Assemblies, machines, systems, and methods for the generation of superheated are discussed A steam super-heat assembly is employed for generating superheated steam for the preparation of coffee-based beverages. The assembly includes a body that includes an internal cavity, a heating element that includes heating surfaces positioned within the internal cavity, and a flow path within the internal cavity. The body also includes an input that enables fluid access into the internal cavity and an output that enables fluid egress out of the internal cavity. The heating element heats the heating surfaces of the heating element. The flow path enables fluid to flow from the input, through the internal cavity of the body, and to the output of the body. The heating surfaces form a portion of the flow path. When the fluid flows through the internal cavity, the fluid is in direct physical contact with the heating surfaces.

1. A method for employing a machine for a preparation of a beverage, the method comprising: partially vaporizing a fluid housed within a tank included in the machine by heating the fluid to a vaporizing temperature, wherein a portion of the fluid is transformed to vapor and a portion of the fluid remains in a liquid state;providing the partially vaporized fluid to a super-heater assembly included in the machine and, wherein the super-heater assembly is downstream from the tank and includes a helical member that surrounds a heating element, the helical member receiving the provided partially vaporized fluid;employing the super-heater assembly to further vaporize the fluid by exposing the partially vaporized fluid in the helical member to the heating element to produce further vaporized fluid, the further vaporized fluid containing a greater portion of vapor than in the partially vaporized fluid; andproviding the further vaporized fluid to a heat or froth a milk product. 2. The method of claim 1, wherein the employing the super-heater assembly to further vaporize the fluid causes a heat transfer from the heating element to the fluid within the helical member to heat the partially vaporized fluid above the vaporizing temperature. 3. The method of claim 1, wherein the super-heater assembly further includes a body, wherein at least the heating element, the helical member, and the body form at least a portion of the flow path, the helical member positioned intermediate the heating element and the body, and wherein the helical member directs the received partially vaporized fluid along a concentric path about a longitudinal axis of the body to increase a total amount of thermal energy transferred to the partially vaporized fluid. 4. The method of claim 1, further comprising: brewing one or more shots of espresso; andcombining the heated potable liquid with the one or more shots of espresso. 5. The method of claim 1, wherein at least a portion of the further vaporized fluid includes superheated steam. 6. The method of claim 1, further comprising at least one of: adjusting a flow rate of the partially vaporized fluid from the tank to the super-heater assembly; oradjusting a moisture content of the further vaporized fluid that is provided to the potable liquid by adjusting a temperature of a portion of the super-heater assembly. 7. The method of claim 6, wherein the flow rate of the partially vaporized fluid from the tank to the super-heater assembly is adjusted by controlling one or more valves positioned downstream from the tank and upstream from the super-heater assembly. 8. A method for generating superheated steam within an espresso machine, the method comprising: generating unsaturated steam within a steam tank included in the espresso machine;transmitting the unsaturated steam from the steam tank to a super-heater included in the espresso machine, wherein the super-heater is downstream from the steam tank and includes a body, a heating element, and a helical member that defines a flow path within the body, wherein the body is separate from the steam tank;superheating the unsaturated steam in the flow path by transferring thermal energy generated within the body using the heating element to the unsaturated steam; andproviding the superheated steam to heat or froth milk. 9. The method of claim 8, further comprising: employing the espresso machine, pre-wetting coffee grounds at a first flow rate of water provided to the coffee grounds; andemploying the espresso machine, brewing one or more shots of espresso from the pre-wetted coffee grounds at a second flow rate of water provided to the pre-wetted coffee grounds, wherein the second flow rate is greater than the first flow rate. 10. The method of claim 8, wherein the heating element is positioned within the body and is surrounded by the helical member to form at least a portion of the flow path such that when the unsaturated steam flows through the flow path, at least a portion of the unsaturated steam is in direct physical contact with the heating element. 11. The method of claim 8, further comprising: adjusting a flow rate of the transmitting of the unsaturated steam from the steam tank to the super-heater by employing a flow rate regulating assembly included in the espresso machine. 12. The method of claim 11, wherein a movable control member of the flow rate regulating assembly includes one or more opposing magnets to provide the user with tactile feedback by inducing a mutually attractive force between the movable control member and one of one or more opposing magnets as the movable control member is moved towards the one of the one or more opposing magnets to cause a sensation that the control member is being snapped into place. 13. The method of claim 8, wherein the helical member of the super-heater is intermediate the heating element and the body, wherein the body, the helical member, and the heating element are coaxial about a longitudinal axis of the body, and wherein the superheating the unsaturated steam in the flow path by transferring thermal energy generated within the body to the unsaturated steam further comprises: directing the unsaturated steam along the helical member of the super-heater to expose the unsaturated steam to the heating element to superheat the unsaturated steam by transferring thermal energy from the heating element. 14. The method of claim 8, further comprising: controlling a temperature of the superheating the unsaturated steam in the flow path using one or more thermocouples downstream from the steam tank. 15. A method for preparing a coffee-based beverage, the method comprising: brewing a volume of coffee;generating steam in a steam tank;providing the steam to a super-heater assembly located downstream from the steam tank;employing the super-heater assembly to heat at least a portion of the steam to a temperature that is greater than a vaporization temperature of water at a pressure of the super-heater assembly;providing the heated steam to heat or froth milk; andcombining at least a portion of the heated or frothed milk with the volume of coffee. 16. The method of claim 15, wherein the providing the steam to a super-heater assembly and the employing the super-heater assembly to heat at least a portion of the steam further comprises: providing the steam to a body of the super-heater assembly through an input of the body of the super-heater assembly, wherein the input enables fluid access into an internal cavity of the body, and wherein the body includes an output that enables fluid egress out of the internal cavity; andheating the at least a portion of the steam using a heating element that includes one or more heating surfaces positioned within the internal cavity of the body of the super-heater assembly to heat the portion of the steam, wherein the heating element is configured and arranged to heat the one or more heating surfaces, and wherein a flow path within the internal cavity of the body enables fluid to flow from the input, through the internal cavity of the body, and to the output of the body, wherein at least a portion of the one or more heating surfaces of the heating element form at least a portion of the flow path such that when the fluid flows through the internal cavity of the body, at least a portion of the fluid is in direct physical contact with the one or more heating surfaces. 17.
