If you want to try a 'new' kind of winemaking, and not have it take you to the poorhouse by buying sugar, try making wine out of commercial Jelly.
I ran unto this a few years back when I was trying to make Cranberry wine. I had so much trouble trying to make Cranberry because I could not find the right dilution of the juice and have the yeast survive that I did a search for alternatives.
I found a recipe for making wine out of Jellied Cranberry Sauce, and it worked perfect. Not only did it contain the correct dilution, but the sugar was already in there. I added nothing but something to make the pectin settle to the bottom after fermentation was complete.
I told my buddy about this and he made a batch out of Strawberry Jelly, all without adding any sugar because it is already in the jelly. It came out perfect. Now he even makes it out of those Coctail Mixes that are in the supermarkets. You would have to add sugar to those though.
So....if you want to make wine on the cheap, try making it out of Jelly. Just make sure you buy A-1 products and they only use sugar as a sweetener.
