Along the same lines, my Chemex is one of my favorite objects. I love the simplicity of the design and the brewing process. I love the consistently tasty brew. I love the way it looks on my kitchen counter. I love the purity of materials.
Admittedly, the 'purity of materials' argument is probably just superstition on my part. I'm not sure if there are measurable benefits to an all-glass brewing receptacle, but it sure makes me feel good. Glass, wood, and leather are materials that I can easily wrap my head around, and somehow that brings extra peace of mind to my whole coffee ritual.
