Chicha is a beer made from corn that is widely used (and abused) in Central and South America. It is often consumed while still fermenting and low in alcohol. It is generally slightly sour. Chicha may also be spiced with almost anything, or fruit may be added to the ferment or at the time of serving.

Chicha has been made for thousands of years, most notably by the Incas, who brewed it on a commercial scale.
