A cooling sink is positioned within a cooling chamber having a 0.75-1.50 gallon capacity, for directly contacting pressurized beer therein, the cooling sink having a substantial surface portion in contact with the beer for enabling heat extracted from said beer to be rapidly conveyed to said cooling device. The cooling sink has a deep trench therein for reducing the mass of the cooling portion while increasing the surface area contacting the beer. A valve is employed at the top of the cooling chamber to allow the cooling reservoir to be completely filled with beer during periods of use, and any developing undesired foam can be removed from time to time by opening this valve. Also, the pickup tube attached to the dispensing tap picks up beer from the bottom of the cooling chamber, to minimize foam in the beer dispensed.
