The top end includes a flange to which a cover is sealed. A bottom cover of the sleeve seals the cartridge and 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 sleeve has a series of vertically oriented channels which allow for the brewed beverage to flow out of the sides of the filter hag 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.
