Yes, I used to do it all the time and I used bread yeast to do it.
It tasted fine. I would use Welches grape juice and add bread yeast for baking bread, about half a package, then put a paper towel over the top to keep ants and flies out but let the air filter in and out.
It took about only three to five days to turn from grape juice to good tasting wine, and sometimes I used pineapple juice or other fuit juices. I even made wine out of orange juice and it was a cheap fun high.
However, but there was one problem and I quit doing it.
. I think some of the yeast stayed alive because I never heated it up and it started to grow in my intestines and caused bloating for months after I ate something sweet. The yeast in me made me crave sweets. And whenever i ate even a piece of bread or potatoe, which is carbs that the body turns into sugar, I'd get uncomfortably bloated! The yeast would grow in my belly.
I had to go on a sugarless high protein diet with a lot of yogurt for a few months to get rid of it.
Therefore, I don't recommend you do it, even though you can and it tastes really good, but you might suffer for a long time afterwards. I bet that you could heat up the home made juice wine though and kill the yeast. I'm not sure how that would affect the taste, but you could avoid the bloat and live yeast from growing inside of you that way.
I also know of a man who used to brew his own beer who got intestinal yeast as a result of it. He had problems for years and had to stop drinking it was such a big problem for him.
I never tried it myself because after I got that bloat I just quit drinking entirely and never went back to it. I was so tired of having that yeast in me I just stopped drinking after than. And I feel ghreat! There is just as much anti-oxidant in grape juice as there is in wine, and you get to keep all ;your brain cells... which is a good thing.
