used to boiling water and the time needed to make a pot of coffee. The time needed to make a pot is 10-15 minutes including heating the water. The use of a filter is different from a french press but it does cut down on bitterness of coffee.
The Chemex uses a coarse ground coffee to increase the surface of coffee exposed to the water.
The first week of use leads me to decide it is a great way to enjoy coffee. It is not a fast process.
