What is the ideal climate for long-term wine storage?
The ideal temperature for long-term wine storage is generally 55°F. This allows for slow and proper aging of the wine. A temperature that is too hot will increase the speed of aging and a temperature too low will slow the pace of aging. However, rapid changes in temperature are more damaging to your wine than a steady high or low temperature in the cellar. The proper humidity level has been determined to be 60 to 65 percent relative humidity. A humidity level any higher (at a temperature of 55°F) will be too humid and cause mold issues and deterioration of labels. A humidity level that is too low will result in a dry cork, which allows the opportunity for oxygen to reach your wine and cause oxidation.
