Beverage cartridge and method for beverage formation using filter aid

A method and apparatus for forming a beverage involves the use of a filter aid, e.g., that is provided in a beverage cartridge with a beverage medium in a dry state. In one embodiment, a cartridge including a dried fruit material may also include a filter aid, such as perlite, diatomaceous earth or cellulose, that is mixed together with the fruit material. The filter aid may assist in flow through the beverage medium or through a filter, e.g., by helping prevent the clogging of pores of a filter used to remove particulate from a beverage formed by interaction of the beverage medium with water introduced into the cartridge. Thus, the filter aid may permit the use of some beverage media that would otherwise clog a filter and/or prevent proper dissolution of materials in the beverage media without the filter aid.
