The WineKeeper Monterey wine preservation and dispensing system has a professional look that fits in well with a commercial environment, or for the wine connoisseur at home. A pressurized blanket of inert nitrogen protects wine from spoiling and oxidation when being dispensed by the glass from opened bottles. The temperature range in the Monterey for white wine is 42-48° F and 46-68° F for red wine. For optimum performance, a minimum vented air space of 1" each side, 3" behind, and 12" above the unit is required.
