Babbling Beverage is a potion that caused the drinker to babble nonsense.
During the 1986–1987 school year, as the Prefect, who welcomed Jacob's sibling to their House, was graduating at the end of that school year, as a parting gift, three private lessons were taught to Jacob's sibling, Babbling Beverage being one of them.
In 1995, when Dolores Umbridge had become Headmistress, Parvati and Padma Patil secretly brewed the potion and, with help from Harry Potter, used it on Umbridge's loudspeakers. This was just one of the many sabotages on Umbridge's reign.
In 1996, Harry Potter, convinced that Sirius Black was in trouble at the Department of Mysteries, gave a cryptic warning to Severus Snape. Professor Snape, pretending he did not understand, replied that he would use the Babbling Beverag if he wanted nonsense shouted at him.
