Brewer

A beverage extraction assembly comprising:

• a frame having at least two spaced apart lead screws and at least two spaced apart columns;
• a drive mechanism coupled to the lead screws;
• a carriage coupled to the drive mechanism for movement with the drive mechanism relative to the frame and coupled to the columns;
• a brew chamber coupled to the carriage for movement with the carriage relative to the frame, the brew chamber configured to receive a brewing substance for forming a brewed beverage when combined with water, the brew chamber positioned between the lead screws and between the columns;
• a water system coupled to the brew chamber and configured to deliver water to the brew chamber;
• a first piston coupled to the frame and sized to be at least partially received in the brew chamber;
• and
• a second piston received in the brew chamber opposite of the first piston,
• wherein the drive mechanism is configured to engage with the lead screws to move the carriage relative to the frame to move the brew chamber toward the first piston to drive the first piston into the brew chamber toward the second piston to compact the brewing substance between the first piston and second piston and force brewed beverage out of the brew chamber through the first piston, the drive mechanism is configured to engage with the lead screws to move the carriage relative to the frame to move the brew chamber away from the first piston to engage the second piston with the frame to drive used brewing substance out of the brew chamber, the lead screws are circumferentially spaced apart from the columns relative to the brew chamber, and the brew chamber is replaceable with at least one other brew chamber of the same configuration or a different configuration.
