How does wine spoil and how can you inform if it has gone bad?

Wine is a natural product and, as such, is subject to deterioration. wine spoilage can be categorized as "primary" or "secondary.".

https://sakeradvantage.com/?p=968 Main wine wasting is triggered by the growth of yeast and bacteria in the red wine. These microorganisms are naturally present on the grape skin and in the winemaking environment. If wine is not correctly protected from oxygen, the yeast and bacteria will multiply, resulting in the wasting of the wine.

Secondary red wine putridity is triggered by the growth of mold on the wine. Mold can grow on red wine that has been stored in wet or humid conditions. Mold will not be able to grow if the wine has actually been stored in an Optimum Storage Environment (OSE).

You can tell if wine has actually spoiled if it has actually established an off-odor or if the color has actually changed. Red wine that has spoiled will also have a flat taste.
