The following information is from the book - The Wine Lover's Guide to Auctions
The temperature of the bottle of wine is critical to the drinker's pleasure. Serving a wine wither too warm or too cold will prevent its balance, complexity, and finesse from showing. Both red and white wines are best served at cellar temperature (50 degrees F to 70 degrees F) rather than room temperature (68 degrees F to 72 degrees F). Once served, the wine will gradually arm up to room temperature.
For those without temperature-controlled storage, an easy rule of thumb to get the temperature right is the 20/20 rule:
* Put red wines into the fridge twenty minutes before serving
* Take white wine out of the fridge twenty minutes before serving

This book is a wonderful teaching tool not only for buying and selling wine at auctions, but for every day knowledge.
I love wine, but serving it at the proper wine temperature has been a challenge for me since I do not have a wine cellar or cooler. Finally I found an easy to remember 20/20 rule in the book -The Wine Lover's Guide to Auctions - The Art & Science of Buying And Selling Wines that helped with with a simple formula.
