How Can You Tell If a Wine is Too Oxidized?

What is Wine Oxidation

Wine becomes oxidized when exposed to oxygen. Some oxygen exposure is inevitable and a natural part of the aging process. However, wine that has been exposed to too much oxygen is said to have become oxidized.

What Causes Wine Oxidation?

Wine oxidation is caused by a variety of factors including:

  • Excessive Heat Exposure

  • Excessive Light Exposure

  • Humidity

Heat

Prolonged exposure to heat beyond a wine’s optimal storage temperature will cause a wine to become oxidized. Long story short, heat expedites the aging rate of wine. For example, every 18°F increase in temperature doubles the aging rate of wine. This is why it is so important to ensure you are storing your wine at the right temperature. Read:

Humidity

Humidity is critical to wine storage. No less than 50% humidity is recommended with 65-70% being most ideal. Anything above 80% will likely cause the formation of mold around the cork.
