Beer out of Grape Nuts?

I’ve either been reading way too much beer research of late, or there has to be a workable beer recipe found in the cereal aisle of your local grocery store.

In perusing the ingredient list of a box of Grape Nuts cereal, I read the following:

Whole grain wheat flour, wheat flour, malted barley flour, salt, dried yeast, soy lecithin

So, am I crazy, or is there a basic beer ingredient list in here?

What prevents me on committing to my belief that one could make beer out of Grape Nuts and Grape nuts alone is the fact that to get any taste out of the cereal, one would have to bring the Grape Nuts to a healthy temperature, somewhere between 160 and 180 degrees F. Temperatures this high would kill the dried yeast present in the grain, so new yeast would have to be added. This is easily done by using certain types of grapes, or even, apparently, purple cabbage.

Others out there have added grape nuts to standing beer recipes, which isn’t using Grape Nuts exclusively. There are second hand reports of others having made a weak beer with a Grape Nuts mash. But I’ve yet to come across anyone on the Internet who said, “Yes, you can make a beer primarily with Grape Nuts.”

So, is it possible?
