Gloria (played by Sophia Vergara) in the series Modern Family has a special tradition on New Year's Eve that involves eating 12 grapes. In the "New Year's Eve" episode from the 2013 season, it is shown that Gloria strongly believes in this tradition and needs 12 grapes for her luck.
This belief has become part of the New Year's celebration culture in many communities, including in Spain and Latin America, and has been proven by several people through their personal experiences as shown in the now-viral TikTok video. Where did it originate?
