Wine is very sensitive to temperature changes, so controlling temperature in a wine refrigerator ensures that the wine is not at risk for damage. Additionally, temperature controls allow flexibility for reaching the ideal environment for white and red wines.
Temperatures higher than 70 degrees Fahrenheit can cause wine to prematurely age. Wine exposed to warmer temperatures are likely to suffer from flat aromas and flavors. On the other end of the spectrum, wines exposed to freezing temperatures may expand and push the cork out. Safe temperature storage for wine is between 45 and 65 degrees Fahrenheit. The main goal of wine storage is to keep the bottles at a consistent temperature.
Temperature controls make it easier to reach the desired temperature consistently. Small adjustments can be made to accommodate seasonal temperature changes in the home. Controlling minor temperature variations are important for those storing wine for more than a few years.
Red wines and white wines are best stored at different temperatures. White wines do best between 46 and 56 degrees Fahrenheit, while and red wines are best between 58 and 68 degrees. Storage units with a single compartment and temperature controls can be adjusted to accommodate either red or white wines at any given time.
