Abstract:
A system and method for reducing the amount of caffeine in an existing volume of brewed coffee. The brewed coffee contains a predetermined level of caffeine. To reduce the caffeine, a caffeine filter is provided. Furthermore, a coffee receptacle is provided to hold the decaffeinated coffee. A filter chamber is positioned over the coffee receptacle. The caffeine filter is placed in the filter chamber. Brewed coffee is dripped, poured, or otherwise advanced into the filter chamber. At least some of the brewed coffee flows through the caffeine filter and into the coffee receptacle. This reduces the level of caffeine of the filtered coffee entering the coffee receptacle. The system also enables a single source of brewed coffee to produce cups of both regular coffee and decaffeinated coffee, using only one type of regular ground coffee.

Claim (Index 1):
A filter for decaffeinating brewed, caffeinated coffee, comprising:\n a single-use filter packet constructed of filter material having a porosity; wherein the filter packet has upper and lower layers of filter material entirely enclosing an interior volume, and wherein the filter packet has a predetermined shape and size to be removably received by an existing filter holder; and at least five grams of powdered caffeine adsorbing activated charcoal contained in the interior volume of the filter packet, and wherein the caffeine adsorbing material is separate from the layers of filter material of the single-use packet; whereby, when brewed, caffeinated coffee is poured through the single-use filter packet, at least 90% of the caffeine is removed from the brewed coffee by the at least five grams of powdered caffeine adsorbing activated charcoal contained in the filter packet; wherein the powdered caffeine-adsorbing activated charcoal contained in the filter packet has a particle size; and wherein the porosity of the filter material of the filter packet is a function of the particle size.
