How long does red wine last?

How to tell red wine has gone bad

General signs for beverages, the group USDA lists red wine under.

• Fizzy drinks that have gone flat or taste metallic
• Sour or curdled smell from opened juice or milk alternatives
• Cloudiness or separation that will not shake back together
• Cork pushed slightly out or wine that smells like vinegar
• Mould ring forming at the neck of a bottle or carton

More on beverages. The times above are quality guidelines, not safety limits; food that shows these signs goes out regardless of the date.

Storage habits that make the difference

Refrigerate opened juice, milk alternatives and any dairy-based drinks, and use them within about a week. Store unopened cans and bottles upright in a cool, dark spot away from direct sunlight. Keep coffee and tea in airtight containers away from heat and moisture to preserve flavour longer.
