The oldest document yet discovered by man, a clay tablet inscribed in Babylonia around 6000 B.C., depicts the preparation of beer for sacrificial purposes. Two thousand years later, the Babylonians had made over sixteen different types of beer using wheat, barley, and honey. Today, imported beers are very popular in the United States where over one hundred foreign beers have a small hold on the market. European beer is by far the most popular, with the German beers topping the charts. The Dutch beer Heinekin is also very popular, as is the Mexican beer, Corona.
Beer is the product of the fermentation of sugar into alcohol by yeast.
The prime ingredients are barley, malt extract, and hops. To make beer, barley is soaked in water for hydration, sprouted, then dried to form malt. Beer can be filtered or pasteurized, then charged with carbon dioxide to give the tingling taste. Beers are divided into a variety of types. Lager beers are stored for a period of time to allow a second fermentation to occur.
