Beverage filter cartridge holder

A beverage is brewed by infusing heated liquid with a dry beverage medium contained in a first chamber of a disposable cartridge. The cartridge is internally subdivided by a permeable filter separating the first chamber from a second chamber, with both chambers being closed by piercable lid on one side of the cartridge. During a brew cycle, the cartridge is clamped between confronting arms, an the cartridge lid is pierced by inlet and outlet probes carried by a platen and arranged to communicate respectively with the first and second cartridge chambers. Heated liquid is admitted in to the first chamber via the inlet probe for infusion with the dry beverage medium, and the resulting brewed beverage permeates through the filter into the second chamber from which it exits via the outlet probe.
