Wine oxidation and how to prevent from it | mysterydishes

Wine oxidation is a common issue that can have an impact on the flavor and scent of wine. When wine is exposed to air, chemical reactions occur, which can result in a loss of taste and fragrance. However, winemakers may take precautions to avoid oxidation and protect the quality of their wine.

Firstly, it is critical to understand the process of oxidation. When wine is exposed to oxygen molecules, the chemicals in the wine react, resulting in the production of new compounds. These responses can produce a loss of fruitiness, freshness, and complexity, as well as a brownish color and a stale, nutty taste in wine.

To prevent oxidation, it is important to minimize the wine's exposure to air throughout the winemaking process. This can be achieved through a variety of techniques, including:

Use of sulfur dioxide: Sulfur dioxide is commonly used in winemaking as a preservative. It is effective at preventing oxidation by binding with oxygen molecules and preventing them from reacting with the wine. However, it is important to use sulfur dioxide in moderation, as excessive amounts can lead to off-flavors and aromas.

Proper bottling: After aging wine, it is critical to bottle it swiftly to prevent oxygen from entering the bottle. This can be accomplished by employing a filling equipment that injects inert gas into the bottle before filling it with wine, or by filling the bottles under vacuum on a bottling line.

Uses of oxygen scavengers: Oxygen scavengers are compounds that absorb and eliminate oxygen from wine. These can be used to avoid oxidation during the bottling process.

Alternative closures: Traditional cork closures can let small amounts of oxygen into the bottle over time, causing oxidation. Screw caps or synthetic corks, for example, can be more successful in preventing oxygen from entering the bottle.

To avoid oxidation, wine should be stored in a cool, dark, and damp atmosphere once it has been bottled. Wine should be kept horizontally to keep the cork wet, which aids in keeping air out of the bottle.
