Present embodiments generally relate to a single-serve beverage cartridge for use with a single-serve coffee brewer. In some embodiments, the cartridge has a body portion, a first filter element, and a second filter element. The cartridge can include a single serving of coffee or another beverage component or precursor. The cartridge can be formed of a biodegradable and/or compostable material. In some embodiments, at least one of the filters is configured to stretch when pressed by a tamping head, thereby allowing the tamping head to be received in the cartridge to facilitate tamping of the beverage component or precursor.

1. A single-serve beverage cartridge comprising: a generally hollow body portion comprising a chamber, a sidewall, a first end, and a second end, the first end having a radially outwardly extending lip, the second end having a radially inwardly extending flange;a beverage component or precursor positioned in the chamber;a first filter element joined with the lip, the first filter element configured to allow passage of liquid therethrough and to engage with a tamping head of a beverage preparation machine, the first filter element elastically deformable between a first position and a second position, wherein the first filter element is configured such that: in the first position, the first filter element is positioned outside the chamber of the hollow body portion;in the second position, the first filter element is recessed within the chamber of the body portion and is engaged with the beverage component or precursor, thereby enabling compressive force from the tamping head to be applied, through the first filter element, to the beverage component or precursor; anda second filter element joined with the flange and configured to allow passage of liquid therethrough. 2. The cartridge of claim 1, wherein the first filter comprises polylactic acid. 3. The cartridge of claim 1, wherein the first filter element is configured to deform into the second position by stretching. 4. The cartridge of claim 1, wherein the first filter element is configured to deform into the second position by unfolding. 5. The cartridge of claim 1, wherein the first filter element and the second filter element are configured to not be at least one of: separated from the hollow body portion, pierced, or ruptured. 6. The cartridge of claim 1, wherein the cartridge comprises biodegradable materials. 7. The cartridge of claim 1, wherein the body portion and at least one of the first and second filter elements comprise polylactic acid. 8. The cartridge of claim 1, wherein the first filter element is configured to stretch between about 1 mm and about 2 mm along an axial axis of the cartridge. 9. The cartridge of claim 1, further comprising a frame configured to support the body portion. 10. The cartridge of claim 9, wherein the frame comprises a network of struts, the struts coupled with the sidewall. 11. The cartridge of claim 1, wherein at least one of the first and second filter elements comprise a plurality of layers. 12. The cartridge of claim 11, wherein at least one of the first and second filter elements comprise first and second layers with a third layer positioned therebetween. 13. The cartridge of claim 12, wherein the first and second layers comprise woven fibers and the third layer comprises non-woven fibers. 14. The cartridge of claim 1, further comprising a baffle coupled with the second filter element, the baffle configured to direct a flow of liquid around the baffle and through the second filter element. 15. The cartridge of claim 14, wherein the second end comprises a restricting orifice. 16. The cartridge of claim 1, wherein the beverage component or precursor comprises espresso coffee grounds.
