Chimps 'go off on boozing binges'

science

Chimpanzees in West Africa get drunk during lengthy binges featuring the fermented sap of palm trees - normally used to make palm wine - a new study says.

The report focused on chimps in Guinea, which use palm fronds to soak up the fermented sap of raffia palms that can contain up to 6.9pc alcohol - stronger than most beers.

"The habitual and voluntary consumption of ethanol has been documented until now only in humans," said Kimberley Hockings of Oxford Brookes University.

The chimpanzees in Guinea are unique because their alcohol consumption is not the result of any human interaction, the report said.
