Did you have chicha prepared the 'artisanal' / traditional way described in the article...

This part—the chewing—plays a key role in the fermentation process, since enzymes from saliva convert the starch to sugar, which, when combined with wild yeast or bacteria, eventually becomes alcohol. The preparers then spit the resulting juice into a clay pot, where it ferments for several hours. After that, voila: Chicha is born

Chicha is spit?!?

Few concepts have been found to be independently discovered and adopted across the history of disparate human civilizations. Don't kill members of your own tribe. Incest is bad. Find a way, any way, to make booze. :-)
