The actual Purity Law is a result of the Bavarian Duke Wilhelm IV. The reason to institute such a law was mainly the poor quality of “Beers” at that time and the deaths caused from the poisonous materials used.

The original text stated that the only ingredients that could be used in the production of beer were water, barley and hops.

No yeast was mentioned in the original text despite what many people believe.
