Abstract: A recirculation brewing process and apparatus for performing the same are disclosed. In one embodiment, the coffee brewing process comprises: a brew chamber to hold a packed chamber of coffee grounds; and a pump to force a liquid under pressure through the packed chamber of coffee grounds over multiple brewing cycles to extract coffee flavor from the coffee grounds into the liquid using a temperature agnostic infusing brewing process, the liquid under pressure causing a pressure differential over tunnels within the coffee grounds and over the brew chamber when forced through the chamber each cycle of a plurality of cycles to cause extraction of the flavor into the liquid.

Abstract: An infusing apparatus and method for using the same are disclosed. In one embodiment, the apparatus comprises a portable device for infusing a liquid with flavor from material, where the device comprises: a liquid container to store a liquid; a brew chamber to hold the material; and a pump to generate a pressure differential over tunnels within the material and over the brew chamber.
