I use Vinters Harvest 96oz cans of juice. I just finished bottling my blueberry and it turned out nice, a little strong at 13.5% ABV though. I make 6 gal batches so I also add 3 or 4 cans of the 11.5 oz welches frozen 100% juice. This keeps it from getting too thin. There are directions on the can as well. Just remember, check the SG. The welches frozen juice has sugar in it so you don't need to add as much sugar as the directions call for. I shoot for an SG of 1.080 to start.
