Details: Known as a pristine coffeemaker, Chemex® employs all of the chemically correct methods for brewing. Its hourglass-shaped flask is made entirely of glass, a chemically inert material that does not absorb odors or chemical residues. The Chemex has no moving parts and will work forever, unless it is dropped or in some other way demolished. Coffee beans and pre-ground coffee contain about 50 different elements. Only two are desirable: aromatic coffee oils and caffeine. The rest is a mixture of acids, fats, oils, and bitter flavor elements that must be removed if the coffee is to have a rich taste. A really good cup of coffee is clear, full-bodied, and aromatic. Chemex filters are 20-30% heavier than competitive brands. They remove even the finest sediment particles as well as the undesirable oils and fats. The formulation of the filter permits the proper infusion time by regulating the filtration rate - not too slow, not too fast. Good infusion of the coffee grounds (as in brewing and steeping tea) gives coffee a richer flavor while at the same time enabling precise fractional extraction, filtering out the undesirable components that make coffee bitter by allowing only the desirable flavor elements of the coffee bean to pass through. The Chemex filter is folded into a cone shape, exactly as in laboratory techniques. This assures uniform extraction since the water filters through all the grounds on its way to the apex of the cone. The Chemex filter is guaranteed not to burst under the weight of the liquid during filtration, and not to break when lifting out the grounds. Full-bodied, richer flavor, from less coffee and as strong as you like without bitterness - that's what the Chemex filter gives you. Pre-Folded filters are not included.
