A: Post Company founder Charles W. Post might have been good at creating popular cereals, but he wasn’t the best at naming them. One of his first breakfast treats, Post Toasties, was originally known by the more, er, zealous name, Elijah's Manna. Of course, that's nothing compared to the misleading moniker Grape-Nuts™, which Charles named after a key ingredient in the cereal called maltose. There was some method to his madness, however. Maltose tasted like nuts and, at the time, was known as "grape sugar." Hence, Grape-Nuts™.
It may sound like false advertising, but it’s actually not. The truth is, Post would likely be protected from such allegations by that precious little hyphen. While the Federal Trade Commission might consider a cereal called Grape Nuts "deceitful," the hyphen makes the name "fanciful," which excludes it from prosecution according to the 1906 Pure Food and Drug Act.
