As far as something not available commercially, I had a co-worker back in East Tennessee who tried making wine out of potatoes he grew in his backyard. When no one wanted to drink it, he ran it through his still and produced moonshine. Still no one wanted to drink it. He added maple syrup and told people it was homemade "Maple Crown Royal". I took one sip and spit it out. It may very well have been identical in flavor to what he was trying to replicate. I have no idea what came over me. I never drank any of his homemade alcohol again which I suppose was a shame because some of his home brewed beer was okay.
