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.
Pardon My Scotch
"Pardon My Scotch" was filmed on April 11-15, 1935, four months after the ratification of the Twenty-first Amendment to the United States Constitution which ended the American experiment with Prohibition. This event is an integral part of the storyline, with the drugstore owner (Al Thompson) frantically attempting to lay in a stock of liquor in anticipation of the imminent end of Prohibition.
