How does white wine ruin and how can you tell if it has gone bad?

You can tell if wine has actually spoiled if it has a distinct vinegar odor, if it tastes undesirable, or if it has changed color. It's also an indication that it's gone bad if it has any mold growing on it.

If you're unsure if your wine has actually spoiled, it's better to err on the side of care and discard it. White wine that has actually spoiled won't make you ill, but it's not going to taste excellent either.
