Should I use metal wine racks?

Most people think of wood wine racks when contemplating wines cellar racks. However, metal wine cellar racks are just as effective. The benefit of metallic wine racks is that they remain constant in varying temperature ranges and humidities — although, preferably, your wine cellar will be consistent in both these areas. Metallic wines racks also extremely durable and able to hold many bottles at a time. Wrought iron is the traditional steel used for wine racks, but you can also find them in a number of metals and colors. For the illusion of a more substantial collection, combine wood and metal racks in your cellar.
