ABSTRACT:
A drip brewer is formed with a frusto-conical body adapted to seat over an empty vessel. The lower end of the body includes an infusion chamber covered with a snap fit perforated disc and carrying a measure of loose, i.e. not compacted, roasted and ground coffee with the coffee occupying less than the full chamber volume. Control of brewing water flow into the chamber, wetting and expansion of imbued coffee and flow of the brewage out of the lower end of the chamber result in optimum extraction rate and a predetermined volume of freshly brewed coffee beverage being collected in the vessel.
