Using Wine Refrigerators
The Correct Temperatures
For bottles that you plan on keeping for more than six months before consuming, or are laying down for aging, you may need to consider using wine refrigerators. The storage temperature of wine is considered ideal at a temperature of 50 to 55 degrees Fahrenheit and a humidity of seventy percent humidity. Temperatures below this slow the aging of the wine but otherwise have really no impact. If you live in the northern latitudes and are able to find a natural cavern, cellar or basement that maintains a fairly steady temperature in the summer and does not freeze in winter then you should not need to use wine refrigerators for the storage of the wine.
White wines are best served at 45 degrees. Normal general refrigeration maintains a temperature of from 32 to 40 degrees and is typically a little too cool for white wine. However, for most of the world allowing the wine to warm just a little is not considered a problem and the use of wine refrigerators are not required.
Red wines should be served at about 60 degrees, which is a little cooler than most room temperatures which are in the 65 degree range in winter and 70 in summers with air conditioning. For these wines general refrigeration is too cold for serving and you may want to consider locating a place where you can maintain airflow over the wine to keep the temperature over the bottles a little lower than room temperature. However, should you prefer and can afford, you can solve this problem with the use of wine refrigerators.
Wine refrigerators are in extensive use commercially. They can range in size from those that can hold just a few bottles to those that are designed to keep 100s of bottles or more. Wine cellar operations typically utilize several wine refrigerators. Each device maintains the wine inside at the requisite temperature. There would be wine refrigerators for long-term storage and for the staging of the various varietals for serving.
