                                According to food scientists, storing grapes correctly can extend their shelf life by up to three weeks. The common assumption that an airtight plastic bag is best is, in fact, a mistake that accelerates spoilage. Grapes, like other produce, require proper ventilation to prevent moisture buildup, which creates the perfect environment for mold to thrive.
