A little something I learned a while back: one packet bread yeast (wine yeast best) in a half gallon of good grape juice minus a cup or so as it foams plus 2 days time=potable alcohol. It tastes funky but makes ya smile! I figured it out years back when the company was on hiatus, money was tight, and they say ya can’t buy alcohol on food stamps. But nobody said you couldn’t buy the components! Sure beat the hell outta nothing’ to drink! Down time is boring...
Yeah, that works, but a couple refinements for you:
- add a cup or two of sugar. More sugar=more alcohol once it is done fermenting.
- put a large balloon (or UN-lubricated condom) over the top of the grape juice bottle. This prevents spillage, and gives you an indicator as to when the fermentation is finished. The balloon will inflate with carbon dioxide as the juice ferments, then the balloon will deflate once the fermentation is over.
- Pour the end result through a coffee filter to get rid of the yeast sludge that is left over, that will help a lot with the flavor.
