I have some apple cider that is 4 months old...?!
Answers: how long do I need to wait before it ferments and contains a good alcohol %?
If it turns into vinegar you can pour it on your wang before sex and not use a condom.
I think it will turn to vinegar first if not already.
You need to introduce the proper yeast culture without letting any other bacteria into it. Just sitting by itself it won't turn into anything.
I agree!
its doesnt NEED yeast to make it hard. juice will harned by itself even without it.
