We have put together some helpful tips on wine storage:
Wines must be stored in a cool, dark place. Direct sunlight or even fluorescent light can cause wine to be ‘light struck,’ which gives it an unpleasant odor. That’s why most bottlers use the darker bottles. They offer better protection against harmful light. If you can’t keep your bottles entirely out of the light, then it helps to wrap them in cloth.
Did you ever wonder why you always see wine stored on its side? If stored upright for a long period of time, the corks will dry out. Once this happens, air eventually gets to the wine causing spoilage. Most wine connoisseurs store their wine label side up. This makes it easier to notice any sediments that could have formed in the wine during storage.
Keep the temperature constant. This is especially important if wine is to be stored for long periods of time, say over one year. Temperatures should not exceed 75˚F (24°C). At 75°F, wine will begin to oxidize. Most wine enthusiasts agree that the ideal temperature for storing a varied wine collection is 54°F (12.2°C). If temps drop below 54°F for brief periods of time, this will only slow down the aging process but won’t harm the wine.
