Man has been brewing beer for about the past eight thousand years. For the most part, early brewers were experimentalists who produced various mixtures for themselves and their friends and family. Today, the beer industry has a multi-billion dollar market and competition is stiff with literally thousands of commercial brewers around the world. The oldest document yet discovered by man, a clay tablet inscribed in Babylon around 6000 BC, 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.
European beer is by far the most popular, with the German beers topping the charts.
The Dutch beer Heineken is also very popular, as is the Mexican beer, Corona. 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. Lager beers are stored for a period of time to allow a second fermentation to occur.
