Abstract: A method of preserving and controlling dispensed liquids is achieved exclusively and uniquely through operation of direct or indirect actuation of gas control valves acting systemically upon the liquid container and its contents so as to cause and control the flow of dispensed liquids held within the container.

Abstract: A potable liquid dispensing system includes a data reader that permits unattended beverage tastings, as well as simplified wine dispensing at restaurants and the like. A wine marketing system, including tastings facilitated by the dispensing system, permits a potential buyer of wine to sample small portions of the wine without the assistance or supervision of an employee.

Abstract: A storage and dispensing system for potable liquids, e.g., wine, includes an inclined rack which holds a bottle with the neck down, a dispensing head sealing the bottle neck, and an inert gas supply system in fluid communication with the head. As liquid is dispensed from the bottle, low-pressure gas is admitted into the bottle, to inhibit oxidation of the wine. The system includes one or more self-sealing elements in the head itself and/or in gas lines between the head and a gas regulator. Because the self-sealing elements prevent air from entering into the system when the gas lines are detached, each bottle can have a dedicated head and bottles can be swapped out for dispensing, without the need for replacing bottle heads, sparging, or using more than one source of gas.
