A beverage dispenser includes a vessel, a dispensing tap, a dispenser assembly, and a dispensing tube. The vessel defines an internal volume, a lower opening, and an upper opening. The dispensing tube couples the dispensing tap to the dispenser assembly. The dispenser assembly includes a liquid level gauge structure (gauge structure), a riser tube, a lower housing, and an upper housing. The riser tube is positioned within a gauge structure and defines a riser volume. A gauge volume is defined between the gauge structure and the riser tube. The lower housing is configured such that the riser volume and the gauge volume are in fluid communication with the internal volume. The upper housing is configured such that the internal volume is in fluid communication with only the gauge volume and the riser tube is in fluid communication with a volume defined by the dispensing tube.

1. A beverage dispenser comprising: a vessel that defines an internal volume, a lower opening, and an upper opening;a dispensing tap;a dispenser assembly; anda dispensing tube that couples the dispensing tap to the dispenser assembly, wherein the dispenser assembly includes: a liquid level gauge structure,a riser tube that is positioned within a liquid level gauge structure, wherein the riser tube defines a riser volume, and wherein a gauge volume is defined between the liquid level gauge structure and the riser tube,a lower housing, a portion of which penetrates the vessel at the lower opening, wherein the lower housing is configured such that at the lower housing, the riser volume and the gauge volume are in fluid communication with the internal volume, andan upper housing, a portion of which penetrates the vessel at the upper opening, wherein the upper housing is configured such that at the upper housing, the internal volume is in fluid communication with only the gauge volume and the riser tube is in fluid communication with a volume defined by the dispensing tube. 2. The beverage dispenser of claim 1, further comprising a regulator cap assembly that is configured to at least partially seal a mouth of the vessel and to regulate a pressure applied to a beverage retained in the internal volume, wherein the pressure applied to the beverage forces the beverage into the riser volume and the gauge volume via the lower housing and provides a counter pressure to gauge volume at the upper housing. 3. The beverage dispenser of claim 1, wherein: in an assembled configuration of the dispenser assembly, a first end of the riser tube and a first end of the liquid level gauge structure are secured to the vessel by the upper housing and a second end of the riser tube and a second end of the liquid level gauge structure are secured to the vessel by the lower housing;the dispenser assembly includes a cinch nut that is configured to be attached to an upper housing; andthe cinch nut is a single fastener that maintains the dispenser assembly in the assembled configuration. 4. The beverage dispenser of claim 1, further comprising a shuttle that is configured to be positioned in the upper housing, wherein: the shuttle defines a shuttle channel that surrounds a portion of the riser tube such that the gauge volume is in fluid communication with the internal volume;the shuttle includes a lower surface that is configured to contact the liquid level gauge structure; andthe shuttle defines one or more O-ring retaining structures configured to retain one or more of O-rings. 5. The beverage dispenser of claim 1, wherein: the lower housing includes a lower vented housing that defines a pressure gauge volume, a lower volume, and a gauge volume channel;the lower volume is in fluid communication with the riser volume via a first restriction; andthe gauge volume is in fluid communication with the lower volume via a second restriction and the gauge volume channel. 6. The beverage dispenser of claim 1, further comprising a pitot, wherein: the lower housing includes a lower vented housing that defines a pressure gauge volume, a lower volume, and a gauge volume channel;the pressure gauge volume is fluidly coupled to the internal volume via the pitot;an outer lower housing volume is defined between the pitot and the lower vented housing; andthe riser volume is fluidly coupled to the internal volume via the outer lower housing volume. 7. The beverage dispenser of claim 1, further comprising a pressure gauge received by the lower housing such that the pressure gauge indicates a pressure in the internal volume, wherein: the liquid level gauge structure includes a viewing window that is substantially transparent and graduations that indicate a volume of a beverage in the gauge volume; andthe dispensing tap includes a rocker valve and a lock pin, wherein the lock pin is configured to engage a rocker of the rocker valve to prevent actuation of the rocker valve. 8. The beverage dispenser of claim 1, wherein the vessel includes a double-wall construction that includes a vacuum space defined between an exterior wall of the vessel and an interior wall of the vessel. 9. The beverage dispenser of claim 8, wherein: one or both of the lower opening and the upper opening include an air-tight brazed interface formed along an angled portion of the exterior wall and an angled portion of the interior wall; andthe angled portion of the exterior wall and the angled portion of the interior wall are oriented towards the internal volume of the vessel. 10. The beverage dispenser of claim 8, wherein one or both of the lower opening and the upper opening include an air-tight welded joint formed along a weld portion of the interior wall and an angled portion of the exterior wall.
