April 7 marks the anniversary of the day beer was legally allowed to be manufactured and sold following the end of Prohibition in the US.

On March 22, 1933, the Cullen-Harrison Act was signed into law by President Franklin Roosevelt, allowing the manufacture and sale of beer that contained up to 4% alcohol by volume and some wines.

Beer has a close relationship to tax, and here are a few more interesting facts about beer to celebrate its anniversary.
