Until this moment, I've never thought about it. Without the husks, it could gum up the works something fierce if you use very much of it, so you need to account for that. I don't know if you would need to mash the toasted wheat germ, and I don't know that you need to cereal mash the untoasted.
Unless there is something just particular about wheat germ you want, it seems like an expensive way to add wheat to a beer, no matter what.
Beer is good for anything from hot dogs to heartache.
