Abstract

A brew cartridge has a bowl with a flange extending laterally from its exterior and apertures in its bottom. A pod containing brewing material is located within the bowl and covered by a panel having apertures. Panel retention features in the interior of bowl keep the panel and pod in place. The brew cartridge fits in a brewing machine with a multiple piece chamber which matches the cartridge and clamps on the flange. The brew machine passes pressurized hot water through the cartridge to brew a beverage. The water enters through the panel and exerts at the bottom. Some embodiments of the cartridge have a drain bowl formed in the bottom of the bowl. The drain bowl has the apertures of the bottom of the bowl through and may have drain panel covering it.
