Yeah, I’ve ruled out the fruit. In the future, I would like to try some from a flavor perspective: cranberry Apple cider, ginger (I know it’s not a fruit) Apple cider, etc.
You wont find juice without sulfides (yeast killer) and ginger is an antimicrobial. Kills yeast. To make ginger beer you have to spend weeks culling the weak yeast in a gingery environment to get them to have resistance to the ginger. The downside is it seems to breed the alcohol production right out of them. Garlic does too. So do onions. Don’t ask me how I know. I have tried some strange brews.
I will say sugar cane, coconut and most tropical fruits make some killer brews. Just make sure you hop them well to prevent the nasty bacteria that like the those environments. (Hops kill bacteria but not yeast)
