Is there a way to tell if a wine is spoiled?

Yes, there are several ways to tell if a wine is spoiled. First, check the color of the wine. If it has turned an unusual shade or is cloudy in appearance, this could be a sign that it's gone bad. Second, smell the wine. If it has an off odor, such as a musty or moldy smell, then it may have gone bad. Third, taste the wine. If it tastes sour or metallic, it could be spoiled. Finally, look at the expiration date on the bottle and see if it has passed.
