Grapeheads followed Lemonheads which were invented by Ferrara Pan Candy Company. The formula was developed in 1962 using the same method as Red Hots, another Ferrara Pan candy product. Both of these candies are made using the cold panned process.
This process involves building candy pieces from candy centers and tossing them into revolving pans while adding flavor, color and other candy ingredients. The process continues until the pieces become the desired size. Grapeheads used to be called Alexander The Grape but the name was changed in an attempt to take advantage of the popularity of Lemonheads.
As a kids, I remember this candy better known as Alexander the Grape. My brother and I would go to the local candy store and buy boxes of this candy and others (Red Hots, Lemonheads, Boston Baked Beans) and when we were done with the boxes, we would fold the flaps inside the box and blow inside the box making a funny sound.
My brother, a few friends and I would get a bunch of these boxes and make a small symphony. When one box would get wear out from either saliva or just being over used, we'd use our other empty boxes and keep going. We'd drive our parents up the wall! ~ Bill from Pennsylvania
