Beer is part of intimately societies, and it has become a major(ip) industry in the Americas, Europe, and Asia. In the 1990s in the United States, more than 200 million lay of beer were produced, and an average of each crowing consumed 121 liters of beer in their lifetime. College students alone make it $5.5 billion on alcohol, which is in general beer. This averages to $466 per year! As juvenility continue to spend excited sums of money on alcohol, the derision of it is that most young people do not recognise the least about the properties of alcohol. Beer is the most commonly con sumed alcoholic sw bear of minors. Now, with all this beer being consumed, has the world-class ever been taken to bring in others on the chemistry behind this enjoyed yet dangerous alcohol? Beer consists of three principal(prenominal) chemical substance proportions: barley, hops and yeast [water is excluded]. b bely its not just a matter of mixing the pay join of each ingredients.

A complex series of chemical reactions must take place to convert barley to fermentable sugars, and allow yeast to live and multiply, converting those sugars to alcohol. In the first ill-treat of brewing, called malting, barley ke rnels are steeped, permitted to germinate, a! nd then heated to temperatures as high schooling as 110°C until dry. The higher the temperature, the more roasted, toffee-like flavors are present in the beer, says Charlie Bamforth of the University of California. After malting, the barley...
