WINE TEMPERATURE

"Humidity" Some degree of humidity is required in order to keep wines with cork enclosures from drying out. Even when wine bottles are stored on their sides, one side of the cork is still exposed to air. If the cork begins to dry out, it can allow oxygen to enter the bottle and possibly causing the wine to spoil or oxidize. "Temperature" Keep the temperature constant for extended aging of wine (over 1 year), refrigeration is a must in most parts of the world; even a below-ground cellar is not cool enough. Wine storage temperature should not go over 75ÚF (24°C), for longer than brief spans of time. At 75°F, wine begins to oxidize. An ideal temperature for storing a varied wine collection is 54°F (12.2°C).
