Global warming will change the beer flavor

Leave a Comment
Much of what we have for granted today will be in the medium term, as the climate change on knock and are changing the way we have become accustomed to certain products. One of them is the beer, whose flavor will never be the same.

Who says is the PhD student Peter Gous, who is worried about the effects of climate on production of beer and, therefore, decided to investigate this link at the University of Queensland, Australia.

The study was published in the Journal of Cereal Science and tested as the lack of water can affect the quality of the grains of barley. Gous believes that the starch in the barley grains grown with little water is different from starch from grains of barley well watered. Barley that grows with little water has a kind of hydric stress, what changes the structure of the starch.

From this discovery, Gous raised the hypothesis that, in the future, it will be more difficult to consume a quality beer. That's because climate change will make droughts more frequent and more severe in all the world. This can affect the quality of grains, such as barley used in beer.

This means that consumers will have to pay more for a beer with the same quality of today. "If you ask any Brewer, the starch quality and fermentation affect the taste of beer," explained Gous the Brisbane Times. "Rather than pay €3,6 ($ 11) for a beer, for example, will pay € 10 to €14 ($ 33 to $ 44)," he concluded.

And the reader is willing to pay that amount for a beer?
