Oxidation in wine

Definition.Oxidation in wine describes chemical reactions between oxygen and components such as phenols or alcohols. These reactions alter the color, aroma, and taste.

Oxidation pathway model.The basis is the oxidation pathway model. It explains the sequence and rate of oxidative reactions in wine. The oxidation pathway model shows how the amount of oxygen, time, and temperature control this development. The oxidation pathway model distinguishes between controlled and uncontrolled oxidation.

Consequence.Oxidation is irreversible. Once triggered, it cannot be reversed and requires precise control in all phases.
