Beer

Beer is a popular beverage consisting of four main ingredients: grain (mostly malted barley), hops that come in a wide assortment, yeast for fermentation, and water, which accounts for up to 95% of the finished product. Each of these four ingredients is responsible for a number of beer's attributes.

Although simple in concept, beer is a highly complex mixture of many compounds including sugars, proteins, alcohols, esters, acids, ketones, acids and terpenes.

It is therefore important to know what happens at every step of the brewing process, to make sure that all the ingredients are free of contaminants or adulterants and the quality of the product is consistent with the expectations.
