Some of the first vessels were used to ferment alcohol in Western China around 8,000 years ago, says Robert Dudley, a professor of biomechanics and comparative physiology at the University of California, Berkeley. And hawthorn berries, a tangy, nutrient-rich fruit that grows on trees and shrubs in Europe and Asia, made the world’s first booze, he says.

We’ve only been intentionally fermenting beverages for a small fraction of our history, but we evolved to metabolize alcohol before we were even human, says Dudley.
