Abstract: A beverage filter cartridge for use in a single serve beverage brewing machine, the cartridge including a open ended cup with an open top and closed bottom with a cup-shaped filter pouch containing a beverage material sealed to the inside thereof proximate to a top end. The top end includes a flange to which a cover is sealed to prevent spoilage of the beverage material by atmospheric oxygen. The cartridge includes a filter bag with a dry beverage material. The inner surface of the cup has a series of vertically oriented channels which allow for the brewed beverage to flow out of the sides of the filter bag and down the channels before exiting the cartridge at the bottom. The brewed beverage can flow out of the bottom of the cartridge either via the side of the filter bag through the channels or through the bottom of the filter bag.
