Beer in the United States
On January 16, 1919, the Eighteenth Amendment to the United States Constitution was enacted into law, creating the Prohibition era, wherein the production, sale and transportation of alcoholic beverages was made illegal. All legal American brewing came to a halt when prohibition was imposed, though the earlier temperance movement had already reduced the number of breweries significantly. Only a few breweries, mainly the largest, were able to stay in business by manufacturing near beer, malt syrup, or other non-alcohol grain products, in addition to soft drinks such as colas and root beers. Production and shipping of alcohol was largely confined to illegal operations that could deliver compact distilled beverages—smuggled rum and domestic moonshine—more efficiently and reliably than bulkier products such as beer.
Culture of the United States
A movement to ban alcoholic beverages, called the Temperance movement, emerged in the late 19th century. Several American Protestant religious groups and women's groups, such as the Women's Christian Temperance Union, supported the movement. In 1919, Prohibitionists succeeded in amending the Constitution to prohibit the sale of alcohol. Although the Prohibition period did result in lowering alcohol consumption overall, banning alcohol outright proved to be unworkable, as the previously legitimate distillery industry was replaced by criminal gangs that trafficked in alcohol. Prohibition was repealed in 1933. States and localities retained the right to remain "dry", and to this day, a handful still do.
