Abstract
A coffee brewing device, such as a cold coffee brewing device and related methods are disclosed. The device includes a container, a supported horizontal plate that holds filter paper in place, and a spigot below the horizontal plate. Coffee grounds are placed on the filter, then water is added to the container such that minimal disturbance of the coffee ground bed occurs. When the spigot is opened, liquid is removed in a north/south (up/down) direction through the coffee ground bed. The coffee ground bed serves as a first filter, the filter serves as a second filter, and the chamber below the horizontal plate serves as a coalescing chamber where sediment drops out thus serving as a third filter. The resulting liquid dispensed from the spigot is amber in color and clear.
