About Sleeping Grape Wine Cellar Storage

About storage

Optimum conditions for storing wine include stable temperatures around 58 degrees F, humidity of approximately 50 - 80%, and darkness -- the exact environment of a cave, or of many a cool, damp basement.

Temperature

The ideal cellar or wine storage temperature is 55-65 degrees F. Cool temperatures slow the aging process, increasing complexity and character of the wine over time. Likewise, high temperatures speed the aging process, preventing a wine from developing complexity over time. However, it is preferable to store wine at a constant temperature which may a be a bit warmer or cooler than the ideal 55-65 degrees F. Temperature fluctuations cause wine to expand and contract, which causes the cork to push out and pull in and eventually may loosen and expose the wine to oxygen.

Humidity

Humidity is also important when storing wine. Humidity levels over 80% may encourage mold, while extremely dry conditions may cause high levels of evaporation and exposure to oxygen, spoiling the wine. Wine stored in darkness is more likely to retain its clarity. Light reacts to proteins in the wine to form a haze as well as other unpleasant effects, such as off aromas and flavors. At home, basements are usually ideal for storing wine because of their cool, constant temperature and darkness. If no basement is available, consider storing wine in a little-used closet in an air-conditioned part of your home. If you are planning a serious wine collection and have no suitable storage location, then a proper refrigerated wine cellar would be recommended.
