Historically beer styles evolved regionally due to the ingredients that were available to the local brewers.  For example, in Scotland hops did not grow well, and were expensive to import.  So beers produced by Scottish brewers typically had very low level of bitterness and hop flavor, but well developed malt flavors.

The earliest known evidence of beer and brewing comes [[Sumeria]] around 4,000 B.C.  The evidence comes from clay tablets inscribed with the [[Hymn to Ninkasi]], the Sumerian's Goddess of brewing, where the hymn contains a rudimentary recipe for beer.

The Reinheitsgebolt is the first example of a food purity law.  Passed in German in 1516, it decreed that all beers could be made from only water, malt and hops.  After the discovery of yeast and its importance in brewing, it was also added to the list.
