New Beer's Eve (also known as National Beer Day) is an unofficial holiday in the United States, which is observed on April 07, 2021. The day celebrates the end of Prohibition in the United States. Prohibition in the United States was a national ban on the sale, manufacture, and transportation of alcohol, for 13 years in place from 1920 to 1933.
In March 1933, President Franklin Roosevelt signed into law an amendment to the Volstead Act, allowing the manufacture and sale of certain kinds of alcoholic beverages. Sales of beer in the United States would become legal on April 7 provided that the state in question had enacted its own law allowing such sales.
On the evening of April 6, 1933 people lined up outside breweries and taverns, waiting for midnight when they would be able to legally purchase beer again. Since this date, the night of April 6 has been referred to as "New Beer's Eve”.
Beer is the world's most widely consumed and probably oldest alcoholic beverage; it is the third most popular drink overall, after water and tea. It is produced by the brewing and fermentation of sugars, mainly derived from malted cereal grains, most commonly malted barley and malted wheat. (With material from: Wikipedia)
