Wine making from pasteurized grape juice?

It will be suitable for making wine as long as it doesn't contain a preservative. It is good to be pasteurized. You actually don't want the wild yeast it it. That only works well when the grapes are grown in completely natural organic ways, like they did 1000 years ago. Just add yeast to it. Fleischman's rapid rise yeast is a very good wine yeast.
