Bordeaux it ain't, but a bunch of people enjoy it anyway. This is my grandfather's recipe for hooch wine, which he made from probably ~ 1930 till he died in 1990. It's pretty sweet--the yeast craps out from the alc. content and leaves residual sweetness.
I've made it several times using concord grapes and also wild plums (delicious). The last time I made it was around 1993, hadn't ever brewed and didn't know a thing about gravity etc.
2 cans Welch's concentrated grape juice
5 cups white sugar
2 packs bread yeast
1 big assed balloon
Mix in 1 gallon jug, top off with water, tie on balloon with string, ferment till balloon deflates, enjoy.
Papa with 2 jugs of his creation, and on his Allis Chalmers model G. We found some of this wine in the shed behind him several years after he died. It was in a flip-top bottle and had turned. Aunt took a swig and promptly ejected it.
