The modification of the Volstead Act allows beer to be sold once again. The modification changed the allowed alcohol percentage of a beverage from .05 to 3.2 allowing beer to be served once again. Over 1.5 million barrels of beer was consumed during the first 24-hours after the modification of the Act.
