Chemistry Can Tell A Beer’s ‘Home’

SEVILLE, Spain, Dec. 1 (UPI) — Spanish researchers say they’ve developed a technique based on chemistry that is 99 percent accurate at revealing the country of origin of beer.

Measuring the content of iron, potassium, phosphates and polyphenols, researchers at the Spanish Foundation for Science and Technology correctly identified German, Spanish and Portuguese beers, a foundation release said Thursday.

“Beers can be differentiated from one another according to their country of origin by using parameters linked to raw materials, such as water (metals and negatively charged ions) and the type of hop (polyphenol content),” Jose Marcos Jurado, a chemist at the University of Seville, said.

“The differences can seem very subtle but the model is capable of detecting the relationship between these chemical descriptors and the country of origin of beers,” he said.

Authenticity and geographical identification studies are “very important” for the food industry, researchers said, “given that they allow the differentiating characteristics of a product to be established.

“This can have an impact on their marketing.”

    Damn! WHY didn’t I think of this? Many deep, burning philosophical questions have plagued mankind for hundreds of years. Yet it took until recently to solve the biggest, worst one of them all. How do we find a beer’s home?
    We can’t have just ANY beer being sold unless we know its complete background. There’s beer and there’s BEER.
    It wouldn’t be right to buy some beer, only to find that it was made in Iran instead of France. One must have STANDARDS. Now I can sleep at night, knowing that the world’s finest brains have solved this elusive problem. Group hug!
    I just knew that if I lived long enough, this problem would be solved. Let’s celebrate, world. I’ll buy the first round. Cheers!
