A countertop pressurized beverage system includes an outer housing, and an inner flexible Mylar bag containing a potable liquid, such as beer or a carbonated beverage, requiring pressurization. A closed plastic container capable of withstanding substantial pressure encloses the flexible bag, and is mounted with the housing. A compressor supplies air to the closed plastic container at a pre-set level, in order to maintain carbonation in the potable liquid. A thermoelectric cooling unit is mounted on the bottom of the countertop unit to provide cooling, to a plate which is mounted in thermally conductive proximity below the closed plastic housing at the bottom thereof where the flexible bag rests against the bottom of the plastic container. A cap makes threaded engagement with mating threads on a wide mouth opening on the closed plastic container; and the cap has an inwardly extending central tube around which the mouth of the flexible bag is secured. A closure plug is threaded at the center of the cap, and a spigot assembly may be screwed into the closure cap and perforates the inner wall thereof, so that fluid may be dispensed from the flexible bag through the spigot. A spigot may be screwed into the center of the cap, thereby avoiding the need for a closure plug. Means other than perforation may be used by the spigot assembly to disengage the closure plug.
