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.
History of California wine
The destruction of the American wine industry would come not from "phylloxera" but from Prohibition in the United States. Thirty-three states had gone dry at the outbreak of World War I. Wartime Prohibition was enacted in 1919, followed by the Volstead National Prohibition Act and the 18th Amendment to the U.S. Constitution in 1920, forbidding the "manufacture, sale, or transportation of intoxicating liquors."
