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.
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.
