1. A low-cost disposable beverage cartridge capable of providing a beverage having a visually appealing crema layer on top of the beverage comprising:

  • a predetermined amount of flavor-containing materials which provides a beverage when interacted with pressurized water;

    a containing chamber containing said flavor-containing materials, said containing chamber having a cartridge inlet for connecting to a mounting head to receive pressurized water from a pressurized water source and to allow the water to interact with said flavor-containing materials under pressure therein to produce a beverage;

    a cartridge outlet opening for discharging the beverage produced in said containing chamber into a container; and

    a crema generator located between said cartridge outlet opening and said containing chamber for producing a visually appealing crema for the beverage, said crema generator comprising a filter for filtering the beverage produced in said containing chamber, a collection chamber located downstream of said filter for receiving the beverage from said filter and an orifice located on said collection chamber for the beverage received therein;

    wherein the filtration openings of said filter are adapted to be of sufficiently small size to prevent the solid or un-dissolved flavor-containing materials from reaching and clogging said orifice; and

    wherein said orifice of said crema generator is adapted to be of sufficiently small size to generate a jet of beverage of sufficiently high speed to cause said visually appealing crema to form in the beverage before said beverage is discharged at said cartridge outlet opening.
