No, we’re not making this up. Would we ever pull a prank on the good readers of Growler Fills? According to co-founders Justin Smith and Mike Connolly, National Beer Day is a celebration of the end of Prohibition:

“In 1933 during the prohibition era, the Cullen-Harrison Act was signed into law by President Franklin Roosevelt on March 23rd. That law was enacted on April 7th allowing the brewing and sale of beer in the United States again as long as it was < 3.2% (4% ABV). It's said that people waited in line overnight on April 6th outside Milwaukee breweries in order to legally buy beer for the first time in over 13 years. As a result, April 7th is known as National Beer Day and April 6th is called New Beers Eve. So this April, tell all your friends about this glorious new holiday, and raise a glass, bottle, can, or mug to the deliciousness that is beer."
