Most people would consider fermented fruit some kind of wine. I've had something described as barley wine before, but it was just very strong beer.
Whiskey and beer wort is very similar, so you might be on to something with the "distilled beer" comment. Never heard it described like that but it gets the point across. If you go on a whiskey tour, they introduce you to the mash, wort, and brewing process before getting into distillation. I think most people would insist on having their beer fermented, though :)
Even the Germans gave up pretending beer was only made from barley. The wheat prohibition ("purity law") was political anyway.
