What is the recommended storage temperature for opened wine to extend its life?

Storing opened wine at refrigerator temperature is recommended to extend its life because cooler temperatures help slow down the oxidation process that occurs once a bottle is opened. Oxidation can lead to the deterioration of the wine's flavors and aromas. When wine is kept in the refrigerator, it typically maintains a consistent temperature range that preserves the wine's characteristics for a longer period compared to warmer conditions.

Room temperature can accelerate the aging process, causing the wine to spoil more quickly. Freezer temperatures are too cold and can damage the wine through freezing, leading to changes in texture and flavor. Warm temperatures also promote oxidation and can result in a loss of desirable qualities in the wine.

Therefore, keeping opened wine in the refrigerator is the best option to maintain its integrity and prolong its freshness.
