1. A reusable beverage cartridge for use in a beverage forming machine, comprising: a cartridge body having a bottom including a flat surface, a top, a sidewall extending between the bottom and the top, and an interior space, the bottom including an inlet opening and an outlet opening each arranged to respectively receive an inlet needle and an outlet needle of a beverage forming machine, the inlet opening arranged to receive an inflow of liquid from the inlet needle into the interior space and the outlet opening arranged to provide a beverage to the outlet needle, the top of the body having an access opening that provides access to the interior space;a filter basket defining a beverage material space in which to hold a beverage material used to form a beverage, the filter basket having a top opening through which the beverage material space is accessible, an inlet to receive liquid into the beverage material space, and a filter portion to allow flow of beverage out of the beverage material space, the filter basket being receivable into the interior space of the cartridge body through the access opening of the cartridge body; anda cover arranged to removably engage with the top of the cartridge body at the access opening to seal the access opening of the body closed, the cover being removable from the cartridge body to allow removal of the filter basket from the interior space. 2. The cartridge of claim 1, wherein the cover seals the top opening of the filter basket closed when engaged with the cartridge body at the access opening. 3. The cartridge of claim 1, wherein the bottom includes first and second flat surfaces that are parallel and not co-planar, the first flat surface including the outlet opening and the second flat surface including the inlet opening. 4. The cartridge of claim 3, wherein the second flat surface is nearer the cartridge body top than the first flat surface. 5. The cartridge of claim 1, wherein the outlet opening is near a periphery of the bottom and the inlet opening is near a center of the bottom. 6. The cartridge of claim 1, wherein the filter basket includes a bottom that is spaced above the inlet opening with the filter basket received in the interior space. 7. The cartridge of claim 1, wherein the filter basket has a bottom surface opposite the top opening that seals to an interior surface of the body to define an inlet flow path between the inlet opening and the filter basket inlet. 8. The cartridge of claim 7, wherein the filter basket inlet is located at a bottom of the filter basket, and the bottom surface of the filter basket includes an annular portion of the bottom of the filter basket. 9. The cartridge of claim 8, wherein the body includes an inlet chamber in the interior space between the inlet opening and a sealing surface that engages the annular portion of the bottom of the filter basket. 10. The cartridge of claim 1, wherein the filter basket is cylindrical in shape with the top opening located at one end of the cylindrical shape. 11. The cartridge of claim 10, wherein the filter portion is located in an upper portion of a sidewall of the cylindrical shape near the top opening. 12. The cartridge of claim 11, wherein the filter basket includes a rim around the top opening that is spaced above a portion of the body that defines the access opening of the body and engages with the cover. 13. The cartridge of claim 1, wherein the filter basket is arranged in the interior space such that liquid introduced into the inlet opening flows upwardly through the inlet into the beverage material space of the filter basket, flows outwardly through the filter portion and flows downwardly to the outlet opening of the body. 14. The cartridge of claim 1, wherein the sidewall includes a spout portion in communication with the outlet opening.
