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.
