It may be surprising how much the materials used to store and bottle the wine can have an impact on its market value. For example, the value of a wine bottle is largely determined by the quality of the label alone. While this may be surprising to most wine consumers, the idea is if the label is damaged, it can foreshadow the quality of the wine itself. Labels are traditionally paper-based; therefore, a relative humidity of 70 percent is on the high limit in terms of preserving its quality. Any higher and the relative humidity will damage the label. Any lower and the glue keeping the label intact can dry out.
