One of the regions of Belgium produces a beer of barley malt and wheat by
spontaneous fermentation called lambic. Some varieties have a fruit
component which is added to the wort and fermented. It is usually produced
in Winter and early Spring to reduce the possible contaminents. So
spontaneous fermentation can produce a beverage that humans can drink.
Strains of yeast tend to be localized, so you may or may not have a wild
yeast in your vicinity that will produce a satisfactory result.
Simple fermentation of fruit juice produces wine. Wine has been made for at
least 8000 years and the original vintners didn't have cultivated yeast, so
I'm fairly certain that people can drink the result of a spontaneous
fermentation of fruit or fruit juice. The safety and palatablity of doing
so are different issues.

True lambics are generally tank brewed and are flat. If carbonation is
desired, it is by secondary fermentation during bottling. If I were doing
this experiment, I would use a container with a pressure release valve.

Lambics and other spontaneous fermentations are notoriously sour tasting.
Ferment it cool and pasteurize the resulting wine after straining, but that
will eliminate natural carbonation.
