Ah!!!
I am attracted to the noise of ridicule and laughter!
Hay is from the grass family, right? So is corn; and in America there were those who used green corn stalks to brew beer; a web search will turn up at least a recipe or two. There's fermentable sugars in them grass family. That's why we use barley, wheat, oats, corn...I imagine that corn stalks do not give the most pleasant homebrew experience, but it used to be done quite regularly in this country.
I would think that since the corn stalk recipes were preserved, they weren't a complete failure, or the recipe s would have been tossed.
Fresh corn stalks smell of sweetness when crushed, not unlike fresh hay or straw. Our forefathers probably noticed this characteristic as well, and, like us, decided to experiment.
Do a search for corn stalk beer and derive a recipe from that. You can make a brew and use the straw to add flavor.
I am curious as to the result of your efforts. Please keep us posted!
