Wine is ideally stored at temperatures between 45 and 65 degrees Fahrenheit. Many wine experts believe that 55 degrees Fahrenheit is the perfect temperature for storing wine.
Both cold and heat can significantly damage wine. Temperatures higher than 70 degrees Fahrenheit can cause wine to go flat, while temperatures that are too cool may result in the corks drying out and shrinking enough to allow the passage of air into the interior of the bottles, which can ruin wine. Wine should also never be frozen because the contents can expand and cause the cork to come completely out. Consistency in temperature is more important in wine storage than aiming for a perfect 55 degree temperature, but wine experts advise that minor variations won't hurt most wines
