wine collection temperature
Before Opening. 1  1. Keep it in the dark. Store all wines away from light, especially direct sunlight and fluorescent fixtures. 2  2. Store corked wine bottles on their sides. If they are stored upright for a long amount of time, the corks will dry out, and air will eventually get to the wine, spoiling it. 3  3. 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 75ËF (24Â°C), for longer than brief spans of time. At 75Â°F, wine begins to oxidize.
