Chicago
The ratification of the 18th amendment to the Constitution in 1919 made the production and sale (including exportation) of alcoholic beverages illegal in the United States. This ushered in the beginning of what is known as the Gangster Era, a time that roughly spans from 1919 until 1933 when Prohibition was repealed. The 1920s saw gangsters, including Al Capone, Dion O'Banion, Bugs Moran and Tony Accardo battle law enforcement and each other on the streets of Chicago during the Prohibition era. Chicago was the location of the infamous St. Valentine's Day Massacre in 1929, when Al Capone sent men to gun down members of a rival gang, North Side, led by Bugs Moran.
American wine
Following the repeal of Prohibition in 1933, operators tried to revive the American wine-making industry, which was nearly ended. Many talented wine-makers had died, vineyards had been neglected or replanted with table grapes, and Prohibition had changed Americans' taste in wines. During the Great Depression, consumers demanded cheap "jug wine" (so-called dago red) and sweet, fortified (high alcohol) wine. Before Prohibition, dry table wines outsold sweet wines by three to one, but afterward, the ratio of demand changed dramatically. As a result, by 1935, 81% of California's production was sweet wines. For decades, wine production was low and limited.
