How does red wine spoil?

Red wine is a foodstuff made from grapes that have been fermented. Throughout the fermentation procedure, yeast cells transform the sugars in the grapes into alcohol. After the grapes have actually been pushed and the red wine has been bottled, the yeast cells are no longer active and the white wine will not continue to ferment.

White wine putridity is triggered by the development of bacteria and fungi. These bacteria are found naturally on the skins of grapes. They can also enter the wine through contact with filthy equipment or polluted air.

Bacteria and fungi grow in warm, damp conditions. They also need oxygen to grow. When these conditions are present, fungis and bacteria will increase quickly and ruin the wine.

Red wine wasting can cause the white wine to develop smells and off-flavors. Wine that has actually spoiled should be discarded.
