Chemex Classic Series Coffeemaker, likely the 3-cup version.
It is an elegant pour-over style coffee maker designed in 1941 by chemist Dr. Peter Schlumbohm.
The hourglass-shaped flask is made from non-porous, heat-resistant borosilicate glass that does not absorb odors or chemical residues.
It features a distinctive polished wooden collar and leather tie, allowing for handling when hot.
The design is simple, requiring proprietary, thicker paper filters to produce a clean, clear, and bitter-free coffee.
