I made some of the wine last year. I got 2 gallons of welches 100% grape juice, the 100% is the important part. I put those 2 gallons in a 3 gallon container along with some sugar and yeast and a baggie with holes in it the cover the opening. Sure enough by party time(about 5 days) I had drinkable alcohol. It was this weird opaque purple color and tasted pretty bad, so I gave the two gallons to the first idiot that said it tasted good. In all I can say I made my own wine but in the end it costed more than getting two bottles of two buck chuck. Which would have been easier and more sanitary to get ahold of.
