Neither grapes nor nuts have ever been ingredients in the cereal. The original formula for Grape-Nuts called for grape sugar, which is composed mostly of glucose unlike most other sugar sources and food sweeteners which are principally sucrose. This, combined with the "nutty" flavor of the cereal inspired its name. Another explanation originates from employees at Post who claim that the cereal got its name due to the cereal's resemblance to grape seeds or grape "nuts". - Wikipedia
