A system and method for extraction is provided. The method includes filling a chamber of a vessel at least partially with at least one liquid ingredient. The method also includes diffusing at least one displacement material having a higher molecular mass than terrestrial air and a lower molecular mass than the liquid ingredient through at least one port located adjacent to or along a bottom surface of the vessel for releasing oxygen from the liquid ingredient. The method also includes discharging the released oxygen from the chamber through an outlet adjacent to or along a top surface of the vessel to provide a substantially anaerobic atmosphere. The method also includes introducing at least one additional ingredient into the chamber of the vessel. The method also includes agitating the at least one liquid ingredient and the at least one additional ingredient while maintaining the anaerobic atmosphere in the chamber.

A steeping apparatus (10) includes a container (12) and a partition (22) dividing the container into upper and lower chambers (24, 26). The partition has a central aperture (32, FIG. 2) which interconnects the chambers and is arranged to trap a volume of air 38 in the lower chamber when the container is filled with liquid. Hot water poured into the upper chamber (24) passes through the aperture to partially fill the lower chamber, trapping a volume of air (38). Brewing material (34) located in the upper chamber (24) steeps in the hot water to produce a beverage and gradually sinks into the lower chamber (26) through the aperture. The air (38) trapped in the lower chamber applies a force to the liquid inhibiting movement of liquid between the chambers so that the brewing material (34) is isolated from the beverage. In other embodiments, the partition is pressed down through the container after brewing to isolate the brewing material.

A coffee brewing system includes a brew vessel adapted to receive water and ground coffee to produce and store a brewed beverage. The brew vessel includes a filter and a magnet stirrer in the lower portion of the brew vessel. The magnet stirrer creates a water vortex for brewing the coffee. The used coffee grounds are allowed to settle on the filter creating a bed of used coffee grounds and the coffee is then filtered through both the bed of used coffee grounds and the filter and collected in a coffee storage container.
