Do you celebrate National Beer Day on April 7th every year? Did you even know that we have a National Beer Day? We do! And it’s all thanks to our 32nd president, Franklin D. Roosevelt and his signing of the Cullen-Harrison Act. Celebrated across the country in 1933, the act was just one small step on the path to the ratification of the 21st Amendment and the final nail in the coffin for Prohibition.
