When properly stored, wines can maintain their quality and in some cases improve in aroma, flavor, and complexity as they age. </li></ul><ul><li>Some wine experts contend that the optimal temperature for aging wine is 55 °F (13 °C). </li></ul><ul><li>Wine refrigerators offer an alternative to wine cellars. They are available in capacities ranging from small 16-bottle units to furniture pieces that can contain 400 bottles. </li></ul>
