“The colder a wine, the less tart, sweet and aromatic it seems.” The flavor of white wine comes primarily from just these three elements: acid and sugar, which you taste on your tongue, and aromatics, which have to evaporate before your nose can detect them. When you buy a bottle of wine, you’re paying for flavor (and alcohol, of course). If chilling masks the main flavor-producing elements, then every time you chill white wine, you’re throwing money away.
Therefore, drink the not-so-good ones cold and the very good ones just barely chilled.
Still, it is best to chill white wine before serving. You can keep it in the fridge. Once opened all wines start to deteriorate with the effect of oxygen. Recork white (& red wines) as soon as possible and keep uprightin the fridge door. Expect it to keep one day, most will drink OK for a couple but you'll notice the change in flavor. For long term storage of wine, there is no difference between reds and whites. Keep horizontal in a cool, dark, dry, vibration free place. But only about 1% of all wines need to be aged, most wines are meant to be drunk within 2 years. So don't worry if your conditions are not ideal -- wine is more robust than most people think."
