How Can You Tell When Apples Are Bad?
You can tell apples are bad by looking for physical signs like wrinkles, soft spots, bruises, discoloration or mold. A bad apple may also emit a sour or musty smell. Overripe apples may be mushy or mealy inside, while underripe ones may be hard and sour. To ensure freshness of apples, choose firm and shiny apples, and store them in a cool and dry place away from heat and moisture.
