How Can You Tell If Grapes Have Gone Bad?
You can tell if grapes have gone bad by examining their appearance, smell, and taste. If the grapes are wrinkled, soft, or discolored, they may be no longer fresh. Similarly, on smelling the grapes, if you notice any musty, sour, or vinegar-like odor, it indicates that the grapes have gone bad. And, if the grapes taste sour or have a spoiled flavor, discard them immediately. It is always better to buy fresh grapes and consume them within a few days to avoid any health risks or unpleasant taste.
