Vinotemp VT-400 Credenza Four doors (304) Bottle Capacity. The state of the art Wine Mate cooling units are top of the line, and are NOT imported, but made here in the Los Angeles area. This is very important because something this vital to keep your wine cellar cool, should not be trusted with inferior components. The Wine Mate 1500 is UL approved which becomes an essential part when considering a wine cabinet. The wine racks are made with wood which is then interlocked with the aluminum to create a sturdy rack. Although the 3 3/8 is the standard racking (bang for your buck for storing wine), we recommend the upgrade to 3 3/4 racking so that more of the new wines can fit in your cellar. You will loose bottle capacity, but your bottles will fit more easily in the racks. Most of these units are designed with back exhaust, where you need a minimum of 4-6 inches on back, 12 inches on sides, and 6-12 inches above for proper ventilation. We also offer top, side or front exhaust
