Facing the possibility climate change could significantly increase the price of beer, a Queensland researcher is on mission to drought-proof the amber fluid.

And he thinks he has found the solution.

A Queensland researcher is working to drought proof beer.

The incorporation of the so-called “stay-green” traits first identified in sorghum could mean a more stable supply of carbohydrates for the brewing process, University of Queensland researcher Peter Gous said.

Mr Gous said a changing climate could affect grains “horribly”, with the amount of starch in non-stay-green samples put under water stress in a pilot study fluctuating more than those with the stay-green genetic traits.
