The Chemex remains a staple in every coffee enthusiast's arsenal. Its design has endured, unchanged (wood handle, leather cord, tapered glass and paper filter), since its invention in 1941 by Peter Schlumbohm. Schlumbohm’s designs were characterized as “a synthesis of logic and madness,”. Coffee from a Chemex is very similar to that from a drip, but there’s more room for error. To guarantee the best results, grind your beans more coarsely than you would for a ceramic drip, and offer extra attention to the pour rate. This level of care yields a delicate and nuanced coffee, with plenty left over to share with friends.
