If you're into coffee, you probably know about Chemex. Invented by a chemist in 1941, in the permanent design collection of the Museum of Modern Art and the Smithsonian, unchanged today; the Chemex coffeemaker is the essence of purity and simplicity. A borosilicate, heat-resistant, laboratory-glass carafe and a proprietary paper filter are all that touch the brewing coffee. Your coffee is pure, flavorful and without bitterness or sediment every time, no matter how strong you make it.
Brewing coffee in a Chemex is simple. All you do is pour just-off-the-boil water over ground coffee in the Chemex filter, in a few simple stages. Here's a look at the process
straight from Chemex. It's much like the coffee hipster's "pour-over" method, only it's been around for about 70 years. Chemex filters have been developed by Chemex and are essential to the process These special filters are 20-30% heavier than reguar coffee filters and remove even the finest sediment particles as well as the undesirable oils and fats. Chemex filters permit the proper infusion time by regulating the flow rate; not too slow and not too fast. The proper infusion of the coffee grounds gives coffee a richer flavor while at the same time filtering out the undesirable components which make coffee bitter.
