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

White wine is made through a fermentation process of the sugars in grapes turning into alcohol. Over time, that fermentation process will continue and the white wine will develop into vinegar. That's why an old, unopened bottle of red wine will likely be vinegar.

You can inform if white wine has gone bad if it has a distinct vinegar smell, if it tastes unpleasant, or if it has altered color. If it has any mold growing on it, it's likewise a sign that it's gone bad.

If you're uncertain if your red wine has actually spoiled, it's much better to err on the side of care and discard it. Red wine that has actually gone bad will not make you sick, however it's not going to taste great either.

To avoid your white wine from spoiling, ensure to store it correctly. Wine ought to be saved in a cool, dark place where the temperature is reasonably consistent.  link There must not be any significant modifications in temperature or light direct exposure. White wine should also be stored upright so that the cork doesn't dry out and let air into the bottle.
