How fizzy does fresh coconut juice have to be before it is undrinkable?

Question

Bought two coconuts - one's juice is soft n sweet, while other is a bit more fizzy. I've had fizzy ones before - to the extent it was more like carbonated water, but how fizzy can it get before it's not a good idea to drink it? Aparently the older, the fizzier.

Answer 1

What's happening is they are becoming alcoholic. That's what's causing the fizziness. So the questioin is, how bombed do you want to get?
