a cartridge holder being configured to be removable coupled with the funnel, the cartridge holder being configured to receive liquid from the first outlet, the cartridge holder including a support structure positioned on a lower end of the cartridge holder, the support structure having a second outlet and an oblong shape, the support structure securing the system in an upright position, wherein a bottom length of the support structure is longer than a diameter of an upper surface of the cartridge holder, the bottom length of the support structure is shorter than a diameter of an upper surface of the funnel, and a bottom width of the support structure is shorter than the diameter of the upper surface of the cartridge holder, and the bottom width is shorter than the bottom length, wherein the support structure is positioned below the cartridge holder; a tack positioned on the support structure, the tack being configured to extend into a lower surface of a hollow body of the cartridge holder, the tack being configured to puncture a brewing pod positioned within the cartridge holder, the tack including a stem and a conical top, a first circumference of the stem being less than a second circumference of a base of the conical top, wherein the conical top includes a cutout extending around ninety degrees of the conical top from an apex of the conical top to the base, the base being positioned adjacent to the stem, the tack being misaligned with a center of the support structure. ### Claim 2 (depends on 1) The system of claim 1, further comprising: a raised sealing surface positioned at a bottom of the funnel such that when the cartridge holder comes into contact with the raised surface, a seal is formed. ### Claim 3 (depends on 1) The system of claim 1, further comprising: a flow separator positioned below the first outlet and within the cartridge holder when the cartridge holder is coupled to the funnel, the flow separator being configured to reduce flow vertexes in a filter positioned within the cartridge holder. ### Claim 4 (depends on 3) The system of claim 3, wherein the flow separator includes a plurality of fins that are positioned equidistance apart from each other. ### Claim 5 (depends on 1) The system of claim 1, wherein the brewing pod is configured to be positioned within the cartridge holder. ### Claim 6 (depends on 5) The system of claim 5, wherein a distance between a lower surface of the brewing pod and the lower surface of the cartridge holder is shorter than a length of the stem. ### Claim 7 (depends on 1) The system of claim 1, further comprising: a filter configured to store coffee grinds, the filter including a mesh screen and first tapered sidewalls, the filter being configured to be positioned within the cartridge holder. ### Claim 8 (depends on 7) The system of claim 7, wherein the cartridge holder includes second tapered sidewalls, a first angle of the first tapered sidewalls being greater than a second angle of the second tapered sidewalls. ### Claim 9 (depends on 1) The system of claim 1, further comprising: a foot device being configured to be removably coupled with the support structure. ### Claim 10 (depends on 9) The system of claim 9, wherein an upper surface of the foot device includes a first opening and a second opening, the first opening having a first length that is longer than that of the bottom length of the support structure, the second opening having a second length that is shorter than that of the bottom length. ### Claim 11 (depends on 10) The system of claim 10, wherein the support structure is configured to rotate in a first direction while aligned with the first opening to couple the foot device and the support structure together, wherein responsive to rotating the support structure in the first direction the bottom length of the support structure is positioned below the second opening. ### Claim 12 (depends on 11) The system of claim 11, wherein the support structure is configured to rotate in a second direction while aligned with the second opening to decouple the foot device and the support structure.
