A new study found that beer producers may need to raise the price of beer, since over the next 80 years, barley – a key ingredient in beer – may well be clipped by growing bouts of extreme heat waves and drought.

In fact, this study published in the peer-reviewed British journal Nature Plants noted that losses of barley yield may exceed 17 percent.

Researchers in China, along with Steven J. Davis, an environmental scientist at the University of California, Irvine, used models of both economic activity and climate change on 34 regions around the world to show barley may well become a scarce commodity, with farmers preferring to feed it to their livestock, rather than divert it to domestic breweries.

“That,” said Davis, “makes sense. This is a luxury commodity and it’s more important to have food on the table.”
