Grape-Nuts have been around for over a hundred years. They’ve accompanied the first climbers to reach the summit of Mount Everest, they were fed to soldiers in WWII, and they sponsored the Andy Griffith Show. But why is the wheat and barely cereal called Grape-Nuts?
Two stories prevail. First states that Mr. Post thought that glucose formed during the baking process. Another name for glucose is grape sugar. This combined with its nutty flavor made ‘Grape-Nuts’.
The other theory is that the cereal kernels look like grape seeds or ‘grape nuts’.
