| Abstract: |
Systems and methods for brewing beverages in accordance with the present invention can improve the flavor of brewed beverages and reduce the vertical space required for a system using suction. One such assembly comprises a brewing chamber adapted to hold a filter having an intake duct for receiving fluid for brewing, and an output duct for expelling a brewed beverage. The brewing chamber is positioned above a pressurizable container, or carafe, having an adjustable standpipe and containing the fluid. The carafe has a heated base, which when heated causes pressure to build up, forcing the fluid up the standpipe, through a check valve, through the intake duct and into the filter. Once substantially all of the fluid has been urged into the brew chamber, the heat is removed, creating a partial vacuum that pulls the brewed beverage back into the carafe. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

First Claim:
Show all 13 claims |
What is claimed is:
1. A two-chamber brewing system comprising:
- a first chamber adapted for holding a filter and capable of receiving and expelling a fluid;
- wherein the first chamber is connected with a frame having a pedestal to position the second chamber such that a sealing surface of the first chamber can be brought into contact with the second chamber so that the standpipe is isolated from atmosphere;
- wherein the pedestal includes one of grooves and tracks to align the sealing surface with the standpipe; and
- a second chamber capable of creating a pressure differential between the first chamber and the second chamber, the second chamber having a heated base and a standpipe to allow fluid to flow between the first chamber and the second chamber;
- wherein the second chamber includes one of tracks and grooves to engage the one of grooves and tracks of the pedestal.
