One of the design criteria for the Brazen was that it would fit the 6 Cup Chemex. The Chemex is 8 1/2″ tall and the space in the BraZen is 9″. Since this sized Chemex isn’t a perfect fit, we are working on our own glass carafe design that should be available in the near future. Try a five-cup hand-blown Chemex (the six-cup more commonly available is just a bit too big to fit)
