As I said before, the temperature of wine is important
and can adversely affect your tasting and drinking experience. I have often heard that "white wines should be served chilled, and red wines should be served at room temperature". This is a good rule of thumb, but obviously "room temperature" is not a fixed target.
Your kitchen refrigerator is most likely around 35°F. This is too cold for any wine. If you serve a white wine at this temperature, it will have virtually no flavor! Here are some guidelines for a few types of wines:
Asti Spumanti: 40-42°F
Champagne: 43-48°F
Chardonnay: 46-50°F
Chianti, Zinfandel: 58-60°F
Cabernet, Burgundy: 60-65°F
Port: 65-67°F
Remember, these are just guidelines. On a really hot day, you can get away with serving wine a little cooler. If you have room, buy a wine chiller or a wine fridge.
These appliances will allow you to keep your wine exactly at the recommended level. Even if you don't have a wine fridge, try to stick to the recommended wine serving temperatures and you will ensure that you get the most flavor and aroma from every glass!
